未标题-1.jpg

DESCRIPTION：GK-20A consists of anti-punching and wear-resisting components, reducing components, regulating setting time components and strengthening components. Through special production technology, it can improve cement to hydrate compact, hard and with high strength.

USES：GK-20A is widely used in highway, bridge deck, airport, hydroelectric dam and so on, especially suitable for the parts of concrete in water conservancy and hydropower projects that need abrasion resistance and impact resistance.

CHARACTERISTICS：

GK-20A offers the following advantages:

* Water reduction capacity above 15% can be achieved;

* No need to add other water reducers;

* Improves workability of fresh concrete, avoiding segregation or bleeding;

* Has significant high density wear resistance, high temperature stability and low temperature anti-crack resistibility and improves toughness of concrete.
