Grade 35 refers to a specific classification of concrete strength, indicating that the concrete can withstand a compressive strength of 35 megapascals (MPa) when tested at 28 days. This grade is commonly used in construction for structural elements like beams, columns, and slabs, providing a balance between strength and workability. In many regions, Grade 35 concrete is often used in residential and commercial buildings, as it offers durability and resistance to various environmental factors. It is typically mixed with aggregates, cement, and water, following standards set by organizations such as ASTM or BSI to ensure quality and performance.
