Review of research on durability of reactive powder concrete

Abstract

Insufficient durability is an important reason why sustainable concrete materials cannot be achieved. Reactive Powder concrete (RPC) has attracted wide attention of researchers due to its excellent durability. Therefore, a series of researches on the durability of RPC have been carried out in order to achieve sustainable development of concrete. Therefore, based on the research results of domestic and foreign scholars, the durability of reactive powder concrete is comprehensively discussed from two aspects: single factor effect and multi-factor coupling effect. Judging from the research results, whether under the action of single factor or multifactor coupling, reactive powder concrete has shown extraordinary durability performance, which proves its feasibility in creating durable concrete engineering; By summing up the existing research results, we also found its shortcomings, mainly including the lack of research on multi-factor coupling effects, especially the load-environment coupling effects, the lack of a micro-level description of the damage process, and the damage theory model is not yet clear, Evaluation methods, indicators are still to be studied and lack of actual data support and other issues.
