MasterCast 900 plasticizing admixture, based on a unique, patented chemistry, improves the production efficiency and aesthetic appeal of manufactured concrete products. MasterCast 900 admixture exceeds the functionality of traditional plasticizing chemistries. It additionally disperses cement, pozzolans, and integral pigments, further reduces
Chemical Admixtures - Cement
Accelerating admixtures are especially useful for modifying the properties of concrete in cold weather. Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.
Admixtures | Super Plasticizers - RussTech
RussTech carries a full line of super plasticizing concrete admixtures including ones that contain the new polycarboxylate technology. These high range water reducers have been specifically designed to increase strength while maintaining extended flowability at lower water to cementitious ratios in the concrete mix. SuperFlo 443. SuperFlo 2000RM.
- What are plasticizer admixtures?
- These admixtures are known as plasticizers. The combination of organic substances or combinations of organic and inorganic substances which cause reduction in water content for a given workability or give a higher workability at the same water content are known or termed as plasticizer admixtures. These are used for the following proposes: 1.
- How much does a plasticizer increase workability?
- At the same water/cement ratio, the increase in workability may range from 30 mm to 150 mm slump depending upon the initial slump of concrete, type of cement, content of cement and dose of the plasticizer. A good plasticizer produces fluidity in concrete or mortar in a different way than that of an air entraining agent.
- Why do plasticizers increase the strength of concrete?
- The dispersing ability of plasticizers (water reducing admixtures) results in a greater surface area of cement exposed to hydration. For this reason there is an increase in early strength of concrete than that of admixture free concrete of the same water/cement ratio.
- Why do we use plasticizer?
- The use of plasticizer is found to improve the desirable qualities of the plastic or green concrete. For making reinforced concrete or mass concrete of higher workability nowadays it has become a standard practice to use plasticizer or super plasticizer.
- Why do we use super plasticizer in concrete?
- Nowadays the use of super plasticizer has become a universal practice to reduce the water/cement ratio for the given workability. The reduction in water/cement ratio increases the strength and improves durability of the concrete. Sometimes plasticizers are used to reduce the cement content and heat of hydration in mass concrete.
- What is the use of plasticizers in concrete?
- The reduction in water/cement ratio increases the strength and improves durability of the concrete. Sometimes plasticizers are used to reduce the cement content and heat of hydration in mass concrete. Generally following materials are used as plasticizers: 1.
