建筑垃圾的处理及再生利用研究

在此对国内外建筑垃圾的现状进行了研究。对分选、破碎后的垃圾骨料进行了坚固性、压碎值等试验 ;将其替代新鲜石子做再生混凝土 ,并对再生混凝土的强度、弹性模量、抗冻、抗渗性能进行了试验。试验结果表明 ,强度损失很小 ,模量损失约 2 0 % ,抗冻指标 >D5 0。

RESEARCH ON TREATMENT AND REGENERATION OF BUILDING REFUSES

The present status of building refuses both at home and abroad is studied; the tests of soundness and crushing value etc of the separated and crushed refuse aggregate are also carried out,which can be used to replace fresh stone to make regenerative concrete,whose strength,elastic modulus,antifireeze and impermeability etc are tested.The test results shows that the strength loss is very small,while loss of modulus is about 20% and the antifireeze index>D50.
