Aggregate is one of the most important constituent materials of dry-mixed mortar. It mainly acts as skeleton and reduces the volume change caused by hygroexpansion during setting and hardening, and also as an inexpensive filler for cementitious materials. There are natural and artificial aggregates depending on its source- natural kind such as gravel, pebbles, pumice,.. read more →

Lime is the first nonhydraulic cementitious material used in construction. Due to its rich raw materials, simple production equipment and low-cost, it is still widely used in construction projects. The raw material for lime is mainly rock which mainly contains calcium carbonate. The most commonly used raw material is limestone, in addition to dolomite and.. read more →

Gypsum is an inorganic air-hardening cementitious material, mainly consisting of calcium sulphate. Using gypsum materials and relevant products have great significance for saving building materials resources and improving the technical level of building materials. Production cost, Raw material consumption, construction technology requirements and equipment costs are low and production efficiency is high. Gypsum materials have.. read more →
