摘要
Abstract
The geopolymer stabilized recycled aggregate and cement stabilized recycled aggregate are prepared by the crushed powder,coarse aggregate,and fine aggregate of waste concrete.The engineering characteristics are compared and studied based on current specifications.The research results indicate that all the unconfined compres-sive strength,unconfined compressive rebound modulus,water stability,and shrinkage index of geopolymer stabi-lized recycled aggregates meet the relevant specifications.Under the same polymer and cement content,the me-chanical properties of cement stabilized recycled aggregate are better than those of polymer stabilized recycled ag-gregate;Both the water stability are the same;The dry shrinkage performance of geopolymer stabilized recycled ag-gregate is better than that of cement stabilized recycled aggregate.关键词
