②Improve the durability of concrete. Because a large number of fine air bubbles in the concrete clogging and blocking the capillary tunnel, and because of bleeding less water, bleeding caused by water SLIT also reduced. Therefore, the impermeability of concrete can be greatly improved. Improve corrosion resistance and weathering resistance.In addition to our broad portfolio of existing products, BASF can develop tailor-made products for customer-specific requirements, including in the range of methylpolyethylene glycols or acrylates. As well as our building blocks for polycarboxylate ethers we offer other additives for concrete admixtures for use as:
