    Air entrainment: Essentially all polycarboxylate-based admixtures are formulated with a defoamer to control unwanted air entrainment inherent with the PCE polymer.For both air-entrained and non-air entrained concrete applications, air contents can usually be effectively managed with selection of the PCE-based superplasticizer product most compatible with job materials.

    Concrete Admixtures: Accelerating . Accelerating concrete admixtures are used to increase the rate of concrete strength development or to reduce concrete setting time. Calcium chloride could be named as the most common accelerator component; however, it could promote corrosion activity of steel reinforcement. Nonetheless, concrete best

    Vice versa, admixtures for cold countries, winter time or precast concrete often contain accelerators to speed up early hydration. Examples of accelerators are calcium chloride, calcium nitrate, calcium nitrite, calcium formate, thiocyanates, triethanolamine, hydroxy amino compounds, and blends thereof.

  • 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 ca. 15% less water content. Superplasticizers allow reduction in water content by 30% or more.

    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.
