Abstract

The invention relates to a kind of concrete stepping piece as well as preparing method. The ingredient of the invention includes cement, lime, gypsum, pulverized coal ash, diatomaceous earth, vapor-generating agent, foam stabilizer and regulator. The advantage of the invention includes careful choice of materials, simple and scientific producing procedure, light volume weight, good anti-shake ability and good incubation and heat insulating ability. The stepping piece is water-proof and fire-proof. It is very cheap and can be used as the out wall material of the high buildings; besides, it can be used in industry where needs incubation. The invention can make full use of the waste pulverized coal ash and save energies, so the invention has provided an ideal stepping piece and preparing method.

Description

1. Technical field: [0001] The invention relates to an aerated concrete block and a production method thereof, in particular to an autoclaved fly ash 300 bulk density refractory heat-retaining aerated concrete block and a production method thereof. 2. Background technology: [0002] There are 500-700 grades of aerated concrete blocks at present, and there is no 300 grades of refractory and thermal insulation aerated concrete blocks, which is a deficiency in the prior art. 3. Contents of the invention: [0003] The purpose of the present invention is to invent a kind of fly ash 300 bulk density refractory thermal insulation aerated concrete block and its manufacturing method. Insufficient air-entrained concrete blocks. [0004] The object of the present invention can be achieved through the following embodiments: the weight percentage of the raw materials of this building block is: cement 7-9%, lime 21-23%, gypsum 1%, fly ash 45-50%, silicon 22-23% of algae earth, 0.26% o...
