Self-Compacting High Performance Concrete: Structural ...

23/03/2018  A self-compacting high performance concrete has been developed that is not affected by workmanship during placing and requires no consolidation afterwards. Self-compacting concrete can save labor, eliminate consolidation noise and lead to innovative construction systems. It has been used in Japan for bridge girders, towers and piers, LNG tanks, culverts and building structures. Precast ...

SELF-COMPACTING HIGH-PERFORMANCE CONCRETE

Self-compacting high-performance concrete is a high performance concrete that can be compacted into every corner of a formwork, purely by means of its own weight and without the need for vibrating compaction (Fig. 1). This concrete is defined as follows at the three stages of concrete: (1) Fresh: self-compactable; (2) Early age: avoidance of initial defects; (3) After hardening: protection ...

High Performance Concrete Self-Compacting Concrete ...

16/09/2013  High strength concrete (HSC) might be regarded as concrete with a strength in excess of 60MPa and such concrete can be produced as relatively normal concrete with a higher cement content and a normal water-reducing admixture. However ultra high performance concrete (UHPC) will more usually contain cement replacement materials and a high-range water-reducer (HRWR) or

High Performance Concrete - Mick George - Self Compacting

Our new specially formulated high-performance, self-compacting concrete can be used to create stronger and more durable floor slab with less shrinkage and increased bay sizes, to minimise joints compared to those constructed with conventional concrete.. Higher compressive and flexural strengths are achieved enabling a reduction in slab thickness; providing an improved environment profile.

03/05/2021  Introduction. Construction of large-span and super high-rise concrete structures has become a current trend [], posing an increasingly stringent requirement for the compressive strength of concrete.For this reason, self-compacting concrete (SCC) with high strength, self-compacting ability, and excellent load-bearing performance has been gradually used in civil engineering.
