What is water cement ratio?

Mathematics

Water-cement ratio is the ration of mass of water to the mass of cement.
Numerically it is around 0.5, depending on the desired strength and workability.

A low ratio results in a dry mix which is difficult to compact, with a risk of developing voids in the final concrete.
A high ratio weakens the concrete, and is highly undesirable if strength is important.
To improve both the strength and workability of the concrete, sometime plasticizers are added.

It would have been appropriate to post this question in the Engineering section (if one is available).

Normally water cement ratio falls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 …. M25)

Can someone help me please.
zhannawk [14.2K]

Answer:

  1. Lena's Method: 280
  2. Jackson's Method: 280

Step-by-step explanation:

Lena's Method:

  1. 8 + 12 = 20
  2. Plug 20 in: 14(20)
  3. 14(20) = 14 × 20 = 280

Jackson's Method:

  1. 14 × 8 = 112
  2. 14 × 12 = 168
  3. Re-write the expression: 112 + 168
  4. 112 + 168 = 280

I hope this helps!
