in dry conditions), it should be suitable for use in concrete. Aggregates: Quality of aggregates, its size, shape, texture, strength etc determines the strength of concrete. The presence of salts (chlorides and sulphates), silt and clay also reduces the strength of concrete.

Nominal Mixes In the past the specifications for concrete prescribed the proportions of cement, fine and coarse aggregates. These mixes of fixed cement-aggregate ratio which ensures adequate strength are termed nominal mixes. These mixes are termed standard mixes.

Making the most of air entrained concrete. Air entraining agents (AEA) are used to entrain air in concrete when a structure will be exposed to moisture, freeze thaw cycles and deicing chemicals. Concrete is a porous material and water moves through these pores. Use appropriate mix designs and quality materials.

Monitoring mix design performance with an in-transit concrete management system. Ready mix concrete producers can optimize fleet processes and avoid overdesign—adding extra cement to the mix—by way of an in-transit concrete management system , which is installed on every ready-mix truck. The reason?
