Mortar is a workable cementitious material, used as a binder between various masonry units.

Portland Cement/Lime Mortar is comprised of various ratios of mason sand, portland cement, hydrated lime, and water depending on application.

Masonry or plastic cement is comprised of portland cement, ground limestone and an air-entraining agent that allows for more workability.

Concrete and mortar are ubiquitous materials in construction, but with different purposes. Both contain portland cement, water and aggregate, but the mixes for each reflect the desired characteristics.

Mortar is used to bond masonry units together. It doesn’t need the strength of concrete; however, it needs good bonding characteristics. Mortars with a high water-cement ratio bond best. This is the opposite of concrete, where concrete mix is formulated for strength and lower water content makes it stronger and more effective for its purpose. Additives or plasticizers may be added to mortar mixes to increase their flexibility.

Concrete is categorized into two primary categories, plain concrete, and structural concrete. Plain concrete is any structure supported by the ground, such as walkways, driveways, slabs, and spread footings to support masonry walls. Plain concrete is often reinforced with steel to increase its tensile strength against temperature fluctuations that threaten its structural integrity.

Structural concrete is any structural piece made of concrete that has points of support and requires the capacity to hold loads, such as concrete beams, suspended concrete slabs, or concrete pilings.

Adhesion or Bond: It should be capable of developing good adhesion with the building units such as bricks, stones etc.

Durability: It should be able to resist freeze thaw and other environmental conditions.

Resisting penetration of rainwater: The porosity should be tight enough to resist wind driven rains and not shrink allowing the bond between the mortar and masonry unit to separate.

Workability: It should spread easily without the addition of too much water and retain the water to allow for a good bond.

The German Smear is a technique that can be done with most mortars and/or stuccos. It is all in how the individual wants to finish the surface.

The AMX 400 Series is a factory blend of portland cement, hydrated lime and dried (mason) sand.

The AMX 500 Series is a factory blend of masonry cement and dried (mason) sand.

While both types perform similarly, most masons will have a preference for one of the other.

RainBloc GP is a factory-engineered, integrated moisture protection and water repellant that can be integrated into Amerimix mortars. This patented, mortar rheology agent is also the only moisture protectant that is traceable, detectable and measurable, giving you the peace of mind that what you specified is what you get.

Amerimix WRM with RainBloc GP is part of the total RainBloc system. When used with CMUs that contain RainBloc, it creates a wall system that has been proven in both the lab and jobsite to inhibit water penetration, creating a superior moisture barrier. For added assurance, all components of the RainBloc system are warranted.
