Superplasticizer

Superplasticizer

+

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. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent.

How to Calculate Water Cement Ratio

How to Calculate Water Cement Ratio

+

HOW TO CALCULATE WATER CEMENT RATIO. The water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement the mix is a .50 water to cement ratio. If the mix lists the water in gallons ...

 · We've talked extensively before about how much the characteristics of concrete are influenced by the ratio of water used in the mixture. Reducing the amount of water creates a higher density, and higher quality, cement paste. Water content can't simply be reduced without taking any other measures. Higher water content is needed so that the concrete can remain workable. If you simply .
