Abstract

The invention relates to a corrosion-resistant glass fiber-reinforced composite (GRC) product. The corrosion-resistant GRC product comprises: by mass, 39 to 41% of low-alkali ordinary portland cement, 13 to 13.3% of water, 40 to 40.3% of hard sand, 5 to 5.3% of a water reducer, 1 to 1.2% of glass fibers and 0.5 to 0.8% of silica fume. The corrosion-resistant GRC product adopts low-alkali ordinary portland cement. Low-alkali ordinary portland cement has low corrosiveness to glass fibers and silica fume of the corrosion-resistant GRC product can effectively improve the composition of cementing materials of a cement stone and reduce the content of Ca(OH)2 and thus the durability of the corrosion-resistant GRC product is improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a corrosion-resistant glass fiber reinforced cement mixture product. Background technique [0002] Sandstone products or their art are developed along with the development and progress of human beings. Today, the use of sandstone products has penetrated into many aspects of people's lives, such as architecture, decoration, gardens and so on. For example, the invention patent with the Chinese patent number ZL200910012001.7, announced on November 25, 2009, discloses a thin-walled GRC imitation sandstone product based on glass fiber reinforced cement. The thin-walled structure includes a base layer, a back layer and The surface layer is formed on the mould, and the composition and content of the base layer are: 25-40% of low-alkali cement or ordinary Portland cement, 25-30% of quartz sand or ordinary sand, and 3-5% of alkali-resistant glass fiber , 10-15% needle-shaped wollastoni...
