Research on the Influence of Aggregate Content on the Abrasion Resistance of High Performance Concrete
摘要
Performance tests were conducted on high abrasion resistance concrete with different coarse aggregate contents and sand replacement rates. The influence of aggregate content on the slump, compressive strength, and impact and wear resistance of concrete was analyzed. The results show that when the ratio of slurry to aggregate is 5:5, the slump and abrasion resistance strength of high abrasion resistance concrete decrease with the increase of sand replacement rate, while the compressive strength increases with the increase of sand replacement rate. At a ratio of 5:5–5, the abrasion resistance of hydraulic concrete reaches its optimal performance.
