Different admixtures are studied. The results show that the strength of hardened cement mortar with admixtures is higher than that without admixtures. For the mixture of 80% fine building waste and 20% cement, 1.5% Na2SO4 (in weight) is most effective to increase strength.展开更多

The basic framework of the integrated building waste management, including control of the sources, reduction of the integrated process and final disposal, are proposed in view of the problems existing in recovery of the building wastes and the experiences from the developed countries.展开更多
