众所周知，再生骨料中有50%是细骨料，但其用途仍然有限。在这项研究工作中，分析了再生细集料在受控低强度材料(CLSM)生产中的应用。自密实流动CLSM材料由水泥、细骨料、水和引气剂组成。根据ASTM的最低要求和用天然细集料生产的CLSM所获得的结果，验证了用再生细集料生产的CLSM材料的合适配合比。还验证了所有含再生骨料的CLSM混合料在最佳配合比下的抗渗性和抗渗性，以及密度、孔隙率和硬化强度中的吸水性。
It is known that 50% of recycled aggregate is fine aggregate, however its use is still limited. In this research work the use of recycled fine aggregates for Controlled Low Strength Materials (CLSMs) production was analysed. Self-compacting and flowable CLSM material was composed of cement, fine aggregates, water and an air-entrained admixture. Adequate mix proportions of CLSM material produced with recycled fine aggregates were validated according to the minimum requirements of ASTM and the results obtained by CLSM produced with natural fine aggregates. Bleeding and penetration resistance for fresh state and density, porosity and absorption in hardened strength of optimum mix proportions of all CLSM mixtures with recycled aggregates were also validated.
