Different types of admixtures used in concrete
To improve the performance of concrete, concrete is used in many types of mixing concrete, and concrete mixing is defined as the addition of water to concrete and materials in addition to cement. So the following are the admixtures which are used in concrete to enhance its bondage:
Water reduction mixer: a. Solid-affected compounds are used to increase solid strength and work efficiency and reduce costs. They are those which contain some organic compounds or compounds of organic and inorganic compounds to reduce the need for mixed water for a particular decomposition.
Retiring adhesives are used to slow down the fixing rate of concrete. By slowing down the initial stabilization time, the concrete mixture can survive in a new mixing state before it reaches solid form.
Air-entraining concrete admixture:
Air entraining agent is an admixture that causes the development of a system of microscopic air bubbles in the cement paste during mixing, generally to increase its resistance to freezing and thawing and improve maneuverability
Moisture Absorbing Additives:
Waterproofing is a process in which a mixture (traditionally tar or unmodified asphalt) is used as a coating on the exterior side of a structure and has one main purpose: to stop transfer or leaching. ‘Evacuation of soil moisture through concrete.
Gas Forming Aids:
Gas Forming Aids help maintain the initial volume of concrete, neutralizing slump and bleeding, generating or releasing bubbles in the mix.
Adjutants that inhibit expansion of alkaline aggregates:
Adjutants that are added to cement to reduce the expansion of alkaline aggregates include chemical adjutants and other adjutants such as silica fume, fly ash, slag, and other materials. silica base. The upper curve shows the effect of dilution with a weakly alkaline cement.
These additives are used in cement-based and non-cementitious grouts to improve their flow and other set characteristics. The ability to change all fluid properties and settings improves the durability, strength, and penetration strength of plaster.
To improve adhesion, bonding aids are added to the cement or grout that is applied to the concrete surface just prior to placing the fresh concrete. This type of additive is used for paving, screed on the roof, repair work, etc.
Fungicidal, Germicidal, Insecticidal Adjutants:
To prevent the growth of bacteria, germs, fungi in hardened concrete structures, it is recommended that the mixture have fungicidal, germicidal, and insecticidal properties.
If you want these additives you can easily get them from Malaysian chemical suppliers or chemical manufacturers.
