Limestone-Cement

Limestone powder has been widely used in cement-based materials; and reportedly, can influence their properties by filler, nucleation, dilution and chemical effects. The filler effect of Limestone Powder refines the microstructure and reduces the porosity of cement-based materials. Its nucleation effect accelerates the hydration of C3S, increases the number of hydration products and reduces the porosity of cement-based materials at early ages. Its dilution effect reduces the hydration peak of C3S, decreases the number of hydration products and increases the porosity of cement-based materials. W Moreover, Its chemical effect promotes the appearance of a third hydration peak, forms Carboaluminate and reduces the porosity of cement-based materials.
