The over all project budgeted Rs.1078 Cr. 2019 THE BENEFITS

The overall concrete volume requirement of 800,000 Cu.M was needed for this project, out of which PQC segments having a volume approx. 500000 Cu.M and Structural Concrete (Pile, Pile cab & Bridge Griders) segment having a volume approx. 300000 Cu.M. The PQC had more challenges due to the Strength (Flextural) and Workability Larsen & Toubro considerations (2hrs – 50mm). The Elevated construction had structures like diaphragm wall, pre-cast segments, slabs and the grade of concrete ranges from M-35 (Pile & Pile Cab) to M-45 (Bridge Girder) respectively. Chryso® HP 6180 is one of Chryso’s robust admixtures achieving remarkable strength results with a Compression Testing as 68Mpa @ 28 days. Further, the combination of Copper Slag with low W-C ratio made the customer further satisfied. To supplement this, the precast concrete structure has proved Chryso’s product

performance by giving target strength of 56 Mpa at 7 Days with good retention and the Chryso’s Chryso® HS © CHRYSO 2021/09/26 3287 Product performance by giving homogeneous mix with 50mm @ 2hrs in M40 PQC grade concrete mix. And achieving remarkable Strength results with a Flexural Testing as 7Mpa @ 28 days
