Experimental Investigation on PCE and SNF Type Admixture on
Optimum dosage of super plasticizer improves the workability of concrete without adding excess water. At a dosage of 0.5% of SNF super plasticizer (Sikament 2002 NS) and 25% water reduction, maximum strength achieved. At 0.6% of PCE super plasticizer (C Flow 175 M) and 25% water reduction all the strength parameters reached peak value.
Effects of Super Plasticizing and Retarding Admixtures on
The average percentages of increasing in compressive strength were 9.7% at 7 days, 10.8% at 28 days, 9.1% at 56 days and 9.3% at 90 days than control mixture.
Use of Water Reducers, Retarders, and Superplasticizer
There are four types of superplasticizers: sulfonated melamine, sulfonated naphthalene, modified lignosulfonates and a combination of high dosages of water reducing and accelerating admixtures. Commonly used are melamine based and naphthalene based superplasticizers.
- What is a superplasticizer admixture?
- Superplasticizers belong to a class of water reducers chemically different from the normal water reducers and capable of reducing water contents by about 30%. The admixtures belonging to this class are variously known as superplasticizers,” “superfluidizers,” “superfluidifiers,” “super water reducers,” or “high range water reducers.”
- Does superplasticizer admixture increase concrete strength?
- No extra water is needed. The fluidity is increased so as to increase the concrete strength. Superplasticizer admixture helps to build a strong and durable structure. During concrete construction, water is added to make it easier to work with. But too much water can weaken the concrete and reducing its strength.
- What is water reducing admixture & superplasticizer?
- As one of the concrete admixtures, water reducing admixtures and superplasticizers are usually used to reduce the mixing water volume and improve the performance of the harden concrete while maintaining better workability of the fresh 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 the difference between a plasticizer and a superplasticizer?
- 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. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete.
- 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.
