Concrete mixing process of rubber powder rough surface structure

Rubber powder has the role of air-entraining agents for rubber powder, rubber powder as dosage increases, the air content of concrete in varying degrees of increase, and were higher than the reference concrete containing gas
Volume. Precast concrete plant powder particles in the concrete mixing process, the rough surface of the rubber powder wrapped in a structure not only part of the water, but also a part of the air parcel, played a lead role in air, these air-stable presence in concrete. So rubber powder content, the more air entrainment is also greater. When the rubber powder content the same time, smaller particle size, rubber powder particle ready mix concrete plant part of the greater amount of space, the overall adsorption air is more, it also presents the gas content decreases with increasing particle size rubber powder big trend.
