Preparation Technology of Renewable Concrete under the Concept of Low Carbon and Energy Conservation
Propose the preparation technology of renewable concrete under the concept of low-carbon and energy-saving,this study designed different proportioning schemes,concrete specimens were prepared.In the application performance index testing of compressive strength and total cracking area,it was found that under four different nano SiO2 dosages(0%,0.5%,1.0%,1.5%),there are significant differences in the application performance of recycled concrete.The experimental results indicate that,1%nano-SiO2 mixed concrete specimen exhibits the highest compressive strength,meanwhile,the total cracking area per unit area reached the minimum value of 203.1mm2.To provide reference for improving the sustainability of building materials and promoting the application of renewable concrete.
