Abstract

The invention provides a biomass power plant ash-based autoclaving-free aerated concrete sound absorbing and insulating brick and a preparation method thereof. The aerated concrete sound absorbing and insulating brick is basically prepared from, by weight, 10%-15% of cement, 45%-54% of coal ash, 12%-20% of rice hull ash, 1%-9% of perlite, 3%-5% of an excitant, 8%-12% of lime, 2%-4% of gypsum, water accounting for 49%-52% of the total weigh of dry materials, aluminite powder accounting for 0.07%-0.1% of the total weight of the dry materials, a water reducing agent accounting for 8.5%-8.8% of the total weight of the dry materials and a foam stabilizer accounting for 10% of the water reducing agent, wherein the dry materials are the combination of cement, coal ash, rice hull ash, perlite, excitants, lime and gypsum. According to the aerated concrete sound absorbing and insulating brick, resourceful utilization of biomass power plant ash is achieved, moreover, the brick has better sound absorbing and insulating performance and heat conducting performance. The preparation method of the brick has the advantages that operation is easy, and autoclaving is avoided.

Description

technical field [0001] The invention belongs to the technical field of concrete sound-absorbing and insulating bricks, and in particular relates to ash-based autoclaved-free aerated concrete absorbing and sound-insulating bricks for biomass power plants and a preparation method thereof. Background technique [0002] Once upon a time, the creation and use of various mechanical equipment brought prosperity and progress to human beings, which were considered a symbol of modern industrial development, but today, the noise in the city has seriously troubled people's lives. With the development of economy and society, contemporary noise pollution is becoming more and more serious, and various diseases caused by noise are increasing day by day, devouring people's health. Therefore, noise pollution has become the fourth largest pollution in the world after air pollution, water pollution and solid waste pollution. [1] . To control the noise, you can reduce the noise of the sound ...
