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
