Frost Resistance and Pore Structure of Concrete Incorporated with Rubber Aggregates and Nano-SiO2

This paper aims to develop frost-resistant concretes, and investigate their pore structures and freeze–thaw damage mechanism. The frost-resistant concrete mixtures are designed by using rubber particles and nano-SiO2 to partially replace sands. The chord lengths, specific surface areas, contents and...
