Study on mechanical properties of high strength steel fiber reinforced lightweight aggregate concrete
ZHANG Ying
Abstract：Based on the orthogonal test,the influence of water cement ratio,nano SiO2content,aggregate type,and the content of fly ash on the compressive strength of lightweight aggregate concrete were conducted. The mix ratio of high strength lightweight aggregate concrete is optimized,and strength grade of LC40 won successfully. Based on the optimized mix ratio,the effect of differ-ent steel fiber volume fraction on the compressive,tensile and flexural strength of high strength lightweight aggregate concrete is further explored. The results show that the addition of steel fiber can improve the strength and ratio of tensile strength to compres-sive strength of high strength lightweight aggregate concrete and improve the brittleness of concrete.
