Abstract: This study has investigated the effect of different sand granularity and also microsilice percents on the compressive strength of self-compacting cement composites’ matrix with high performance in laboratory. In this regard, 8 mixture designs were studied in order to obtain optimized granular martix and a more optimal mix design was selected in terms of compressive strenght. In order to achive optimal mix design, 8 test samples were developed by Taguchi algorithm and undergone compressive strength. The 8 samples from two basic design in 6 graularity factors were samples. In other 6 mix designs for optimal granularity, ratios 5, 10, 15, 20, 25 and 30% microsilice to cement were studied until the optimal matrix regrding compressive strength for using self compacting High Performane Fiber-Reinforced Cementitious Composites (HPFRCC) was determined. Then, 1 and 2% ribbed plastic fibre was added and compressive and tensile strength tests were conducted on these samples. In order to study the characteristics of fresh concrete including self-compact concrete flow, slump test and for transmission capapcity and self-compact concrete stability against separation, L-shape test was conducted. Results of this study showed that type of sand granularity has essential role in the tests of fresh concrete and compressive strength. Because of brittleness of matrix, addig fibres has high effect on the increase of compressive strength and prevention of brittle break out along with cracks due to not usig coarse grains and microsilice as a pozzolan and filling material has positive role for improving characteristics of this matrix.
