Envirocore cements reduce the CO2 intensity of cement while handling demanding infrastructure applications. Envirocore blended cement mixes combine Portland cement and supplementary cementitious materials (SCMs), resulting in strength and resistance to wear while lowering energy consumption. strengths are determined at different days of curing. In addition to this, sand is replaced with stone dust (SD) by 10%, 20% and 30% along with cement is replaced with MP by 0%, 10% and 20% by weight for M 30 grades of concrete. Only 3 cubes were casted for various percentage replacements of sand with SD and cement with MP for 7days and 28 days.Read More
Lesser Cement Consumption M-Sand is free of impurities such as clay, dust and silt and has denser particle packing than natural sand particles thereby reducing the voids in aggregate and hence saves cement requirement in concrete production. Vastu Friendly As per Vastu Shastra the construction material should be free from human or animal ... Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 124 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, 0.42 m 3 of sand and 0.83 m 3 of stone aggregate.Read More
Thus, the quantity of cement required for 1 cubic meter of concrete 0.98/0.1345 7.29 bags of cement. The quantities of materials for 1 m3 of concrete production can be calculated as follows The weight of cement required 7.29 x 50 364.5 kg. Weight of fine aggregate (sand) 1.5 x 364.5 546.75 kg. Mar 21, 2017 The construction of buildings, dams, roads, and bridges requires natural materials, primarily sand and gravel, crushed stone, cement, and iron and steel (Table 1). Natural aggregates include sand, gravel, and crushed stone. Aggregates are used in their natural state orRead More

This guide to CTB discusses its applications, benefits, design, construction, testing, and performance.Read More
Feb 16, 2020 RMC is ready-to-use concrete blend of cement, sand aggregate and water mixed in convenient proportion. It was first launched in Mumbai a few years ago Using moisture sensors to control slump in concrete production. Concrete has a worldwide consumption of approximately 1 tonne per person per year, making it the second most consumed substance on Earth after water. It is comprised of three elements aggregate and sand (filler), cement (binder) and water. When combined in the correct ratios ...Read More
