Self consolidating concrete mix
Reinforced concrete (RC) structures constitute about 70 % of today’s infrastructures and for economical reasons structural engineers are under tremendous pressure to design smaller and shallower RC members.
Such practice usually leads to heavily reinforced members especially in beam-column connections and in structures located in high seismic regions.
In addition, global warming is a major problem for todays and future development and most industries are shifting toward sustainable and green practices.
Sustainable technologies such as supplementary cementitious materials (SCMs) and recycled materials are some of the attractive options to achieve green concrete.
Self-consolidating concrete or self-compacting concrete (commonly abbreviated to SCC) is a concrete mix which has a low yield stress, high deformability, good segregation resistance (prevents separation of particles in the mix), and moderate viscosity (necessary to ensure uniform suspension of solid particles during transportation, placement (without external compaction), and thereafter until the concrete sets).
The relatively high cost of material used in such concrete continues to hinder its widespread use in various segments of the construction industry, including commercial construction, however the productivity economics take over in achieving favorable performance benefits and works out to be economical in pre-cast industry.
Once the fresh concrete has been placed into the container, it can be conveyed through the pump–pipe– nozzle system to print out self-compacting concrete filaments, which can build layer-by-layer structural components.
Self-Consolidating Concrete Mix (BOM #110768) is a dry, preblended, one-component, self-consolidating, cementious, polymer-modified concrete mix containing coarse aggregate, silica fume, and an integral migrating corrosion inhibitor.
Designed for application thickness minimum of 1" and maximum thickness of 8".
