DIFFERENT TYPES OF CONCRETE STRENGTHS AND THEIR

2017-7-23 · Plasticisers – this makes the mixed concrete more workable and free-flowing. Ideal if it needs to be laid quickly. Fibres – these can increase the concrete’s strength and help prevent cracking. Retardants – these additives slow down the curing process of concrete, giving you more time to work. Accelerants – these additives speed up

CONCRETE Boral

2017-10-6 · Strength of concrete The compressive strength of concrete is measured by how much force is required to crush it, this is important in the design of structures. In pavements and other slabs on the ground, the design is usually based on flexural strength, (i.e.; how much force the concrete can withstand in bending before it breaks).
