Scope of application: suitable for frost-resistant concrete, impermeable concrete, sulfate-resistant concrete, concrete with serious water secretion, poor concrete, light-aggregate concrete, ordinary concrete prepared with artificial aggregates, high-performance concrete and concrete with finishing requirements.
1、Introduce fine, uniform and persistent air bubbles in the concrete mix.
2、This product can adjust the concrete's compatibility and improve the poor fluidity of concrete caused by poor aggregate grading.
3、This product can reduce the slump of concrete through time loss.
4、The product has certain auxiliary water reducing effect and anti-mud effect.
5、It can improve the ability of concrete to resist freeze-thaw cycle, and it is more effective to be used with antifreeze agent in winter.
6、This product is suitable for various types of master batch.
It can be used in various types of concrete water reducing agent, the amount of 0.02-0.15%, according to the different materials and construction requirements flexible adjustment of the amount added.

The air-entraining agent is a new generation of high-performance air-entraining agent independently developed by our company. There are two specifications of liquid and powder, liquid is colorless or brown liquid, powder is white or yellow-brown powder.
This product can be introduced in the new concrete independent uniform tiny bubbles, significantly reduce free water, significantly improve the ease of concrete, improve the plasticity of concrete, reduce concrete segregation, water secretion, improve pumpability: because the introduction of the concrete in the dense tiny bubbles, can prevent the concrete due to freezing ice volume expansion and damage to the concrete structure, improve the concrete frost resistance, seepage resistance, carbonation resistance and other durability indexes. The product has good compatibility with other admixtures, and can be used as the air-entraining component of compound admixture to improve the product performance. This product mainly implements GB8076 ""Concrete Admixture"" standard, and all performance indexes meet or exceed the above standard requirements.
