DESCRIPTION:GK-I Synergist is a new admixture comprised of mainly organic compounds. It can improve the performance of concrete when the cement content is reduced by 10% ~ 15%. The research demonstrated, that more than 20% cement in concrete cannot be fully hydrated due to the flocculating of cement particles, and it only ACTS as filler, especially in the case of low water-cement ratio, which causes a great waste. Synergist can further open the cement flocculation structure, increase the hydration of non-reacted minerals in cement, which not only increases the quantity of cement hydration products and improves the strength and overall comprehensive performance of concrete, but also saves cost. Meanwhile, it offers simple preparation technology and easy industrial production.
USES:GK-I is widely used in pre-mixed concrete, cast-in-place concrete, reinforced concrete, pre-stressed reinforced concrete for civil and commercial mixing station, concrete mixing station, cement plant, pipe pile enterprises, component enterprises, railway and hydropower engineering, as well as in concrete of different strength performance.
CHARACTERISTICS: GK-I offers the following advantages:
* Increases compressive strength by 28 days for 3—8MPa.
* Improves workability of fresh concrete, avoiding bleeding and creates ease of pumping;
* Reduces cement amount by 5%—20%;
* Improves strength and durability of concrete, as well as density, anti-permeability, anti-crack, freeze-thaw resistance and carbonation resistance ability, especially in high performance concrete;
* Non-toxic, no radioactivity, chloride free, no pollution, zero emission production, green environmental protection building materials.
