PRE-CAST
Precast Concrete is widely used in low- and mid-rise apartment buildings, hotels, motels, and nursing homes. The concrete provides superior fire resistance and sound control for the individual units and reduces fire insurance rates. It is also a popular material for constructing office buildings.
Sika Precast Technologies
In this industry, a concrete element producer sells a finished technical product, though its quality and surface appearance are the producer’s calling card.
The pre-cast concrete element producer bears responsibility for technical performance, compliance to standards and durability of products. The production process for this elements is increasingly industrialised, and efficiency is essential. Because they execute the entire production process, this element manufacturers encounter a myriad of requirements.
In addition to being efficient the production process should be sustainable and environmentally friendly, holding the CO2 footprint of the product to a minimum. Besides ecological concerns, health and safety of workers also continues to grow in importance. Structural design and construction with precast concrete elements requires versatile chemical products, from wet precast production to erection on site. Sika meets the diverse complexity of the entire precast concrete element production and construction process with solutions for all requirements.
With advanced concrete technology and suitable admixture application, adequate workability, rapid installation and subsequent fast strength development of the concrete can be ensured whereas fast strength development is critical for swift production.
Application of innovative concrete mix designs such as Self-Compacting Concrete (SCC) offer further advantages. Besides rapid installation, vibration work can be eliminated, substantially improving the working environment in a precast concrete factory.
Advantages of Precast Concrete Construction :
- Very rapid speed of erection.
- Good quality control.
- Entire building can be precast-walls, floors, beams, etc.
- Rapid construction on site.
- High quality because of the controlled conditions in the factory.
- Prestressing is easily done which can reduce the size and number of the structural members.
