2014-01-31· Following on from the previous blog, which explored the key materials that form concrete, this blog explores additives and admixtures. These are materials and chemicals that come in powder and liquid form. They are added to a concrete mix to alter its properties and to give it certain characteristics not obtainable with plain concrete mixes. …

Use of Water Reducers, Retarders, and Superplasticizers. Introduction. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality. An increase in paste quality will yield higher compressive and ...

OsmoPhob-Additives make it possible to produce concrete goods, i.e. cement-bound construction materials in general and in particular high-quality face concretes, with significantly reduced water absorbency. Plasticizing properties increase the density of wet concrete. Concrete compaction becomes easier and the concrete more homogenous, for more even surfaces. The diffusivity of building ...

These are additives used for watertight concrete, and their task is to reduce the capillary absorption of the concrete mix by blocking the capillary pores. Waterproofing admixtures make it possible to obtain concrete surfaces that are resistant to water and to aggressive chemical agents. Some of them also work well as anti-frost admixtures for concrete. They reduce the
