Study on the Performance of Pumice-Straw Composite Concrete

Abstract:

A new kind of concrete was made by the combination of corn stalks which is the main crop in northern China,natural pumice resources and cement. The results show that wrapped cover pretreatment technology can not only greatly reduce the water absorption of pumice and stalks, but also effectively plug up sugars in the corn stalks,which is advantageous to the formation of hardened concrete. The incorporation of the stalks can reduce the apparent density and thermal conductivity of the concrete. The composite concrete characterized by energy-saving and environment protection is worth popularizing.
