Waste rubber powder mixed model steel fiber reinforced lightweight aggregate concrete and preparation method thereof
The invention relates to concrete and a preparation method, in particular to Waste rubber powder mixed model steel fiber reinforced lightweight aggregate concrete and preparation method thereof. The concrete per cubic meter is made of raw materials comprising, by weight, 14%-25% of cement, 0.1%-0.6% of model steel fibers, 0.03%-1.75% of rubber powder, 22%-45% of fine sand, 27%-50% of fly ash ceramsite, 6%-12.9% of net water content and 0%-0.03% of water reducing agents. The old rubber powder and the model steel fibers are mixed into the lightweight aggregate concrete, so that performance advantages of two kinds of materials can be given to full play, on the other hand, the old rubber powder is added in the model steel fiber reinforced lightweight aggregate concrete, vibration energy can be more effectively absorbed, impact performance and bend toughness of the lightweight aggregate concrete can be enhanced remarkably, and meanwhile, frost resistance, corrosion resistance and abrasion resistance of the model steel fiber reinforced lightweight aggregate concrete can be improved.
