Concrete Mix Design Calculation for M40, M60 as per IS

Apr 18, 2019Concrete mix design calculation is all about finding perfect proportions of Cement, Sand and Aggregate to produce a good concrete to achieve its target strength. Here we described the full procedure of concrete mix design calculation and formula with ratio for M40 and M60 grade of concrete as per IS Codes and MORTH.

Lightweight concrete

Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3. Lightweight concrete can be specified using the notation LC for the strength class, e.g

What is Lightweight Concrete? (with pictures) wisegeek

Jun 19, 2019This lightweight concrete is often used in jobs requiring insulation from heat and sound. Structural lightweight aggregate concrete might typically require a density or unit weight of 90 to 115 lb/ft or (1440 to 1840 kg/m) and a compression rating of 2500 psi or (1700 MPa), which is about 65% of the density or unit weight of normal concrete.
