Compared to portland cement, rapid-hardening hydraulic cement reaches typical compressive strengths in a few hours that an equivalent portland cement mix would require one month to achieve.Rapid-hardening hydraulic cement has been used for both concrete repair and new construction, wherever superior durability and rapid strength gain are required.
We are a professional and innovative company with more than 60 years of experience in the field of crushing and mineral processing. Our new products always carry the latest technology to serve our customers.
