Features of ART-JA

Water reduction rate exceeds 25%, granting the concrete mix excellent fluidity.

Significantly reduces the setting time of concrete, capable of shortening the setting time of concrete by 2 to 8 hours.

Intelligent viscosity adjustment function, ensuring good flowability of the concrete between the gaps of steel reinforcements and complex formwork structures, guaranteeing the uniformity and integrity of the concrete.

Low air-entraining, with air content in the concrete less than 2%, enhancing the compactness and durability of the concrete.
