Additive Used In Concrete
Additives used in concrete there are several additives or admixtures used to change the composition of concrete or to accelerate or retard its hardening. the three commonly used are air-entraining agents, retarders, and accelerators. additives are not recommended if the end result can be reached more economically by altering the mix.

Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing, transporting, placing, and curing; and to overcome certain emergencies during concrete.
Chemical admixtures. chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete.
Concrete admixtures have various functions and they are as follows: (a) to increase the rate of strength development at early ages – calcium chloride is the most widely used accelerator, (c to increase the workability without changing the water content – pozzolana such as fly ash is used, (e) to increase the resistance to freezing and.

Concrete Mix Ratios
Concrete mix ratio of 1:3:3 – on mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of psi. on mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. the strength concrete is inversely proportional to the water/cement.
Utilization Of Crushed Clay Brick In Concrete Industry
Mar 01, clay brick powder was used as cement replacement and cement addition. the percentages used were 0%, 5%, 10%, 15%, 20% and 25% by weight of cement. on the other hand, concrete trial mixtures confirmed that the high water absorption rate of crushed clay brick adversely affected the workability of fresh.
