How to mix cement (for garden projects

6 x 25kg bags of cement (get the plastic wrapped bags, the paper ones often split or get wet) 1 x 1000kg (850kg if they have it) builders sand Mixing the cement. Before you begin to mix it's a good idea to plan your mixing station. Concrete has a habit of ending up all over the place so make sure you mix somewhere this doesn't matter.

TIP 10 - Mixing Water Quality for Concrete

Water is an important constituent in concrete. It chemically reacts with cement (hydration) to produce the desired properties of concrete. Mixing water is the quantity of water that comes in contact with cement, impacts slump of concrete and is used to determine the water to cementitious materials ratio (w/cm) of the concrete mixture.
