Cement Admixture - an overview | ScienceDirect Topics

Modern concrete very often contains two or more chemical admixtures in order to improve its fresh and/or its hardened properties. Besides admixture–cement interactions examined in the previous sections, it is also important to master possible problems due to admixture–admixture interactions and incompatibilities.

Cement plasticizers are chemicals to be added in cement – concrete mixture. It is to be added in proportion of 0.1% to 0.4% by wt. of cement. It means in 50 Kg of cement bag, 250 gm to 400 gm of chemical has to be add. Addition of these doses reduces 5% to 15% of water requirement in the concrete mix with constant workability.

Types of Admixtures of Concrete & Cement | Chemical, …

An addition for hydraulic cement or an admixture for concrete or mortar which causes air, usually in small quantity, to be incorporated in the form of minute bubbles in the concrete or mortar during mixing, usually to increase its workability and frost resistance. Air-entraining admixtures are surfactants that change the surface tension of the water.

26-09-2018· Gas forming admixtures are also used to prepare light weight concrete. For settlement and bleeding resistance purpose, small quantity of gas forming admixtures which is generally 0.5 to 2% by weight of cement is used. But for making light weight concrete larger quantity generally 100 grams per bag of cement is recommended. 8. Air detraining Admixtures

Concrete - Wikipedia

Concrete is a composite material, comprising a matrix of aggregate (typically a rocky material) and a binder (typically Portland cement or asphalt), which holds the matrix together. Many types of concrete are available, determined by the formulations of binders and the types of aggregate used to suit the application for the material. These variables determine strength, density, as well as chemical and thermal resistance of the finished product.

Concrete - Wikipedia

Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual ...

Retarding Admixture - an overview | ScienceDirect Topics

These admixtures influence both the dispersion of the cement in the presence of water, and the hydration rate of single cement phases, becoming the most used water-reducing/ retarding admixtures in the concrete industry (Danner et al., 2015). The source of the admixture is lignin, a biopolymer contained at 20–30 wt% in wood (Plank, 2004).
