Self Compacting Concrete offers many advantages over conventional concrete. It is mainly used when a great fluidity is required (For example sections with high percentage of reinforcement). Self Compacting Concrete has excellent applicability for elements with complicated shapes and congested reinforcement. An experimental study was made on cylinders and specimens with square sections confined ...

A series of analytical solutions are presented for viscous compacting flow past a rigid impermeable sphere. The sphere is surrounded by a two-phase medium consisting of a viscously deformable solid matrix skeleton through which a low viscosity liquid melt can percolate. The flow of the two-phase medium is described by McKenzie’s compaction equations which combine Darcy flow of the liquid melt w...

The incorporation of silica fume into the normal concrete is a routine one in the present days to produce the tailor made high strength and high performance concrete. The design parameters are increasing with the incorporation of silica fume in conventional concrete and the mix proportioning is becoming complex. The main objective of this paper has been made to investigate the different mechani...
