A new generation liquid admixture with patented biopolymer, formulated to enhance paste rheology and control cementitious material hydration, V-Mar VSC500 is billed as the first admixture specifically for pervious concrete. Among benefits the agent imparts, Grace notes: consistent quality and limited load-to-load mix variability; improved flowability for rapid discharge from mixer trucks; broader moisture tolerance, reduced evaporation, and uniform compaction. V-Mar VSC500 is dosed at 9 to 15 fl oz/100 lbs of cementitious materials, and meets provisional requirements for an ASTM C494 Type D admixture. Û www.graceconstruction.com
