Understanding concrete admixtures corrosion inhibiting admixtures increase the passivation state of reinforcement and other embedded steel in concrete structures this can inhibit the corrosion process over extended periods when passivation would.
The general rule is that the more cement you have the stronger your concrete but too much cement also brings with it too much heat generated from hydration which will cause cracks and also retard the reaction the less water you have too the.
Retarders these reduce early strength gain but long term strength gain in increased accelerators these increase early strength gain but long term strength gain is reduced superplasticizers these reduce the water content of concrete which increases in.

Admixtures may enhance the durability workability or strength characteristics of a given concrete mixture admixtures are used to overcome difficult construction situations such as hot or cold weather placements pumping requirements early strength.
Retarding admixtures delay setting but not rate of strength development except early strength when long retardation is provided the effect of set retardation is assessed in terms of the time to develop a given degree of stiffness as indicated by the.
Accelerating admixtures increase the rate of early strength development reduce the time required for proper curing and protection and speed up the start of finishing operations accelerating admixtures are especially useful for modifying the properties.
To increasing the compressive strength of concrete we must increase cement and decrease water quantity for example m15 grade of concrete when we use50 kg of cement480 kg aggregates and32 liters water we get15nsqmm compressive strength after28 days.
Prestressed concrete is reinforced with prestressing tendons of tensioned steel rod or cable to increase its tensile strength precast concrete eg concrete blocks and masonry units are moulded and cured offsite then transported to the project.
