It's advisable to use a small barrel or other large container to hold water if you're doing several mixes.

A sheet of plastic or large wooden board such as a sheet of plywood keeps the ground clean and prevents contamination of the materials by soil and dirt.

Measure out the stone, sand and cement into 3 separate piles on the ground.

You can make the mix stronger by reducing the amount of stone to 3 buckets (C30 mix).

1 bucket of cement, 2 buckets of sand and 4 buckets of stone, this will produce about a wheelbarrow full of concrete. A small Belle mixer such as the Minimix 130 or Minimix 150 will mix about 90 litres of concrete, so if you do a C20 mix, i.e.These are convenient for measuring out quantities of materials before mixing commences. A UK builders bucket will typically hold 3 UK gallons or 13.5 litres.

Here are some tips to get the best results.

Steps on How to Use a Cement MixerДЄ cement mixer allows you to mix concrete quickly and you can produce a wheelbarrow of concrete in about 10 minutes. Read the safety information on bags of cement. Steel toe cap shoes/boots for foot protection.Safety glasses to protect your eyes from splashes from the mixer.

Gloves to protect your hands from abrasion and cement which is an irritant and somewhat caustic.

Stone and sand can be wet, so using a separate bucket for cement keeps it dry and stops cement sticking to the sides. Too much water is also detrimental to the final strength because as excess water that doesn't combine with cement evaporates, it leaves behind micropores which are tiny air cavities. Concrete that is too dry is unworkable and also won't have sufficient water for the chemical reaction with cement to progress properly and the concrete to cure, therefore reducing its ultimate strength. A shovelful deposited on the ground should self-support itself without spreading out (slumping). So if we have 1 bucket of cement, it takes 1.5 buckets of water to weigh the same amount and again taking a figure of 0.5, we need 0.5 x 1.5 = 0.75 or 3/4 buckets of water per bucket of cement.Д¬oncrete shouldn't be excessively wet after mixing and should have minimum slump. Loose cement has a density of about 1.5 kg/litre. Now since 1 kg of water has a volume of 1 litre, this equates to 12.5 litres of water for 25 kg of cement.ДЎ2.5 litres is nearly 2 3/4 imperial (UK) gallons or 3.3 US gallons. For a 25kg (4 stone approx) bag, if we take a figure of 0.5 this works out at: The quantity of water needed should be 0.4 to 0.6 times the weight of cement.

Ideally it must only be wet enough so that it's workable. The drier concrete is, the stronger it is. Quantity of Water Needed When Mixing Concrete This is mixed 1 part cement, 3 parts stone and 2 parts sand. This is mixed 1 part cement, 4 parts stone and 2 parts sand.Д¬30 is a stronger mix suitable for thinner and narrower concrete slabs, e.g.
