Effects of Super Plasticizers on Concrete | Concrete Technology
Super plasticizers due to the reduction in water/cement ratio, reduce the penetration of chlorides and sulphates into the concrete and thus improve the resistance to the sea water or deicing effect. The resistance to sulphate attack also has increased due to the same reason.
The percentage of superplasticizer and water cement ratio
Superplasticizer is possible to use also in powder form as BASF Melflux line or similar polycarboxilates polymers. But they are very expensive (more than 12 /kg in Italy). Lightweight concrete...
- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- What is a superplasticizer in concrete?
- Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes. They achieve a reduction in water content without loss of workability.
- Can super plasticizers reduce water content in concrete mix?
- The use of super plasticizers can permit the reduction of water in the concrete mix upto 30% without producing any ill effect on the workability of the concrete i.e. without reduction in the workability of concrete, where as normal plasticizers with doses upto 0.1 to 0.4% by weight of cement can reduce water content from 5 to 15%.
- What is a super plasticizer?
- Classification of Super Plasticizers 3. Uses. Super plasticizers are also called high range water reducers. They are of recent origin and relatively are more effective type water reducing admixtures. They were developed in Japan and Germany during 1960 and 1970 respectively. Chemically they are different from normal plasticizers.
- Does superplasticizer increase compressive strength?
- Addition of super plasticizer allows for better flowing concrete, which allows for a system with lower number of voids. As a result, the maximum attainable compressive strength increases with increase in superplasticizer dosage. As super plasticizer dosages increase, the water requirement to attain maximum compressive strength reduces.
- Why do superplasticizers reduce density vs Water cement?
- At higher dosages of superplasticizer, the repulsive charges induced by the super plasticizers restricts the quantity of materials that can be packed into a given volume, resulting in reduction of density. The better flowing mix helps in reducing the water required to attain the maximum density. Fig. 2. Density vs water cement ratio.
