The effect of nano-SiO2 on concrete properties: a review
In recent years, the addition of nanometer materials to concrete materials has attracted a group of increasing number of scholars' research interests, and nano-SiO2 is one of the research hotspots. In this paper, we briefly introduce the influence of nano-SiO2 on setting time, slump, shrinkage, durability and mechanical properties of concrete. In addition, this review also includes the microstructure measured by scanning electron microscope (SEM) and the content of various hydration productsdoi:10.1515/ntrev-2019-0050 fatcat:3ndh7f6jyral5hcv4wssp7xiu4
