1. Cement: generally used for GRC Cement mainly includes quick hardening sulphoaluminate cement, low alkalinity sulphoaluminate cement, ordinary Portland cement and white Portland cement.
2. Fiber: Baotou GRC The fiber used in the material shall be alkali resistant glass fiber, including alkali resistant glass fiber roving, alkali resistant glass fiber chopped yarn and alkali resistant glass fiber gridding cloth. Requirements of European and American countries. The zirconia content of GRC glass fiber shall not be less than 16.5%. When ordinary Portland cement is used in China, the zirconia content shall not be less than 16.5%.
3. Polymer: The polymer usually added is acrylate copolymer emulsion.
4. Admixtures: high range water reducer, plasticizer, retarder, early strength agent, antifreeze, rust inhibitor and other admixtures can usually be selectively added: Baotou partition board When the product contains steel reinforcement materials or steel embedded parts, calcium chloride based admixtures shall not be used.
5. Other materials: some pozzolanic active materials can be selectively added to improve the comprehensive performance of GRC products, such as strength, impermeability and durability.
There are many types of reinforced glass fiber, such as short fiber yarn, continuous fiber roving, mesh cloth, chopped fiber mat, etc. The mixing methods of different types of glass fiber and cement matrix are different, and the mixing methods of the same type of glass fiber and cement matrix are also different. In addition, the mixing amount and application method of glass fiber have a great impact on the mechanical properties of glass fiber reinforced cement composites.
