The w/c ratio is calculated from the weights of the materials, eg Concrete with 300kg of cement and 180 litres of water has a w/c ratio of 0.6 (i.e. 180÷300 = 0.6). What is the history of cement? The term 'cement' is used to describe a range of binding materials, the most common of which are known as hydraulic cements.

Use the chosen ingredients to calculate the ratio of cement, sand, and aggregate. For example, a common mix for general use is 1:2:3, which means one part cement, two parts sand, …
— In a mixing container, add no more than 1 part cement to 2 parts sand. For some applications, you may add up to a 1:8 ratio of cement to sand. More cement means more strength and stickiness but less workability. Ratios with more cement than a 1:2 ratio with sand will prove difficult to work with and some of the aggregate may not bind correctly.
