A 0.35 oz. Type M mortar is considered to be the strongest and needs to be used only when working with stone. The standard formulation meets or exceeds ASTM C-270 Type âMâ specifications. Check out our blog! More. Type M Portland Cement is sometimes referred to as Type M Mortar, Type M Portland/Lime or Type Mary. The mortar strength in the wall will be much higher than the field test because of the reduced water cement ratio due absorption of mix water into the masonry units and a greatly reduced shape factor in the mortar joint versus the mortar test cube. A type M mix has the highest highest amount of Portland which gives it a minimum of 2,500 psi of compressive strength. In general, well graded aggregates reduce segregation in a plastic mortar, which in turn inhibits bleeding and improves workability. Type S mortar is the most common for the Arizona market so we will use this as the basis for our comparisons. Mix until the mortar becomes consistent and looks to be workable. 4j) is a hydraulic cement similar to masonry cement, with the added requirement of a minimum bond strength requirement. Unsure of which mortar type to use? To mix you will need a five gallon bucket or a wheelbarrow, depending on the size of the project, a hoe, a trowel, work gloves, water, and liquid cement color and safety glasses. Water We'll also take a good look at masonry cement. You know what type of mortar you need? Types N or NA lime are not typically used in mortar; however, they are permitted if shown by test or performance record to not be detrimental to the soundness of the mortar. ASTM C207 limits the amount of unhydrated oxides in Type S or Type SA hydrated limes, assuring the soundness of mortar made using these limes. for pricing and availability. A hydraulic cement produced specifically for use in mortar for unit masonry construction. Sold in Stores Masonry Cement Type N - 70 lb. Type M â Requires a 2500 psi/full cure 1). MAG B550M MORTAR. Masonry cements are classified as Type M, Type S, or Type N according to ASTM C270. Building codes generally specify mortar types as referenced in ASTM C270, Standard Specification for Mortar for Unit Masonry (ref. The aggregate ratio noted in Table 2 must be followed. Type S mortar is specified as a medium strength mortar and is generally used for below grade â¦ Each mortar type has its own uses and works best with only certain types of materials. This is the property of most importance to the mason. Type M (used for below grade load-bearing masonry work and for chimneys and brick manholes) Type S (used for below grade work and in such areas as masonry foundation walls, brick manholes, retaining walls, sewers, brick walkways, brick pavement and brick patios) Type O (lime rich mortar, also referred to as âpointingâ mortar) Many properties of mortar are not precisely definable in quantitative terminology because of a lack of definitive standards by which to measure them. Use of air-entrained cement or lime generally results in decreased water demand, improved workability, increased freeze-thaw resistance, and decreased bond strength. Gradation limits are established in ASTM C144 for both natural and manufactured sands. Depending on the particular circumstances for a given project, the criteria for mortar selection are based on design considerations, mortar properties in the plastic state or mortar properties in a hardened state. In seismic design categories , D, E, and F portland cement/lime or mortar cement mortar Types S or M are required (ref. Click to add item "Mortar Mix Type S - 80 lb" to the compare list. Bond is a term used to describe both the extent of contact between mortar and unit and the strength of adhesion. Colored masonry cement is premixed with pigments to offer a wide range of color. The various material options alter the characteristics of the mortar in a predictable manner. Oversanding or overtempering can decrease durability. This generally is not harmful as long as it is done prior to hydration of the mortar. Conformance to the property specification of ASTM C270 is established by testing laboratory prepared mortar during a pre-construction evaluation of the mortar proposed for the project. Similarly, the Specifications for Masonry Structures (ref. These proportions are then followed when preparing field mortar. Sand 4. Meets the requirements of ASTM C270 types S, N, or M. Data Sheet - Bulk Masonry Mortars & Grouts Data Sheet - Mason Mix Guide â¦ Type M mortar is generally used with stone, since itâs very strong and wonât fail before the stone does. In seismic design categories, D, E, and F portland cement/lime or mortar cement mortar Types S or M are required (ref. However, ASTM C1324, Standard Test Method for Examination and Analysis of Hardened Masonry Mortar, (ref. It consists of highest amount of Portland cement with compressive strength ranging from 1800-3000 psi (13- 21 MPa). Also, masonry cements (ref. To get 1 cuyd of M mortar, you need 27 cubic feet of the components in a 3 to 1 to 12 proportion. The proportion specification (Table 1) prescribes the parts by volume of each ingredient required to provide a specific mortar type. Once mix proportions have been established, the addition of water should be consistent with that required to improve mortar placement without sacrificing the ability to support the masonry unit. 4d) is a hydraulic cement (sets and hardens by chemical reaction with water) and is one of the main constituents of mortar. For example, empirical design of foundation walls requires Type M or S mortar and glass unit masonry requires Type N or S mortar (ref. CEMEXâs Type N Masonry Cement, Type S Masonry Cement and Type M Masonry Cement are specially formulated and manufactured to produce masonry mortar. original mortar as opposed to pointing mortar or other mortars used on the project. Portland Cement 2. Other factors being equal, bond strength will increase as the compressive strength of the mortar increases, although not in direct proportion. 11. for pricing and availability. Compressive strength is perhaps the most commonly measured property of mortar but is perhaps the most misunderstood. Mortars with low water retention stiffen more quickly, making it difficult for the mason to bed and adjust the masonry unit during placement. CEMEXâs Type N Masonry Cement, Type S Masonry Cement and Type M Masonry Cement are specially formulated and manufactured to produce masonry mortar. Manufactured sand is the product obtained by crushing stone, gravel, or air cooled blast furnace slag. This is a manufactured, premixed, packaged combination of Portland cement, hydrated lime and optional admixtures. Admixtures (also sometimes called modifiers or additives) for masonry mortars (ASTM C1384, ref. Only one of the specifications should be called for in the project documents, not both. Bond is a function of several factors including mortar properties, unit surface characteristics, workmanship, and curing. White masonry cement should meet the requirements of ASTM C91 for Type N, S or M masonry cement. The mortar mix can be bought at most hardware stores or home improvement stores. 2004 Annual Book of ASTM Standards, American Society for Testing and Materials. 3.

