The cement is made up of limestone and other minerals, which act as a binding agent when combined with water. The crushed rocks, stones and sand in the concrete are called aggregates, which are held in place by the cement and help give the concrete strength and act as an extender in order to use less cement.
When mixing separate bags of cement and lime, hydrated lime must be completely wetted out in the mixing process or it will continue to absorb water after mixing. By following the proper mixing procedures, excellent board life, workability and sand carrying capacities are achieved with lime mortars.
Concrete is a material used in building construction, consisting of a hard, chemically inert particulate substance known as an aggregate (usually made from different types of sand and gravel), that is bonded together by cement and water.
Stenciled concrete A decorative surface treatment using heavyduty paper stencils with stone, tile, or patterns that are lightly pressed into fresh concrete, followed by the application of dryshake color hardeners. When the stencils are removed, the uncolored concrete mimics mortar joints.
