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.

Type S mortar is specified as a medium strength mortar and is generally used for below grade … 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 “pointing” 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.

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 … 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.
