6. For all structural elements, M25 grade concrete will be used. However, higher M30 grade concrete is used for central columns up to plinth, in ground floor and in the first floor. 7. Sizes of all columns in upper floors are kept the same; however, for columns up to plinth, sizes are increased. 8. The floor diaphragms are assumed to be rigid. 9.

Foam Concrete: A State-of-the-Art and State-of-the

Foam concrete (FC) has the potential of being an alternative to ordinary concrete, as it reduces dead loads on the structure and foundation, contributes to energy conservation, and lowers the cost of production and labor cost during the construction and transportation. The paper reports a state-of-the-art review of foam concrete in terms of its components, manufacturing and material properties

Comparative Study On RCC & Steel Building | PDF | Concrete

Grades of concrete: Concrete is known by its grade which is designated as M15, M20 etc. in which letter M refers to concrete mix and number 15, 20 denotes the specified compressive strength (fck) of 150mm cube at 28 days, expressed in N/mm2. Thus, concrete is known by its compressive strength.

Materials For High Density Concrete Production

To achieve the required concrete density to absorb the radiation a combination of high-density aggregates steel shot (fine aggregate) and hematite iron-ore (coarse aggregate) was used. The use of high density aggregates increased the cost for 40 Mpa concrete from approximately R370.00 to R7 600.00 per cubic metre of concrete in 1996. (A.
