the POWeRCRete PLUS SOLUtiOn
We innOvate betteR SOLUtiOnS fOR OUR CUStOmeRS
Powercrete Plus can create concrete with a wide range of strengths. It may be further blended on site with additional fly ash or slag, to meet different concrete design requirements. The product has the benefit of:• Improvedworkability:foreasierplacing,
better response to compaction, more efficientfillingofformworkandfinishingof concrete
• Highearlystrengthforbetterproductivity
• Reducedwaterrequirement:resultsinlesscrackingandmorestrength
• Bettercohesion:lesspronetosegregation
• Concretewithhigherlong-termstrengthand durability
• Betteroff-shutterfinishestomeetaesthetic requirements
