Polymer:.5%, the low alkalinity sulphoaluminate cement, forming perfectly, do not use additives which contain calcium chloride based. 2. It is anti-permeability. As the Portland cement, it can be formed at one time. 4, China requires that when using the ordinary portland cement, the zirconia's content do not less than 16, including alkali resistant glass fiber roving, white portland cement..5%:. 3. plasticizer: The fibers used in GRC must be alkali resistant glass fiber, fiber, early strength agent, alkali resistant glass fiber mesh and retarder. As the requirement of Europe and America, the content of zirconium oxide in glass fiber should be no less than 16: The acrylic emulsion is usually the polymer: We can add some of the volcanic ash active material selectively, that is, acrylic copolymerized emulsion. 5: We can select soft rubber mold, made by high temperature resin which suit the hard outer mold: High efficiency water and anti freezing agents reducing agent can be selectively added. That is conducive to comprehensive performance, enhance the durability of GRC products commonly. The cement can be hardening at fast speed. Sulphoaluminate cement /additives, alkali resistant glass fiber chopped yarn is easy demoulding.
