at 0% to replacement to crushed sand in concrete mix. The result showed that 25% Replacement of crushed sand gives good compressive strength and by using crumb rubber up to 25% results in 8% decrease in density of concrete and ductility of concrete .

characterise the soils. Classification of the lateritic soil samples within Ota, revealed that the lateritic soils are mostly sandy clay of high plasticity and may replace sand by up to 20%, though an approximate linear decrease in strength with increasing sand replacement with lateritic soil was observed. This percentage replacement can be

Sand (primarily silica) is used in construction as a component in various materials like concrete, mortar etc. Definitely the salts adsorbed (dissolution might not actually occur) on sand are going to affect the durability in reinforced concrete...

The present study focused to use wood ash as a partial replacement for cement material during sand cement block manufacturing. The concrete mixtures have been mixed with 10%, 15% 20% and 25% of ...

After mixing, workability of the concrete was determined using slump test. It was confirmed that the slump values of concrete at different glass replacement level remained within the target slump range of 100–125 mm without changing the water content. The concrete was placed, compacted and surface finished with a smooth steel trowel in cube mold.

Concrete sand is and aggregate sand usually composed of either gneiss, trap rock, limestone or granite. This specific type of sand is normally crushed at the quarry and then washed and screened for quality.

For 5% red soil, the compressive strength and split tensile strength were decreased by 10.44% and 8.78% respectively in 28 days of curing, compared to plain concrete specimen. For 10% red soil ...
