Sika Wet Precast Technology
Precast concrete production must be efficient, sustainable, and safe. From wet production to on-site erection, Sika offers versatile chemical solutions to meet every technical, ecological, and safety requirement across the entire precast process.
Sika's Concrete Admixture Products for Wet Precast
Set & Strength Accelerator Admixtures
Sika’s set and strength accelerators are designed to speed up concrete setting and early strength development, ensuring faster construction progress without compromising quality. Ideal for precast production, cold weather concreting, and applications requiring rapid formwork removal or early load-bearing capacity. These admixtures enhance performance, durability, and efficiency across a wide range of construction projects — from high-rise buildings and bridges to industrial floors and infrastructure works.
Advantages of High Strength Concrete
For ready mixed concrete, the advantages of early and high strength concrete are:
- Faster construction time
- Development of most cost-efficient mix designsLower concrete consumption (when thinner elements can be
designed) - Improved site capacity by increasing formwork rotationImproved service life of structure
For precast concrete, the advantages of a fast and defined strength development are:
- Rapid rotation of moulds and finishing of concrete surfaces
- Early pre-stressing at low temperaturesReduced energy consumption for heat or steam curing
- Development of most cost-efficient mix designs
- Reduced cycle times will allow the reduction of the number of moulds required
