CICO provides solution to IRCON for their Delhi-Mathura Concrete Highway Project.

PROJECT REQUIREMENT
The ADB aided 92 km. Delhi-Mathura Highway Project in Haryana and Uttar Pradesh involved construction of zero maintenance high strength concrete pavement designed with latest technology requiring adequate modern infrastructure. The project was awarded to M/s. Indian Railway Construction Co. Ltd. (IRCON). They have wide experience with reputation to execute prestigious projects around the world.

During the first phase of the construction work. several difficulties were experienced by the contractors especially that of the retention of workability in summer. The specifications for this concrete pavement called for 28 days compressive strength of 530 kg/cm2 concrete with initial slump of 40 to 60 mm with a retention after 45 minutes to be around25 mm +/- 10 mm. The average time estimated between mixing and placement of the concrete was around 30 minutes. This is the time when CICO Group got involved with IRCON and provided the correct superplasticiser, required for the job. CICO PLAST SUPER - HS is high range water reducing concrete admixture based on blend of high molecular weight polymers. The significant advantage of this admixture over conventional European style additives lies in its compatibility in high ambient temperatures at places like India.

Several hundred trials were conducted both at the site as well as in the field laboratory with various brands of superplasticisers. But IRCON selected CICO PLAST SUPER - HS which fulfilled all the critical paarmeters stipulated for the site conditions with the optimum cement consumption.
