Effect on Macroscopic Properties and Value Analysis of Waste Glass Powder Replacing Cement of Foamed Concrete

In this paper, the effects of waste glass powder (WGP) as replacement of cementitious material on the compressive strength, dry density, shrinkage, softening coefficient of foamed concrete were studied. The results show that the compressive strength of foamed concrete with 0–30% amount of WGP admixture can be improved, and it reaches the maximum when the content is 20%. The addition of a certain proportion of WGP will reduce the shrinkage value and help to solve the problem of large shrinkage of foamed concrete. The addition of WGP can obviously improve the softening coefficient of foamed concrete, which is helpful for its application in wet or underwater environment. Finally, the value of WGP replacing part of cement in foamed concrete is analyzed, and the environmental protection and economy of WGP used in foamed concrete are proved quantitatively.
