The advantage of dry-mixed mortar

0 Comment

Dry-mixed mortar or dry mortar is made of cement, sand, mineral and functional additives, mixing together proportionally. It is often in powder or granule form pre-mixed in special factory and transported to construction site. After stirring with adequate amount of water, it can be used directly. There are usually two kinds of dry mortars- normal type.. read more →

The Water Retention Functions and Principles of Hydroxypropyl Methylcellulose The HPMC mainly plays a role in water retention and thickening, able to effectively improve the bond force and sag resistance of slurry. Air temperature, humidity, wind pressure and other factors will affect the evaporation rate of water in cement mortar and gypsum-based products. Therefore, in.. read more →

The mechanism by which concrete shrinkage cracking occurs is as follows. In setting and hardening of concrete, the volume will change and the set cement will generate heat of hydration. Due to different rates of temperature increases and decreases on the surface or in the inner part of components, shrinkage deformation of concrete will be.. read more →

Aggregate for dry mix mortar

0 Comment

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 →
