在建筑材料排放量日益增加的背景下,将废玻璃及废弃黏土砖经过破碎、研磨、筛分后以连续级配作为粗骨料、细骨料、掺合料添加至再生混凝土的制备中,养护完成后测试各组试块的力学性能。分析掺合料对试件强度的影响时利用扫面电镜发现玻璃磨成微粉后棱角鲜明比砖粉更易于胶结,但试验中掺合料对试件的强度出现了抑制现象,主要原因是由于粒径为75μm微粉的微晶核效应较差。分析细玻（玻璃做细骨料）不同掺量对试件强度影响时利用水磨机切割观察切割面情况,细玻掺量越高切割面结构越致密且试件抗压强度与掺量比例成正相关,抗拉性能在取代率为30%时达到最大值,综合比较4种不同掺量得出,废玻璃作为细骨...

In the context of the increasing emission of building materials, after being broken, ground and sieved, waste glass and waste clay, by continuous grading, can be regarded as coarse aggregate, fine aggregate, and admixture to prepare recycled concrete.The mechani- cal property of every specimen will be tested after maintenance.Scan electron microscope（ SEM ） is used to analyze mineral admixture. Grinding the glasses into free power makes it angular and easy to cement but in this text mineral admixture draws supression phenomenon on specimen st...
