建筑垃圾界面膜化及掺量对混凝土抗冻性的影响

Effect of Interfacial Membranization and Content of Conctruction Waste on Frost Resistance

研究了不同的垃圾砂掺量和处理方式对混凝土抗冻性的影响.试验结果表明,用经过处理的垃圾砂制作的混凝土试块在抗冻性方面有提高,动弹模量可以提高10%以上,而质量损失明显减小.

This paper＇s main pourpose is to study the effect of different substitution rate and handling way on the frost resistance of recycled concrete.According to the experiment,the concrete made with the membernized construction waste has a rise in frost resistance,and it has a rise of 4% at most in dynamic elastic modulus and it has a evidence decrease in mass.
