| Abstract: | With the development of infrastructure in China and promotion of the “Belt and Road” initiative,the traditional mineral admixture is gradually becoming scarce,and the rock powder,a manufactured sand byproduct,can be a good complement to it.This paper looks at relevant literatures and standards at home and abroad,systematically summarizes the influence of rock powder as mineral admixture on concrete performance,and examines standard specifications and intellectual property rights of rock powder as mineral admixture at home and abroad.It also looks into the shortcomings of current research in this field,and points out the direction of future research accordingly. |
