Design concrete mix to satisfy the requirements for concrete foundation subjected to ground water with high concentrations of sulfates. The mean compressive strength is 25 MPa with slump of 80-100 mm. Thickness of the foundation is 37.5 mm. The dry-rodded unit weight of coarse aggregate is 1650 kg/m3. The fineness modulus of fine aggregate is 2.4. The specific gravity (SSD) for fine and coarse aggregates is 2.6 and 2.7 respectively. The moisture content of fine and coarse aggregate is 6% and 2% respectively. The absorption of coarse and fine aggregate is 0.5% and 0.9% respectively. Note: use volume method when it is required.

Types of Concrete

Concrete is the fundamental material used in civil engineering such as building materials for building structures. Concrete is an aggregate mixture of cement, sand, and fine and coarse rock pieces. The cement acts as a binding material that holds the compositions together, sets, and hardens with time. Apart from cement, there are other different types of binding materials used, such as lime concrete, bitumen, asphalt, and so on.
