SIRIUS PARTICLE ACCELERATOR
Sirius is the largest and most complex scientific infrastructure ever built in Brazil and one of the most advanced synchrotron light sources in the world.
There were many challenges for the construction of the facilities that house Sirius, from the stability of the floor against deformations and the isolation of internal and external vibrations to the thermal stability of the environments and components. All construction aspects, from the foundation to the roof, had to consider unprecedented mechanical and thermal stability requirements.
For this remarkable engineering feat, 30,000 m³ of Special Concrete was used in the floors and tunnels of the particle accelerator, incorporating SRA, AC DRY, and Hardener.
TIETE SHOPPING
Tietê Plaza is a modern and bold shopping center, offering a diverse mix of 219 stores and providing complete infrastructure for shopping and leisure, spread over an area of 36,000 m².
The floor curing process used the AC 309R Chemical Curing system, which ensures optimal hydration of the concrete by delaying the excessive loss of water from the fresh concrete until it hardens. This results in better cement hydration, increased surface strength of the concrete, and prevents cracks caused by plastic shrinkage.
HIGH-TRAFFIC LOGISTIC CENTER
A logistics center in Campinas, built for production, logistics, and storage, needed a floor to handle 2 tons-force/m² linear load, 6 tons-force/m² distributed load, 4.5 tons-force per pallet rack footing, and 7 tons-force per forklift axle. A wear-resistant, hardened floor was vital. A surface hardener increased concrete durability, reduced wear and dust, and protected against impacts and abrasion. AC309, an acrylic curing compound, prevented cracks and improved uniformity by slowing water evaporation. The result: a durable, stable floor for heavy equipment, concreted at 5,000 m² daily, ideal for high-traffic industrial use with minimal maintenance
