concrete additives defoamer

Defoamers Construction Chemicals from Evonik

Defoamers are preferably used for the prevention and removal of large air inclusions at the concrete’s surface and for rapid foam collapse in aqueous formulations. If, on the other hand, it is necessary to remove finely distributed air from a system, deaerators are the preferred alternative. However, practice has shown that a clear differentiation between defoamers and deaerators is usually

Defoamers Bozzetto Group

Defoamers are suitable for removing the excess air englobed in concrete because of the recipe or the additives present in the mixture. Very low dose anti- foam products can reduce the number of bubbles and homogenise them so as not to affect the mechanical characteristics of the concrete and to ensure an optimal density for the end product.

INNOSPEC » Special Defoamer INNOSPEC

Defoamers are crucial components in the formulation of polycarboxylate ether (PCE) superplasticizers. One side-effect of using a PCE superplasticizer is that they pull an excess of air into the concrete slurry. Conventional defoamers, such as non-ionic surfactants with low HLB values, silicon derivatives, dibutyl phosphates and alkyl phtalates are generally added to reduce the amount of air in

Construction Chemicals for Concrete

Our AirVoid ® defoamers reduce concrete air content resulting in higher flexural, tensile and compressive strengths and improved abrasion resistance. The selection of the correct defoamer chemistry ensures that neither cement hydration nor the concrete’s early strength are adversely affected. Our new liquid defoamer additives portfolio offers an extensive range of surfactant chemistries and

US20040224869A1 Defoamer for concrete admixtures

The present invention is directed to a defoaming agent for use with polycarboxylate based admixtures for concrete. The defoaming agent is comprised of tributyl phosphate, an alkylaryl sulfonic acid metallic salt and a modified alkylpolyalcoxy ester. Tributyl phosphate is a phosphate ester based defoamer and the modified alkylpolyalcoxy ester is an air detraining agent.

Defoamers Halliburton

Defoamers (anti-foam additives) can control or prevent frothing, foaming and air entrainment in cement slurries that may occur during the mixing process. Excessive foaming can cause an underestimation of slurry density downhole. This is due to the entrapped air being compressed in downhole pressure conditions and increasing the density of the slurry over the lb/gal weight measurement gathered
