Concrete bonding agents: why you need them,

22-09-2015  A bonding agent (bonding adhesive) needs to be painted onto the existing concrete first to ensure that the fresh concrete will successfully adhere. This is also true of floor repairs, if concrete is used to fill gaps caused by damage. The new won’t adhere to the old without the help of a

What are Concrete Additives? Why do we use

02-02-2018  These additives are used to introduce microscopic air bubbles to stabilize the concrete. The resultant effect is preventing the concrete from cracking in a cold environment. Air also raises the cohesion force thus reducing segregation and water bleeding before the concrete

Chemical Admixtures - Portland Cement Association

Retarders keep concrete workable during placement and delay the initial set of concrete. Most retarders also function as water reducers and may entrain some air in concrete. 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.

Red mud as an additive in concrete:

The current work investigates the sustainable use of red mud (RM) as a supplementary cementitious material in concrete. The large amount of RM produced by the alumina industry creates disposal problems, as RM pollutes the surrounding environment and leads to ecological imbalance. To develop suitable uses for RM, concrete in which some of the cement was replaced with RM was
