Simply put, SCC saves labor, increases quality and shortens construction time.Although its use is not widespread in North America, it is already common in Europe and other parts of the world.For example, a large percentage of precast concrete is manufactured today using SCC technology.
The J-Ring Test Set is used to characterize the ability of self-consolidating concrete (SCC) to pass through reinforcing steel.
The test is useful for both mixture qualification and quality control testing.
In spite of this, there has been a significant lag between the development of the technology and full scale acceptance and use.
While there is always a period of adjustment prior to the adoption of any new innovation, the cast-in-place concrete construction industry as a whole has traditionally been slower than most to embrace new methodologies.
Nowadays, its use is progressively changing the method of concrete placement on building sites. Influence of composition on free plastic shrinkage 86 2.7.
However, the successful use of SCC requires a good understanding of the behavior of this material, which is vastly different from traditional concrete.
(b)The Purchaser is responsible to provide Seller with safe and reasonable access for Seller’s delivery truck to deliver the Concrete.
Seller reserves the right to stop deliveries until Purchaser provides such access.(c)Concrete will have slumps of 80mm /- 20mm unless otherwise specified in writing.(d)Quotations are based on the volume of Concrete in a plastic and unhardened state at the time of discharge from the Sellers delivery truck.
For loads smaller than 7.0 m3 a small load charge may apply.
