To determine the compressive strength of concrete specimens prepared and to . characteristic compressive strength (N/mm<sup>2</sup>) at 28 days. M15. 10. 15. M20.
and basalt concrete(M20 & M30).From this study it is estimated that onset onwards basalt concrete specimens increasing strength when compared to control.
observed that: (i). The compressive strength of OPC concrete at 7, 14 & 28 days is . ratio of fibres on compressive strength of SFRC Mixes of M20 & M50 Grade.
Thus, a concrete of M30 grade should attain a compressive strength of 30 . For example, M20 concrete is supposed to have a compressive strength of at least.
ers and pozzolona materials in the mix designs of high- performance concrete. Comprasion of Compressive Strength of M20 Grade. Fly Ash with Rice Husk Ash.
When cylinders were tested, the compressive strength for M15 and M20 mixes at 28 . Keywords: Roller compacted concrete, Compressive strength, Split tensile.
