KMA contains Krystol technology. When added to cementitious mortars or concrete masonry units, Krystol chemically reacts with water and unhydrated cement particles to form insoluble needleshaped crystals that fill capillary pores and microcracks in the concrete and block the pathways for water and waterborne contaminants.
Introduction 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. Materials The materials which could be used in a cementlime mortar are defined in ...

ACRYLOK is a highsolid, acrylic polymer latex admixture and bonding agent. This milky white liquid is nonyellowing in Portland cement mortars and concrete. When used as an admixture, ACRYLOK provides increased abrasion, impact and crack resistance, flexural strength, and freeze/thaw tolerance. Permeability is also reduced, providing added protection from chloride intrusion and scaling.

Jun 09, 2010· Rapidhardening hydraulic cement has been used for both concrete repair and new construction, wherever superior durability and rapid strength gain are required. It is blended and packaged into a wide range of highperformance products including nonshrink grout, structural repair mortar, concrete, exterior plaster, and other cementitious products.
Rheological and Mechanical Properties of Mortars Prepared with Natural and Manufactured Sands. The conventional assessment methods for fine aggregate used in Portland cement concrete are mostly based on round natural sand performance in spite of the increasing use of angular manufactured sands.
In this study, the blended cements produced by using the building stone waste were exposed to sulphate solution and the cement properties were examined. Prepared mortar specimens were cured under water for 28 days and then they were exposed to three different proportions of sodium sulphate solution for 125 days. Performances of cements were determined by means of compressive strength and ...
