Research on High-Absorbency Resin Concrete Based on Mix Proportion Optimization
In order to investigate the influence of high water-absorbent resin on the strength and workability of con-crete,four sets of experiments are designed to study its strength characteristics and workability.The results show that the addition of high water-absorbent resin reduces the strength of concrete by 10%～20%.The slump and slump flow of fresh concrete decrease rapidly as time goes on,with a slump loss of 20%at 30 minutes and a slump flow loss of approxi-mately 50%at 60 minutes.The optimal addition amount of high water-absorbent resin is 0.3%.Microspheres can reduce the strength and workability losses caused by the addition of highly absorbent resins in concrete.They can be used in conjunction with highly absorbent resins in engineering applications.The research findings of the study can provide a cer-tain reference basis for practical engineering.
