what are the concrete additives?
Chemical admixtures are important ingredients that need to be added to the concrete mix other than cement, sand and aggregates. The admixture is added before or during the mixing process.
Concrete producers use admixtures primarily to modify the properties of hardened concrete; to ensure the quality of concrete during mixing, transporting, placing, curing; and also to reduce the costs of concrete.
Admixtures are added to concrete batch immediately before or during mixing concrete. Concrete admixtures can improve concrete quality, manageability, acceleration or retardation of setting time among other properties that could be altered to get specific results.
SET RETARDING ADMIXTURE
Set retarding concrete admixtures are used to delay the chemical reaction that takes place when the concrete starts the setting process. These types of concrete admixtures are commonly used to reduce the effect of high temperatures that could produce a faster initial setting of concrete. Set retarding admixtures are used in concrete pavement construction, allowing more time for finishing concrete pavements, reducing additional costs to place a new concrete batch plant on the job site and helps eliminate cold joints in concrete. Retarders can also be used to resist cracking due to form deflection that can occur when horizontal slabs are placed in sections. Most retarders also function as water reducers and may entrain some air in concrete.
AIR ENTERTAINMENT ADMIXTURE
This type of admixture produces a more workable concrete than non-entrained concrete while reducing bleeding and segregation of fresh concrete
WATER REDUCING ADMIXTURES
Water-reducing admixtures are used to obtain specific concrete strength using lower cement content. With this type of admixture, concrete properties are improved and help place concrete under difficult conditions.
Accelerating concrete admixtures are used to increase the rate of concrete strength development or to reduce concrete setting time.
The main purpose of using superplasticizers is to produce flowing concrete with a high slump in the range of seven to nine inches to be used in heavily reinforced structures and in placements where adequate consolidation by vibration cannot be readily achieved.
CORROSION - INHIBITING ADMIXTURES
Corrosion-inhibiting admixtures fall into the specialty admixture category and are used to slow corrosion of reinforcing steel in concrete. Corrosion inhibitors can significantly reduce maintenance costs of reinforced concrete structures throughout a typical service life of 30 – 40 years. Corrosion-inhibiting admixtures have little effect on strength at later ages but may accelerate early strength development. Calcium nitrite based corrosion inhibitors do accelerate the setting times of concretes over a range of curing temperatures unless they are formulated with a set retarder to offset the accelerating effect.
