What is the tonnes of sand required in one cubic metre of grade 25 concrete?

In grade 25 concrete, which typically has a mix ratio of 1:1:2 (cement:sand:aggregate), approximately 0.5 cubic metres of sand is required per cubic metre of concrete. Since the density of sand is about 1,600 kg per cubic metre, this translates to around 800 kg of sand needed for one cubic metre of grade 25 concrete. This amount can vary slightly based on the specific mix design and moisture content of the sand.

What is mean by m-25 grede conrete?

M-25 grade concrete refers to a specific mix of concrete that has a characteristic compressive strength of 25 megapascals (MPa) or approximately 3625 psi when tested at 28 days. The "M" stands for "mix," and the number indicates the strength of the concrete, which is achieved through a specific ratio of cement, sand, aggregate, and water. Typically, M-25 is used in structural applications such as beams, columns, and slabs where higher strength is required. This grade is commonly used in medium-strength construction projects.
