GRC's Chinese name is glass fiber reinforced concrete. This is a reinforcing material, cement mortar reinforced cement composite material with alkali resistant glass fiber as a. At present, China's production of GRC are mainly dominated by cement, sand, fiber and water, will also add certain polymers, additives, to improve product performance.

Cement is the most basic material, is a material can not be missing. Commonly used in the GRC cement mainly will fast hardening sulpho aluminate cement, low alkalinity sulphoaluminate cement, ordinary portland cement, white portland cement. This will guarantee the performance and quality of GRC.

Fiber is a material composed of GRC, but in GRC when the fiber must be of alkali resistant glass fiber. This is because the alkali resistance of fiber can make GRC have more excellent performance. In addition, the content of the fiber in the entire GRC is also provided, otherwise it is not guaranteed the quality of the product. At present, the amount of GRC in the production of our country is not less than 16.5%.

Sand and water are the two components of the other, is indispensable. Sand's role is to ensure the concrete coagulation effect; water is mainly doing the adjustments in the use, thus ensuring the cement, fiber, sand and other materials according to a certain proportion to cooperate and ultimately produce high-quality GRC.

Polymers and additives can improve the performance of GRC. Polymer is generally added to the polymer for the acrylic emulsion, which is acrylate copolymer emulsion. Mainly choose admixture superplasticizer, retarder, plasticizer, early strength agent and other products, so as to enhance product performance.

As long as the composition of the material in accordance with a certain proportion of the configuration, then you will be able to ensure that the production of high quality GRC, thus to meet the needs of the market.