Item #866490. While this mix is great for supporting heavy loads and below grade foundations, it provides relatively poor bonding and sealing properties. Sands deficient in fines generally produce harsh mortars, while sands with excessive fines typically result in mortars with lower compressive strengths. Types S or SA (slag cement) may also be used in mortars meeting the property specification requirements of ASTM C270 (Table 2 of this TEK). The time lapse between spreading a mortar bed and placing block should be kept to a minimum, because the workability will be reduced as water is absorbed into the block. Type M mortar has the highest strength. Available in type M mortar, type S mortar and type N mortar which all meet ASTM C 270, ASTM C 1714 and CSA A179 requirements. Model #866490. Evaporation of the mixing water from mortar may require retempering (mixing in additional water). Add water as needed, but use it sparingly. This type of mortar is generally used with hard stone. ASTM C 780 recognizes this and states that the strength should not be construed as being representative of the actual strength of the mortar. Sand acts as a filler and provides body to the mortar while helping to reduce shrinkage and control cracking. However, Types M, S, and N are typically required by building codes. 3) limits admixtures to no more than 0.2% chloride ions. Adequate water content promotes intimate contact between the unit and mortar, which is essential for satisfactory bond. Type M used in below ground applications for heavier load bearing applications, usually for foundations to support , and has a compressive strength of 2,500psi. Bond may also be effectively increased through the use of properly designed mortars having water contents which provide good workability. Water for masonry mortar (ASTM C270, ref. Compare; Find My Store. In addition, within these mortar types, there are mortars specifically designed for use in stone veneer and glass block installations. The names for these mortar types, developed in 1954, were based on alternating letters of the phrase "MASON WORK". Slaking of hydrated lime is not required, thus hydrated lime is immediately usable and much more convenient than quicklime. Lime Mortar/Type L â Not really a type or mortar or a mortar alone by means of the definition of the word (mortar). This type of mortar is long lasting and will continue to hold its strength for as long as the stone remains. The Appendix of ASTM C270 provides a reference to which mortar type should be used in some general â¦ Item #293036. Sku # 1891180. This mortar is used for below-grade applications involving extreme pressure or lateral loads, such as foundations and retaining walls. Specifications Usage. Different types of mortar exist for a variety of applications. If you have questions about specific products or services we provide, please don’t hesitate to contact us. To avoid the stiffening effects of hydration, mortar must be placed in final position within 2½ hours after the original mixing (ref. Since it closely mimics the strength of stone, it will not fail before the stone itself fails. If too much time elapses before a block is placed on a fresh mortar bed, units are less easily positioned and the bond will be reduced. (10g) sample is usually sufficient for both the petrographic and chemical analysis. 4i) provides procedures for petrographic examination and chemical analysis for components of masonry mortar in the hardened state. Because they are produced â¦ A workable mortar spreads easily under the trowel; adheres to vertical surfaces during unit handling, placement, and bedding; maintains alignment as other units are positioned; and provides a watertight, closed joint when tooled. Hydrated Lime 3. For example, mortars can be rated on the basis of obtaining visually satisfactory mortar joints. Admixtures are functionally classified as bond enhancers, workability enhancers, set accelerators, set retarders, and water repellents. 4b) or mortar cements (ref. Aggregates (ASTM C144, ref. 4a) is calcined (burned-decarbonated) limestone, the major constituents of which are calcium oxide (CaO) and magnesium oxide (MgO). For example, empirical design of foundation walls requires Type M or S mortar and glass unit masonry requires Type N or S mortar (ref. Tuck Pointing Mortar. A combination of portland cement and lime may be used as the cementing agent in each type of mortar. Consequently, design allowable flexural tension values vary based on mortar type and cementitious materials or lime used for unreinforced masonry (ref. The increased porosity of this mortar can help protect movement of material it surrounds. While mortar represents only a small proportion of the total wall area in concrete masonry construction (approximately 7 percent), its influence on the performance of a wall is significant. 4k) are available for various purposes. ASTM C207 designates Type N (normal), Type S (special), and air-entraining Type NA and Type SA hydrated limes. In addition, Type N masonry cement can be combined with portland cement or blended hydraulic cement to produce Type S or M mortars. What is Tuckpointing – Uses and How It Is Done, Self Leveling Cement – Advantages and How To Pour. With the diversity of materials available, masonry mortars can be formulated to produce the desired properties for most specific job requirements. 4f). 4b) is a hydraulic cement consisting of a mixture of portland cement or blended hydraulic cement and plasticizing materials (such as limestone, hydrated or hydraulic lime) together with other materials introduced to influence such properties as setting time, workability, water retention, and durability. These properties are difficult to measure other than in laboratory or field specimens prepared under controlled conditions. The type of mortar you need will depend on your intended use. Mortar is generally comprised of sand, lime or cement and water. Stone Veneer 80-lb Gray Type-N Mortar Mix.
