Abstract

The invention discloses a crack-proof GRC composite prefabricated member and a manufacture method thereof. The crack-proof GRC composite prefabricated member comprises a GRC surface layer, a GRC structure layer and a concrete layer, which are consolidated as a whole, wherein the GRC surface layer and the concrete layer are respectively disposed at two sides of the GRC structure layer. In the invention, the weight proportion of quartz sand to cement, the weight proportion of quartz sand of 80 mesh to quartz sand of 60 mesh, and the weight of ceramic micropowder in the GRC surface layer are adjusted to thereby effectively reduce the drying shrinkage rate and the crack generation rate of GRC surface layer so that durability and decoration effect of the GRC surface layer and crack-resistance are improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an anti-cracking GRC composite prefabricated component and a preparation method thereof. Background technique [0002] As a composite material, GRC (Glassfiber Reinforced Concrete, glass fiber reinforced concrete) has good tensile and flexural strength, as well as good toughness, and is widely used in colorful building facade decoration and various building products. Prefabricated component technology has been actively promoted and applied at home and abroad for its significant advantages such as improving the efficiency of housing construction, improving the overall quality of housing, reducing costs, reducing material consumption and energy consumption. At present, the general practice of using GRC materials for building exterior walls is to construct the exterior walls first, and then hang GRC decorative panels. If the external wall adopts prefabricated components, since the...
