Does Plasticizer Weaken Concrete?

Adding an excessive amount of plasticizer will result in excessive segregation of concrete and is not advisable. Depending on the particular chemical used, use of too much plasticizer may result in a retarding effect.

Does plasticizer make concrete stronger?

Superplasticizers (SP's), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. ... The strength of concrete increases when the water to cement ratio decreases.

What is the purpose of plasticizer in concrete?

Plasticizer is used to increase workability in concrete. Due to plasticizer, we can reduce the water-cement ratio up to a certain limit. Basically, water-cement ratio is used for workability and hydration of cement.
