Performance of shale powder in cement concrete

This article presents the performance of shale powder in cement concrete. The shale powder is used as additive for the concrete in the proportion of 0, 10, 20 and 30% by weight of cement. The concrete was tested under compression, split and flexural strengths. In all mixes manufacture sand used as fine aggregate and the mix was designed for M30 grade concrete. In addition to those mixes, with same grade of concrete, cubes, cylinder and beam specimens were prepared with natural sand and without shale powder. The test results of them consider for comparison purpose and also consider this as conventional or reference mix. From all the test results it is observed that, the mix with 10% of shale powder showed remarkable performance in compression, split and flexural strengths than conventional mix.
