The net cost of Concrete reduces when FM of sand increases. It reduces by about 6.5% for an increase of FM from 2.0 to 3.0. As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This is 29% when FM changes from 2.0 to 3.0. That means we can get large advantage by using concrete having Coarse Sand.

We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting. In this post, we are going to explain that in detail. Grades of Concrete Actually, what do we mean by grade of concrete.? Concrete grades are […]
Flexural strength, shear strength and deflection are critical to the design of lintels. Because of their rigidity, strength, durability, fire resistance and aesthetics, the most common types of lintels for concrete masonry construction are those manufactured of precast reinforced concrete or reinforced concrete masonry units.
