|The strength of concrete is determined by using Flexural test and strength test of M40 concrete. Compressive strength, Flexural strength, Split tensile strength and Alkalinity test of concrete mixes made with using different dust material , sand and 4.75mm down basalt have determined at 7 & 28 days. The compressive and flexural strength have determined of 15%, 20% and 50% in added M40 concrete. Results shows that the increase 15% and 25%compressive strength of the cement is high as compare to M40 cement concrete. The compressive &flexural strength also determine for M40 with mix sand basalt stone, 15%, 20%, 50% sand replacement
The results clear indicate the compressive strength of the 28 days material is higher as compare to 7 days material. We can say that age of concert. Figure shows that the M40 with concrete with granite dust compressive strength for the 7 & 28 days. The results clear indicate the strength of the Sample-3, 25% is higher than the 15% and 50%. But as compare to beam not follow.
