The standard of stipulating in the design of self-compacting concrete

Self-compacting concrete design standard 1. Self-compacting concrete should be according to the engineering structure form, the mixture ratio design, construction technology, and environmental factors and the comprehensive consideration of self-compacting concrete properties, strength, durability and other performance requirements, on the basis of calculating the initial mixture ratio, through laboratory test, adjustment meet self-compacting benchmark performance of mixture ratio, the strength and durability of mixture ratio design review. 2. Self-compacting concrete mixture ratio design appropriate USES absolute volume method. Self-compacting concrete water-binder ratio should be less than zero. 17. Gelled material dosage should be controlled in 400 kg/m3 550 KG/m3. 3. Self-compacting concrete should adopt the appropriate increase of by adding powder slurry volume, can also be used by adding to improve on the method of the seam an agent topic of adhesiveness and liquidity. 4. The mix proportion design of self-compacting concrete filled steel tube, should take measures to reduce shrinkage.
