Description
Summary:There is a wide variety of crop residues, and their application in concrete can promote green low-carbon development and environmental protection. By collecting and reviewing a large amount of relevant research literature from Chinese and foreign scholars, the effects on the mechanical properties and physical properties of concrete when coarse and fine aggregates or cementitious materials of concrete are replaced by crop residues such as coconut husk, corn, bagasse and rice are described. The leftover crop material was found to have wide applicability in concrete, enhancing the physical and mechanical properties of concrete and giving concrete its special properties of lightweight and heat retention. Finally, it points out the problems in the research of crop residues concrete, and puts forward the future research and development direction, looking forward to its application prospect, to provide a constructive reference for the development of low-carbon green concrete.
