Embodiment Construction

[0012] A fiber-reinforced aerated concrete block, characterized in that it is made of the following raw materials in parts by weight (kg): cement 18, quicklime 18, gypsum 15, fly ash 30, aluminum powder 0.2, triethanolamine 2, glass Fiber 8, sodium sulfate 2, sodium hydroxide 2, asphalt 12, sodium persulfate 3, oil bottoms 2, ferrocene 2, alum powder 8, trioctyl trimellitate 2, diatomaceous earth 40.

[0013] The preparation method of the fiber-reinforced aerated concrete block is characterized in that it comprises the following steps:

[0014] (1) Add appropriate amount of water to fly ash and alum powder, heat to 70-80°C, stir for 15-20 minutes, add oil foot, glass fiber, sodium hydroxide, stir for 10-15 minutes, then add sodium persulfate , triethanolamine, after stirring for 10-55 minutes, add gypsum and stir for 20-30 minutes, and stir into mud;

[0015] (2) Add cement and diatomaceous earth to 90-100°C hot water and mix for 10-15 minutes, then add the mud obtained in st...

Abstract

An aerated concrete block reinforced by fibers comprises the components, in parts by weight: 18-22 parts of cement, 15-18 parts of quick lime, 12-15 parts of gypsum, 30-35 parts of fly ash, 0.2-0.3 part of an aluminum powder, 2-3 parts of triethanolamine, 8-10 parts of glass fibers, 2-3 parts of sodium sulfate, 2-3 parts of sodium hydroxide, 10-12 parts of asphalt, 3-5 parts of sodium persulfate, 2-3 parts of foots, 1-2 parts of ferrocene, 8-10 parts of an alum powder, 2-3 parts of trioctyl trimellitate, and 30-40 parts of diatomite. The glass fibers are employed in the raw materials, and thereby significantly increasing the strength of the block; and at the same time, the glass fibers have low cost, and thus can be popularized and promoted.

Description

technical field [0001] The invention belongs to a building material technology, in particular to a concrete block and a preparation method thereof. Background technique [0002] As a new type of wall material, air-entrained concrete is a low-energy, environmentally-friendly new building material, which belongs to the building materials promoted by the state. However, because ordinary air-entrained concrete is made of cement, fly ash, quicklime, gypsum, etc. Large shrinkage value, low strength, water seepage, no corrosion resistance, poor heat insulation, single source of material, etc. Therefore, further research on aerated concrete block technology is urgently needed to further meet market requirements. Contents of the invention [0003] The object of the present invention is to provide a fiber-reinforced aerated concrete block and its preparation method to solve the problem of low strength of the current aerated concrete block. [0004] A fiber-reinforced aerated concre...
