Problems solved by technology

[0003] At present, the main component of processing and manufacturing air-entrained concrete is fly ash or sand. Due to the high cost of fly ash or sand itself, and because the country needs macro-economic regulation and control, the construction industry has entered a low tide, which has greatly reduced the profit of air-entrained concrete manufacturing. In particular, sand is used to make air-entrained concrete wall materials. Due to excessive sand mining, it is not advisable to greatly affect the ecological environment.

Abstract

The invention relates to an aerated concrete wall material and a preparation method thereof, in particular to an aerated concrete wall material containing river silt and a preparation method thereof. The aerated concrete wall material comprises the following main components in percentage by weight: 60-75% of river silt, 1-10% of cement, 13-28% of lime, 1-2% of gypsum powder, 6-10% of aluminum powder and 2-11% of foam stabilizing agent, and the sum of weight percentages of the components is 100%. In the invention, river silt dug out by regulating the Yangtze River can be effectively utilized, energy is saved, emission is reduced, the ecological environment is protected, and the processed aerated concrete wall material also has high compressive strength and high bending strength.

Description

technical field [0001] The invention relates to an aerated concrete wall material and a preparation method thereof, in particular to an aerated concrete wall material containing river silt and sand and a preparation method thereof. Background technique [0002] The traditional bricks used in construction generally use solid clay bricks as sintered ordinary bricks (commonly known as red bricks). Most of these bricks are made of cultivated land clay, which seriously damages the cultivated land and causes the loss of a large amount of land resources. Simultaneously in its burning process, also can waste a large amount of fuel and cause air pollution. In addition, the current red bricks have many disadvantages such as heavy weight, poor processing performance, and poor sound insulation performance. With the progress of society and the rapid development of construction and decoration industries, more and more attention is paid to the requirements for aerated concrete wall materi...
