3. Many properties of mortar are not precisely definable in quantitative terminology because of a lack of definitive standards by which to measure them. This is then blended to create a strong mortar with excellent plasticity and bonding properties. It is used for projects that need to withstand extreme gravitational forces and hold large lateral loads. In addition, Type N masonry cement can be combined with portland cement or blended hydraulic cement to produce Type S or M mortars. PROMIX® Type “M” Mortar is a pre-blended product using Portland Cement, lime and well graded masonry sand. A 0.35 oz. There are 6 specific types of mortar available. Admixtures are functionally classified as bond enhancers, workability enhancers, set accelerators, set retarders, and water repellents. Slaking of hydrated lime is not required, thus hydrated lime is immediately usable and much more convenient than quicklime. Sand acts as a filler and provides body to the mortar while helping to reduce shrinkage and control cracking. It consists of highest amount of Portland cement with compressive strength ranging from 1800-3000 psi (13- 21 MPa). The document also limits pigments for coloring to no more than 1 to 10% by weight of cement depending upon the pigment type. 4b) or mortar cements (ref. Water retentivity is dependent on properties of the cementitious materials, sand gradation, and mortar proportions. This stands true for any mix that is blended and bagged by a manufacturer or mixed by hand in the field. CEMEX’s Type N Masonry Cement, Type S Masonry Cement and Type M Masonry Cement are specially formulated and manufactured to produce masonry mortar. Types I (normal), II (moderate sulfate resistance), and III (high early strength) are permitted according to ASTM C270 (ref. Click to add item "Mortar Mix Type S - 80 lb" to the compare list. 4h) and is only to verify the consistency of materials and procedures, not to determine mortar strength (ref. Consideration of each is necessary to achieve a desired result. For example, mortars can be rated on the basis of obtaining visually satisfactory mortar joints. 1136) is a high strength Commercial Grade dry pre-blended mixture of sand and cements specially selected for masonry applications. Lime imparts workability, water retention, as well as some limited cementitious and autogenous healing properties. Then add the dry mix to the water and cement color. White mortar can also serve as a medium for colored mortars and produces cleaner, brighter colors than grey mortar. To get 1 cuyd of M mortar, you need 27 cubic feet of the components in a 3 to 1 to 12 proportion. Argos masonry cement is specially formulated for use in construction projects using brick, block or stone. 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. Type M Mortar Type M mortar is the highest strength mortar (minimum 2500 psi) and should only be used where significant compressive strength is required. Type … 1). 80-lb Gray Type - S Mortar Mix. Aggregates which fail these gradation limits may be used, as long as the resulting mortar complies with the property specification requirements of ASTM C270, as shown in Table 2. 50-lb Gray Type- High Heat Mortar Mix. Different types of mortar exist for a variety of applications. Sku # 1891180. As an alternative, approved materials may be mixed in controlled percentages as long as the resultant mortar meets the physical requirements designated in ASTM C270, as shown in Table 2. Bond may also be effectively increased through the use of properly designed mortars having water contents which provide good workability.
