Recommended uses of MasterGlenium 3030 concrete superplasticizer: Concrete where high flowability, high-early and ultimate strengths and increased durability are needed; Self-consolidating concrete
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.
High Range Water Reducer - Sika
Sika ViscoCrete-2100. HIGH RANGE WATER REDUCING ADMIXTURE. Sika ViscoCrete-2100 can be dosed in small amounts to obtain water reduction from 10-15%, and will achieve water reduction up to 45% at high dosage rates. Sika ViscoCrete-2100 is suitable for all levels of water reduction.
Polycarboxylate Superplasticizers - Concrete Construction
Subsequent to the introduction of so-called general purpose PCE superplasticizers, new PCE products have been developed especially designed to provide high early strength and different levels of slump retention, as well as provide different capabilities to manage air contents in concrete.
- What is a superplasticizer admixture?
- Superplasticizers are water-reducing admixtures used in concrete production to reduce the need for more than 30% of water. They operate at a certain percentage level. One of their main purposes is to prevent concrete from setting too quickly.
- 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.
- 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.
- 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 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.
