Abstract
A non-dispersible concrete for underwater construction is disclosed, which composition includes: coarse aggregates in the range of 600~1200 kg/m3; fine aggregates 500~1100 kg/m3, its fineness modulus (F.M.) ranges between 2.2~3.2; powder 300~700 kg/m3; mixing water 140~300 kg/m3; and, the solid content of cohesion-enhancing admixture (for example, polyacrylamide, PAA) 0.1~5.0 wt% of the powder. In addition, a self-compacting concrete for under water construction is also developed and has excellent property of self-compacting (its test value is 400~750 mm in slump flow spread test) and an appropriate normal strength (between 140~630 kgf/cm2), so as to widely apply to common underwater construction and earthwork, which composition includes: coarse aggregates in the range of 600~1100 kg/m3; fine aggregates 500~1100 kg/m3; powder 300~700 kg/m3; mixing water 140~300 kg/m3; the solid content of cohesion-enhancing admixture (for example, polyacrylamide, PAA) 0.1~5.0 wt% of the powder; and, the solid content of water reducing agent 0.1~3.0 wt% of the powder. The invention also discloses design processes and mixing methods for the non-dispersible concrete and the self-compacting concrete for underwater construction.
