Polycarboxylic acid water-reducing agent is the most common additive in concrete, which can improve the workability, wrapping force and corrosion resistance of concrete.However, the simple use of polycarboxylate water reducer can not meet some specific needs, we need to add some additives in the configuration.Let's take a look at what needs to be done to improve the crack resistance of polycarboxylate water reducer.
Polyols, water-repellent components, reducing components and alcohol-modified components can be added to the polycarboxylate water reducer to reduce the water permeability of concrete under hydrostatic pressure, improve the impermeability of concrete and improve its durability.In the process of deploying polycarboxylic acid water-reducing agent with high crack resistance, the standards such as gb8076-1997 concrete admixtures, gb50119-2003 technical specifications for the application of concrete admixtures and JC 474-1999 mortar and concrete water-proofing agent should be implemented.
Poly carboxylic acid high efficiency water reducing agent manufacturer said, if you want to configure the good effect of poly (carboxylic acid water reducing agent, only in accordance with the manual configuration is not enough, must according to the use of specific requirements, the organization related experimental work, find the raw materials used sand, stone aggregate, water and the collocation of admixtures such as the most accurate mixture ratio, don't be an armchair strategist.
