Question

The expected out turn of cement concrete for 1 : 2 : 4 per mason per day is 5.

(a) True

(b) False

The question was asked by my school teacher while I was bunking the class.

My doubt stems from Labour Rates for Workers topic in chapter Schedule of Rates Metric and F.B of Civil Engineering Drawing

Answer 1

Correct choice is (a) True

The explanation is: For 1 : 2 : 4 concrete, 1m^3 need Labour constant.

Mixing concrete = 3.00 hour/m^3.

Lifting and carrying concrete = 1.20 hour/m^3.

Compacting concrete = 0.80 hour/m^3.

Levelling surface of concrete = 0.10 hour/m^3.

Total= (3+1.2+0.8+0.1) = 5.
