LimeCement

Limestone provides high water retention that allows for maximum early curing of the cementitious materials. High initial flow which permits easy complete coverage of masonry units. The low air content of cement-lime mortar increases bond strength.

The lime cement is whipped into the masses, which then hardens and stabilizes. The mixing ratio is usually 50/50 cement and burnt lime. The cement contributes to strength, while burnt lime contributes to plasticity.

Why mix burnt lime with cement?

Limestone can be used as a cement replacement in concrete. There are, as there have always been, two critical issues with this type of cement replacement: the change in physical properties with respect to compressive strength and the cost analysis of the alternatives.
