2011/11/15Concrete mix ratios are the proportions of concrete components such as cement, sand, aggregates and water. These mix ratios are decided based on type of construction and mix designs. However, building codes provides nominal and standard concrete mix ratios for various construction works based on experience and testing.

Either of these ratios is used in mix design and considerably controls concrete strength. • Durability : Concrete must be able to endure severe weather conditions such as freezing and thawing, wetting and drying, heating and cooling, chemicals, deicing agents, and the like.

2020/7/8Concrete that is to be prestressed, pre-tensioned or heat cured should normally be specified as chloride class Cl0,10. Reinforced concrete should be specified as class Cl0,40 except for concrete made with cement conforming to BS 402710 (SRPC), which should be specified as class Cl0,20.
