Jul 01, 1996 · Once the effects of crushed stone dust on concrete properties are obtained, it will be possible to take necessary measures to alleviate its adverse effects on concrete. Experimental Program Materials. In all mixes limestone crushed rock coarse and fine aggregates were used. Dust passing 75 um BS sieve was produced in a laboratory crusher

investigation on the flexural behaviour of high

Jul 01, 2007 · Crushed sandstone sand appears in angular shape and rough surface and it exhibits better mechanical interlocking with cement paste thus improving compressive strength. Recently in a research of HPC, it was shown that up to 40% of river sand can be replaced effectively by crushed sandstone sand without compromising quality

Sep 01, 2016 · Several studies have been conducted in the past to investigate the effect of partial replacement of Natural River sand with crushed rock sand. Celik and Marar (1996) concluded that partial replacement upto 30% leads to decrease in slump value. However, a significant improvement in the compressive, flexural strength and impact resistance was observed

Jun 29, 2006 · Aggregates are the major constituents in the construction industry. With natural sand and gravel resources being rapidly depleted all over the world, the needs of construction industry will have to be met increasingly from crushed sand as fine aggregates. This paper presents results of the laboratory investigation on high performance concrete (HPC) using crushed sandstone sand …

Dec 01, 2016 · This research consists of incorporating the crushed sand (CS) in the composition of a concrete and studies the effect of its gradual replacement by the sand dune (SD) on sustainability of high performance concrete (HPC) in aggressive environments. The experimental study shows that the parameters of workability of HPC are improved when the CS is partially …

Jan 18, 2020 · Yang et al. investigated the physical and mechanical properties and permeability of sandstone after high-temperature treatment and found that a critical temperature for the physical and mechanical properties exists at 400–500 °C. The physical properties (i.e., weight, density, P wave velocity, and S wave velocity) decreased with increasing temperature after the critical temperature, while the initial permeability of the sandstone …

Aug 14, 2019 · It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. More precisely, sand is between 1/16 millimeter and 2 mm in size (silt is finer and gravel is coarser). The sand grains that makeup sandstone are aptly referred to as framework grains
