More DetailsBulking of sand – if the moisture is present in the sand, then it makes the sand look bulkier, which could result in inadequate sand proportion in the concrete ratio. if we need to add 1m 3 sand in the concrete mix ratio, we take 1.3 m 3 (30% more). the reason for that is the moisture content present in the sand makes it a little bulkier.
More DetailsC. [3]m. r. chitlange stated that “physical and chemical properties of quarry rock dust satisfied the requirements of code provision in properties studies. natural river sand, if replaced by hundred percent quarry rock dust from quarries, may sometimes give equal or better than the reference concrete made with natural sand, in terms of compressive and flexural strength studies.”
More DetailsConcrete is classified into different grades like m5, m7.5, m10, m15, m20 concrete based on the strength of concrete. in concrete grades, the letter “m” stands for “mix” (mix of sand, cement, and aggregate) and the following number stands for characteristic compressive strength of concrete in 28 days in the direct compression test.
More DetailsConcrete strength: higher concrete strength compared to river sand used for concreting. lesser concrete compared to m sand: silt content: zero silt: minimum permissible silt content is 3%. anything more than 3% is harmful to concrete durability. we can expect 5 – 20% slit content in medium quality river sand. over-sized materials: 0%.
