Method for regenerating aggregate concrete from steel fibre rubber granule modified asphalt

The invention discloses a method for preparing steel fiber rubber particle modified asphalt recycled aggregate concrete. In the method, waste concrete is subjected to crushing, separating, screening, washing and drying to obtain the recycled aggregate, and the recycled aggregate is stirred with emulsified asphalt until the emulsified asphalt is covered on the surface of the recycled aggregate; waste tire is subjected to coarse crushing, separating, washing and drying to obtain the steel fiber rubber particle; and the recycled aggregate containing the emulsified asphalt, steel fiber rubber particles, natural aggregate, cement, sand and water are stirred according to certain ratio to obtain the steel fiber rubber particle modified asphalt recycled aggregate concrete. In the invention, the waste tire is subjected to crushing process to produce the steel fiber rubber, and the crack resistance, the heat preservation capability and the energy absorption and noise reduction capability of the asphalt recycled aggregate concrete are effectively improved by the modification of the steel fiber rubber; and the material is a circular economy building material, and by producing the material, the environmental pollution is reduced, and the performance of the material can be improved under the condition of not increasing cost.

InactiveCN106894645AIncrease cross-sectional contact areaReduce additional costsBuilding repairsRebarReinforced concrete
The invention relates to the field of civil engineering, in particular to a novel FRP profile chamfering block and its application. The chamfering block includes a cylindrical body, the body is axially provided with a right-angle groove through the body, the two right-angle faces of the right-angle groove extend outside the body, and transition sections are filled between the body and the two right-angle surfaces of the right-angle groove, , right-angle groove and transition section are integrally formed, and the material is FRP. The present invention also provides a reinforcement method for reinforced concrete rectangular columns, namely: paste the right-angled grooves of the FRP profile chamfering blocks on the corners of the rectangular columns from top to bottom along the height of the column, and between adjacent chamfering blocks in the horizontal direction The gap between them is filled with epoxy resin, and then the chamfering block is wrapped with FRP cloth. With this chamfering block, the rectangular column no longer needs to be chamfered during reinforcement, which fundamentally solves the difficulty of chamfering the rectangular column, greatly reducing the extra cost of reinforcement; and solves the FRP caused by the stress concentration of the chamfering Problem with cloth being pulled off prematurely.
