Embodiment 1

[0049] Weigh each raw material according to the weight shown in Table 1, first add water, then add color material, start the mixer to stir evenly, then add cement, after stirring for two minutes, add quartz sand, then add mortar, water reducing agent, metakaolin, pozzolan and methyl silicate, stir evenly to prepare cement mortar; use air pressure (6Kg / cm 2 ) chopping the glass fiber inside the concentric and coaxial spray gun, and automatically mixing it with the cement mortar to prepare glass fiber cement mortar with a glass fiber weight percentage of 5%;

[0050] The cement mortar is sprayed from the spray gun to the mold by air pressure to obtain a 3mm thick surface layer. The surface layer is sprayed twice: the first spraying is 1-1.5mm, and the next spraying is 1.5mm after 5-10 minutes. Left and right; Roller compaction is used to expel the air bubbles and increase the density. The spraying method is alternately carried out horizontally and vertically; after about 4 to 5 ...

Embodiment 2

[0053] In the preparation method of the GRC product of this embodiment, the back material layer is three layers, each layer is 3 mm, and the rest is consistent with the embodiment 1, and a GRC product with a thickness of 12 mm is obtained.

Embodiment 3

[0055] In the preparation method of the GRC product of this embodiment, the back material layer is nine layers, each layer is 3 mm, and the rest is consistent with the embodiment 1, and a GRC product with a thickness of 30 mm is obtained.

Abstract

The invention discloses a GRC (glass fiber reinforced cement) product which is prepared from cement, glass fibers, quartz sand, water, rubber paste, a water reducing agent, metakaolin, volcanic ash and methyl silicate. The combination of the water reducing agent, metakaolin, volcanic ash and methyl silicate is used as an enhancer and used as a raw material of the GRC product. The combination of the water reducing agent, metakaolin, volcanic ash and methyl silicate is mixed with the cement, glass fibers and water, so that the water reducing agent, metakaolin, volcanic ash and methyl silicate can generate mutual synergistic actions; and thus, the GRC product has excellent bending resistance and tensile resistance, and the service life of the GRC product is maximally prolonged. When being used in a building, the GRC product has the same service life as the building. Besides, the raw materials used in the GRC product are from reprocessed natural or waste products, and thus, are green and environment-friendly.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to a GRC product. Background technique [0002] GRC (Glass Fiber Reinforced Concrete), also known as GFRC, the Chinese name is glass fiber reinforced cement or glass fiber reinforced concrete, is a kind of composite material mixed with glass fiber as reinforcing material and cement mortar as basic material. Some GRC products have problems of insufficient tensile, bending and impact strength. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a GRC product with very good tensile, flexural and impact strengths. [0004] For this purpose, the present invention adopts the following technical solutions: [0005] Provided is a GRC product whose raw materials include: cement, glass fiber, quartz sand, water and mortar, water reducing agent, metakaolin, pozzolan and methyl silicate. [0006] Among them, glass fiber (Glass Fiber) is an inorganic non-met...
