DSM Durability & Workability

Durability & Resistance

CEMEX Dry Silo Mortar is also extremely durable due to the controlled method of manufacture and the type and quality of the constituent materials used. The entrainment of controlled amounts of air makes the mortar less susceptible to frost attack. The admixture used is chloride-free and therefore not aggressive towards embedded metallic objects. Factory produced mortars exhibit superior resistance to rain penetration and therefore make a significant contribution to the durability of masonry.


CEMEX Dry Silo Mortar when blended with water offers excellent workability without an excessive air content, the inclusion of which can weaken the bond and flexural strength.
