Various types of admixtures are used in concrete to enhance the performance of concrete. Concrete admixture is defined as the material other than the aggregate, water and cement added to the concrete. Water reducing admixtures, the name itself defining that they are used to minimize the water demand
A material other than water, aggregates, or cement that is used as an ingredient of concrete or mortar to control setting and early hardening, workability, or to provide additional cementing properties. Admixtures are generally used to alter the properties of concrete (such as increased workability or reduced water content, acceleration or retardation of setting time,
Dec 01, 2016 Admixtures: Admixtures are the special ingredients added during concrete mixing to enhance the properties and performance of fresh concrete. Various types of admixtures are available in the market which is used in construction work.

Before going to mineral admixtures, I will clarify the difference between admixtures and additives Concrete admixtures vs additives: Anything which is added during grinding stage which has some special effect on fresh and hardened properties of concrete while on the other hand admixture 
Dec 01, 2016 Admixtures are the special ingredients added during concrete mixing to enhance the properties and performance of fresh concrete. Various types of admixtures are available in the market which is used in construction work. Function Of Admixtures: 1. To accelerate or retard the setting time of fresh concrete.
Admixtures are used in concrete to alter its properties in various ways. Some common uses include improving workability, increasing or decreasing cure time, and increasing concrete strength. Admixtures can also be used for aesthetic reasons, such as to change the color of the cement.
Admixtures for Concrete Fig. 6-1. Liquid admixtures, from left to right: antiwashout admixture, shrinkage reducer, water reducer, foaming agent, corrosion inhibitor, and air-entraining admixture. (69795) Despite these considerations, it should be borne in mind that no admixture of any type
Apr 26, 2016 Types of Chemical Admixtures for Concrete. Unlike mineral admixtures, which may be introduced as blended cements, chemical admixtures are typically added during the mixing process of concrete production. Depending upon the requirement, different types of chemical admixtures are manufactured such as air-entraining admixtures, accelerating
The most common admixtures are retarders and accelerators. In normal use, admixture dosages are less than 5% by mass of cement and are added to the concrete at the time of batching/mixing. (See § Production below.) The common types of admixtures are as follows: Accelerators speed up the hydration (hardening) of the concrete.
Corrosion-inhibiting admixtures fall into the specialty admixture category and are used to slow corrosion of reinforcing steel in concrete. Corrosion inhibitors can be used as a defensive strategy for concrete structures, such as marine facilities, highway bridges, and parking garages, that will be exposed to high concentrations of chloride
Admixtures used in concrete Properties of concrete are modified by small quantities of admixtures, depending on the site conditions and requirement. Many types of admixtures are available in the market, and they are grouped into various categories like:
Silica fume is another mineral types of admixtures used for concrete construction. The silica fume is manufactured during the production of silicon or Ferrosilicon by electric arc furnaces at a temperature of 2000 degree Celsius. Silica fume is a spherical particle with an average diameter of 150nm.

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?
Jul 09, 2018 1. Accelerating Admixtures: This admixture is added in concrete or mortar for increasing the rate of hydration of hydraulic cement and for shortening the setting time. Calcium chloride (CaCl2) is the most widely used accelerating admixture. Accele...
Most commonly, regular concrete is created by mixing Portland cement with both an aggregate and water-chemical mixtures. Often times, cement and concrete are incorrectly interchanged: concrete is the hard, rock-like substance that is so frequently seen in urbanized areas. Cement is an ingredient, the powder, used in the creation of concrete.
