| Abstract: | Wanzhou-Dazhou highway project is located in the sandstone area of Chongqing.How to use sandstone resources and engineering waste to reduce the cost has become one of the most attractive technical issues in highway construction in the mountain area.The influence of sandstone aggregate on the workability,mechanical properties and durability of low-grade concrete was studied.The result shows that the utilization of sandstone aggregate in low-grade concrete is available. |
