The environment-friendly type concrete punching brick has the advantages that science and technology content is high, raw material is green and environmentally friendly, intensity and heat resistance accord with a national standard, the raw materials are sold on market, cost is low, science and technology content and product added value of the building manufacturer enterprises can be effectively increased, and the concrete punching brick can establish a base for increasing the economic benefit for the enterprises.
Description
technical field [0001] The invention belongs to the field of building materials, in particular to a method for preparing an environment-friendly concrete perforated brick. Background technique [0002] Air-entrained concrete block is a new type of building material that is lightweight, porous, thermally insulated, good in fire resistance, can be nailed, sawed, planed, and has a certain degree of earthquake resistance. It is an excellent new type of building material and is environmentally friendly. Etc. [0003] However, the content of the currently commercially available aerated concrete blocks is too high, resulting in the strength of the aerated concrete blocks exceeding the standard, which cannot meet the environmental protection requirements, and the raw material problem and poor process control are prone to uneven distribution of pores inside the aerated block And too bulky. [0004] After searching, a patent document related to the content of this application was fo...
