Embodiment Construction

[0014] An anti-seepage water aerated concrete block, made of the following raw materials in parts by weight (kg): cement 20, quicklime 15, gypsum 10, fly ash 45, aluminum powder 0.2, lignosulfonate 2, slag 20 , Cotton straw powder 10, grape vine powder 10, waste engine oil 3, sodium persulfate 2, glutinous rice flour 2, appropriate amount of water.

[0015] The preparation method of anti-seepage water aerated concrete block is characterized in that it comprises the following steps:

[0016] (1) Add an appropriate amount of water to the glutinous rice flour, boil it into a thin paste soup, stir, add waste engine oil, then add cotton straw powder and grapevine powder, stir for 30-45 minutes, then add lignosulfonate and sodium persulfate , after stirring for 30-45 minutes, add gypsum and stir into mud;

[0017] (2) Add cement and fly ash to 60-70°C hot water and mix for 10-15 minutes, then add the mud obtained in step (1), quicklime, aluminum powder and other materials, and stir...

Abstract

A seepage-proofing aerated concrete building block and a preparation method thereof are disclosed. The building block is composed of following raw materials in parts by weight: 20 to 25 parts of cement, 15 to 20 parts of quicklime, 10 to 15 parts of gypsum, 40 to 45 parts of fly ash, 0.1 to 0.2 part of aluminum powder, 1 to 2 parts of sulfonated lignin, 20 to 25 parts of slag, 10 to 15 parts of cotton straw powder, 10 to 15 parts of grapevine powder, 2 to 3 parts of waste engine oil, 1 to 2 parts of sodium persulfate, 2 to 3 parts of sweet rice flour, and a right amount of water. The aerated concrete building block adopts oil foot and waster engine oil components, which have been modified by initiator, to increase water-resistance ability of the building block, and the seepage-proofing ability of the building block is also largely improved. The seepage-proofing aerated concrete building block has been used in an outer wall body of a community for more than 3 years, and no seepage phenomenon has been found. But adopting conventional aerated concrete building blocks, every spring resident houses have seepage phenomenon. Sweet rice flour is used to prepare pulp, which can fill the cracks in the building block to reduce the possibility of seepage.

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 an anti-seepage aerated concrete block and a preparation method thereof, so as to solve the problem of easy water seepage existing in the current aerated concrete block. [0004] Technica...
