Below by Baotou GRC What do you recommend GRC Good products can be made only by selecting European components:
1. Mold: High temperature resin soft rubber mold can be selected to match with hard outer mold. One time molding, easy demoulding and perfect shaping.
2. Cement: cement commonly used in GRC mainly includes quick hardening sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary Portland cement and white Portland cement.
3. Fiber: The fiber used in Changsha GRC material is alkali resistant glass fiber, including alkali resistant glass fiber roving, alkali resistant glass fiber chopped yarn, and alkali resistant glass fiber gridding cloth. European and American countries require that the zirconia content of glass fiber used in GRC shall not be less than 16.5%, and China requires that the zirconia content of ordinary Portland cement shall not be less than 16.5%.
4. Polymer: usually added polymer is acrylic emulsion, namely acrylate copolymer emulsion.
5. Admixtures: Generally, superplasticizer, plasticizer, retarder, early strength agent, antifreeze, rust inhibitor and other admixtures can be selectively added: when products contain steel reinforcement materials or steel embedded parts, calcium chloride based admixtures shall not be used.
6. Other materials: some pozzolanic active materials can be selectively added to improve the comprehensive performance of GRC products, such as strength, impermeability, durability, etc.
