Project description & CHRYSO expertise

This jobsite represents 55 000 m3 of concrete, 35 000 m3 for flues structures, 2 tunels for jet engine evacuation, 180 meters long. It is one of the main structure of this new launch pad. The other two are technical building and mobile portals as a 6000 tons‘ « steel cathedral » measuring 100 meters hight.

With a strong experience gained on the construction sites of Ariane 4 and 5, CHRYSO team provided a recognized expertise for this such major Project.

Several laboratory and in situ tests with CHRYSO/SAM local team support, have allowed to develop a mix design for concrete including a superplasticizer, CHRYSO Fluid Optima 224 and synthetical fibrilled Micro-fibers, Fibrin 1950D.

PRODUCTS USED

  • Superplasticizer: CHRYSO®Fluid Optima 224
  • Synthetic microfibre: FIBRIN 1950 D 
  • Special admixture: CHRYSO® Remblai Dose

Project technical challenges

For this Jobsite and more particularly for flues constructions, launch pad building foundation, water tower and its ditch launch pad, CHRYSO Technical teams provided an answer to three main challenges:

  • Concrete stability (bleeding risk with local materials)
  • 90 minutes Open Time
  • High early strengths & 28-day compressive strength
