Since most chemical admixtures perform well in plain Portland cement mixtures and in Portland cement and fly ash concrete, it is not surprising that they provide similar performance when used in slag concrete. Since there is little or no carbon in GGBFS, concrete …

Admixture of concrete 1. PRESENTED BY K.LAVANYA,M.Tech 1 2. Admixtures is defined as a material, other than, Cement Water Aggregate That is used as an ingredient of concrete and is added to the batch immediately before or during mixing. Admixtures are used to modify the properties of ordinary concrete so as to make it more suitable for any situation. 2

Curing agents. Liquid curing agents such as Sika® Antisol® E-20 can be sprayed onto the concrete surface with simple tools (e.g. low pressure, garden type sprayers). They must be applied over the whole surface as early as possible.

Concrete Additives. In the construction industry our additives are used to reduce the cost of concrete construction, to optimize concrete properties and to ensure reliable and consistent quality of concrete. With our long-standing expertise in surfactant technology, we developed tailor-made solutions for the admixture market.

Early curing of your concrete's fresh surface is essential to ensuring its long-lasting endurance against the ravages of time. Our ready-to-use Emcoril curing agents can be relied upon to create an effective liquid membrane to extend the hydration time of your concrete. They form an impervious, continuous film to keep the moisture in.

Concrete admixtures： Adhesive bonding admixture. Concrete interface agent is a polymer-modified cement mortar, which can enhance the adhesion to the base layer, has good water resistance, damp heat resistance, freeze-thaw resistance, and avoids the hollowing and shelling of the plaster layer. Manual chiseling process saves time and effort.

CHRYSO®Fuge B renders mortar and concrete highly resistant to capillary action and reduces, or even eliminates, infiltration of water under pressure. CHRYSO®CWA 10 – Crystalline waterproofing admixture. Active ingredients of CHRYSO®CWA 10 react with moisture to form crystals deep within the pores and capillary tract of the concrete structure.

The mixing process of admixture in concrete: Admixtures have to be mixed before mixing the concrete i.e. when we are adding all the required ingredients for concrete or admixtures has to be mixed during the mixing process of concrete i.e. when we start the mixer. It has to be mixed slowly when the mixing process is going on.
