What is grade 35A for concrete is?

Answer 1

Grade 35A concrete refers to a specific concrete mix that has a characteristic compressive strength of 35 megapascals (MPa) when tested at 28 days. The "A" typically indicates that the concrete meets specific performance criteria, such as workability or durability, suitable for various construction applications. This grade is commonly used in structural applications like beams, slabs, and columns where moderate strength is required. The mix design often includes a combination of cement, aggregates, water, and admixtures to achieve the desired properties.
