摘要：
In this paper, the impact strength of four concrete mixtures namely green high performance plain concrete (GHPPC), green high performance and steel fibre reinforced concrete (GHPSFRC) subjected to drop weight test was statistically investigated. The steel was incorporated each at a dosage of 0.5%. The pre-determined green concrete mixtures were prepared with 2% of nano silica as cement replacement and 30% of copper slag as fine aggregate replacement. From each type, 40 specimens were tested using the drop weight test in accordance with procedure proposed by ACI Committee 544 and their impact strength was determined. Results showed that the distribution of impact strength of GHPPC and GHPSFRC were approximately normal. The minimum number of tests necessary for attaining the impact failure strength of, GHPPC and GHPSFRC specimens were found to be 57 and 41 respectively at 95% level of confidence with an error below 10%.
