Abstract:
Three special techniques (high speed slurry mixing, seeding, and revibration) and two admixtures (fly ash and lignosulfonic acid water-reducing agent were employed in a research program designed to produce high compressive strength concretes in the range of 6000 to I 1,000 psi (420 to 770 kg/cm2). The water-reducing agent, high speed slurry mixing, and revibration, appear to hold the most promise for increasing the compressive strength of concrete in this strength range. It should be noted that coarse aggregate was not used in this study.
