Problems solved by technology

At present, the commonly used porous concrete materials are mainly used for wall insulation, but less in the application of sound-absorbing materials. At present, the sound-absorbing performance of concrete sound-absorbing materials is low. Noise performance, when the amount of ceramsite added is about 60%, the noise reduction coefficient can reach 0.6, because the preparation of ceramsite requires high-temperature calcination, so the cost is relatively high

Abstract

The invention relates to a biomass porous concrete sound absorption material which comprises the following raw materials in parts by mass: 60-65 parts of mud, 30-35 parts of water, 0.1-0.2 part of a foaming agent, 0.6-2 parts of an anti-cracking enhancer, 0.01-0.02 part of a flatting agent and 1-5 parts of a biomass material, and the foaming agent comprises lauryl sodium sulfate, sodium olefin sulfonate and an animal protein foaming agent in a mass ratio of 5: (1-2): 3. The surface of the biomass material is activated by ammonium dihydrogen phosphate. The biomass porous concrete sound absorption material provided by the invention has the characteristics of low price, environmental protection, light weight, sound absorption, non-combustibility, simple process and the like, and can be used for sound barrier materials and wall sound insulation layers on traffic such as expressways, railways, subways and the like.

Description

technical field [0001] The invention relates to a biomass porous concrete sound-absorbing material and a preparation method thereof, belonging to the field of building materials and sound-absorbing materials. Background technique [0002] With the rapid development of modern industry and transportation construction, the noise problem is becoming more and more serious. Noise pollution has become one of the most serious environmental pollution problems affecting people's lives, and has become the main factor for urban residents' complaints. The main way to reduce noise pollution is to use porous sound-absorbing materials to absorb and reduce noise in the environment. Porous sound-absorbing materials mainly have the advantages of a structure with partly connected pores, high porosity, and sound-absorbing frequency bandwidth. Traditional sound-absorbing materials: organic sound-absorbing materials, such as plant fiber materials (sugar cane, straw, wood chips), foam, etc., have ...
