Title : Grace 303 :S.P.M

‌Description : Grace 303 :S.P.M -S.P.M is a liquid for plasticcing the concrete and minimizing concrete water -S.P.M can reduce the water degree in the concrete about 30% -S.P.M contains no choloride .Not only dosn,t it cause any covrosion , but it provide a desirable condilions which don,t allow concrete decay and covrosion . _S.P.M mechanism is 100% similar to that of superplasticzers . so it is useful for microcilica concrete and concrete with silica stone -S.P.M increases concrete pressuve resistance all the time Dosage : Depending wpon water , cement quality ,type of cementand its mixture ,s.p.m dosage ranges from 30/00 and 1/2% of cement weight .The 2/8% dose is also permissible , but it canses 2-hour retardation Admixtuc: The best output of s.p.m is when it is added to concrete in a diluted form at the final stoge of mixture .It is ,also , added to the concrete water
