Chemical admixtures should be added in accordance with the manufacturer’s technical data sheets. The dosage of most chemical admixtures is mix design specific and should be evaluated prior to use. Some chemical admixtures are designed to allow for an extended setcontrol of the freshly mixed concrete. Chemical admixtures are the ingredients in concrete other than portland cement, water, and aggregate that are added to the mix immediately before or during mixing. Producers use admixtures primarily to reduce the cost of concrete construction; to modify the properties of hardened concrete; to ensure the quality of concrete during mixing. CIP 15 - Chemical Admixtures for Concrete WHAT are Admixtures? Admixtures are natural or manufactured chemicals which are added to the concrete before or during mix-ing. The most often used admixtures are air-entraining agents, water reducers, water-reducing retarders and accelerators. WHY Use Admixtures? Chemical Admixtures for Concrete surveys recent developments in admixture technology, explaining the mechanisms by which admixtures produce their effects, the various types of admixtures available, their selection and use. Because of the economies they can offer, admixtures are being used increasingly in civil engineering projects worldwide.

There is no rocket science in Mineral Admixtures (i.e. They are straight forward like Fly Ash, GGBFS, Micro Silica etc. “Chemical Admixtures” on the other hand are used under mult. Admixtures of concrete are generally used to alter the properties of concrete (such as increased workability or reduced water content, acceleration or retardation of setting time, acceleration of strength development, and improved resistance to weather and chemical attacks) to make it more suitable for a particular purpose. For example, calcium. Science and Technology of Concrete Admixtures presents admixtures from both a theoretical and practical point-of-view. The authors emphasize key concepts that can be used to better understand the working mechanisms of these products by presenting a concise overview on the fundamental behavior of Portland cement and hydraulic binders as well as their chemical admixtures, also discussing recent.
