Calcium sulfoaluminate CAS powder (lumps) is a new type of intermediate product in the building materials industry developed under the strong support of relevant experts from the National Building Materials Academy. It can not only be used to produce special cement, but also use its special properties such as early strength, early setting, micro expansion, low alkalinity, non-shrinkage, etc., to produce various types of high-quality grouting materials, repair materials, anchoring agents, expansion agents and preparations Waterproof, leak-stopping, early strength and other special engineering materials.

ZWSA high-efficiency plugging agent is the latest technological product developed under the guidance of relevant experts from the China Academy of Building Materials Science. It is characterized by extremely short setting time interval, rapid heat generation after final setting, and strength, 15min strength not less than 12MPa, lh strength not less than 24MPa, can work with water, and quickly stop water and leak, and the construction is simple, and the base layer Strong adhesion, no shrinkage, no falling off, can be widely used in housing, underground, underwater, tunnels and other projects for leak stoppage, emergency repair, irrigation, etc.
