admixture on the dispersion of cement particles trapping the mix water Water reducing admixtures are based on modified lignosulfonic acid derivatives, hydroxycarboxylic acids or hydroxylated polymers. It is important to remember that the addition of an admixture can have secondary effects, which may be beneficial or detrimental.
Rescon T® is an anti-washout admixture in powder form, for use with under water concrete and mortar. PROPERTIES Addition of Rescon T® makes concrete suitable for all types of underwater applications: • The cohesiveness of the concrete increases which prevents washout of cement, and does not cloud the water and reduce visibility during placement
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.
