Swiss India Walk Behind Power Trowel

Remarkable increase in forest resistance. Increase in the wear resistance by 100 - 150 %. Porosity is reduced by 20% (i.e. Dense concrete). Surface permeability is reduced to 'O' (Under Laboratory Condition). Shrinkage of Vacuum treated concrete will be reduced by about 50%. Increase in the compressive strength by 40-70% (higher increase is at the top surface). Strength gain in Vacuum concrete is earlier than normal way thus earlier utilization is possible
