Concrete Admixture Solutions. Retarders delay the hydration of cement particles thus allowing for extended workability of the concrete. Retarder are typically . Concrete Additives Nation's Equipment Sales. Concrete additives can assist in a variety of ways to improve your concrete batches.
Concrete and plaster admixtures as both retardant and plasticizer, by reducing water content to the mixture. It also can be used as water reducing agent and retarder in the building industry. Sodium gluconate is also an efficient set retarder and a good plasticiser water reducer for concrete, cement, mortar and gypsum.
Retarders are beneficially used in hot weather conditions in order to overcome accelerating effects of higher temperatures and large masses of concrete on concrete setting time. Because most retarders also act as water reducers, they are frequently called waterreducing retarders.
Superplasticizers (SP) and retarders are important to enhance the workability and setting time of concrete under hot weather, hence, an experimental investigation was conducted to determine the optimum dosage for the admixtures and to study the effect of over dosage of the mentioned admixtures.
Permacolour offer a range of Concrete Additives and admixtures. From plasticisers and efflorescence reducers to curing agents and retarders.
Inorganic compounds, commonly used as cement retarders, are borax (Na 2 B 4 O 7 •10H 2) and other borates such as boric acid (H 3 BO 3) and its sodium salt and zinc oxide (ZnO). Borates are commonly used as a retarder aid for hightemperature retarders at BHCT of 300°F (149°C) and greater.

Concrete Retarder. Concrete retarders are a chemical solution designed to slow down curing process in the cement. Concrete Retarders are typically used to prevent the chemical hardening of the surfacing of the concrete, allowing the cement to be washed off the following day to expose the aggregate. For more information on concrete retarders...
Xypex Additive. Xypex Additive products, added to the concrete at time of batching, are part of the Xypex concrete waterproofing and protection system and represent one of three different ways to install Xypex Crystalline Technology into concrete.
Saves time. Top surface retarder for new sidewalks, driveways, construction joints, and other faceup exposed aggregate concrete applications. Heavy bodied, pigmented, waterbased retarder. Recommended for use on top surfaces, or as a form retarder on flat panels, ICF formliners or construction joints (9).
Retarders: A retarder used to slows down the process of hydration so that concrete remains plastic and workable for a longer time. (ex: gypsum,sugar etc) Accelerator: These are added to concrete to increase the rate of early strength to permit earlier removal of formwork (ex: calcium chloride)
