UC BERKELEY ISN'T ALL STUDENT UNREST

Research at the University of California at Berkeley by Professor Kumar Mehta has revealed that the addition of very small quantities of latex-type admixtures to concrete during mixing can prevent or considerably reduce the stiffening process for 30 to 60 minutes - the time usually required for transportation, placing, and finishing concrete. This "slump loss" has previously been corrected by adding water at the site but this process also reduced the strength and other desirable qualities of the concrete after set up and curing. The patented process requires only 0.1 to 0.25 percent latex by weight of cement offering very economical benefits.
