Water Cement Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Water Cement Ratio = Weight of Mixing Water/Weight of Cementitious Materials
CW = w_m/w_c
This formula uses 3 Variables

Variables Used

Water Cement Ratio - Water Cement Ratio is the ratio of the weight of cement to the weight of water.
Weight of Mixing Water - (Measured in Kilogram) - Weight of Mixing Water is the weight of the water mixed in the batch.
Weight of Cementitious Materials - (Measured in Kilogram) - Weight of Cementitious Materials is the weight of cementitious materials mixed in the batch.

STEP 1: Convert Input(s) to Base Unit

Weight of Mixing Water: 9 Kilogram --> 9 Kilogram No Conversion Required
Weight of Cementitious Materials: 20 Kilogram --> 20 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

CW = w_m/w_c --> 9/20

Evaluating ... ...

CW = 0.45

STEP 3: Convert Result to Output's Unit

0.45 --> No Conversion Required

FINAL ANSWER

0.45 <-- Water Cement Ratio

Water Cement Ratio = Weight of Mixing Water/Weight of Cementitious Materials
CW = w_m/w_c

List the typical relationship between w/c ratio by weight and compressive strength of concrete.

The ACI code lists the typical relationship between the w/c ratio by weight and 28 days compressive streng.th of concrete as follows.
1. Non-air-entrained concrete (0.41 - 41 MPa) & (0.82 - 14 MPa)
2. Air-entrained concrete (0.40 - 34 MPa) & (0.74 - 14 MPa)
Further w/c ratio by weight varies from
0.67-0.38 for non-air-entrained concrete &
0.54-0.35 for air-entrained concrete when strength data are not available.

What is Water Cement Ratio & Cementitious Materials?

Water-Cement Ratio is defined as the ratio of the weight of water mixed in the batch to the weight of cementitious materials in the batch.
Cementitious materials indicate one of the principal ingredients that make up the concrete mixture. There are two types of cementitious materials: hydraulic cement and supplementary cementitious materials (SCMs). Hydraulic cement set and harden by reacting chemically with water.

How to Calculate Water Cement Ratio?

Water Cement Ratio calculator uses Water Cement Ratio = Weight of Mixing Water/Weight of Cementitious Materials to calculate the Water Cement Ratio, The Water Cement Ratio formula is defined as it is helpful in determining the ratio of the weight of water to the weight of cement that should be mixed in a batch of concrete to gain a specified strength. Water Cement Ratio is denoted by CW symbol.

How to calculate Water Cement Ratio using this online calculator? To use this online calculator for Water Cement Ratio, enter Weight of Mixing Water (w_m) & Weight of Cementitious Materials (w_c) and hit the calculate button. Here is how the Water Cement Ratio calculation can be explained with given input values -> 0.45 = 9/20.

FAQ

What is Water Cement Ratio?

The Water Cement Ratio formula is defined as it is helpful in determining the ratio of the weight of water to the weight of cement that should be mixed in a batch of concrete to gain a specified strength and is represented as CW = w_m/w_c or Water Cement Ratio = Weight of Mixing Water/Weight of Cementitious Materials. Weight of Mixing Water is the weight of the water mixed in the batch & Weight of Cementitious Materials is the weight of cementitious materials mixed in the batch.
