UNIFORM UNHARDENED CEMENT NATURED COMPOSITION AND METHOD FOR ITS PRODUCTION

摘要

Cementitious compositions having a modulus of rupture greater than 20 MN/m2 are prepared by subjecting a mixture of hydraulic cement, fine aggregate, a selected water-dispersible polymer and water to a homogenisation process (in order to very substantially reduce voidage in the product) and by thereafter curing and drying the product. The aggregate improves the modulus of rupture and resists any loss in this strength property due to moisture uptake and loss.
