Example 2 : Design a concrete mix to implement a concrete slab (exposed to sever conditions moisture and freezing and thawing) with design compressive strength 30 MPa, a standard deviation equals to 4 and the percentage expected less than minimum strength is 10%. Sulphate Resisting Portland Cement is used. The maximum size of an angular aggregate is 20 mm with apparent density 1500 kg/m3. The available fine aggregate has fineness modulus 2.4 An air entraining agent has been used in the mix.

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.
