Use of Hydro demolition for Concrete removal in Unbonded Post-tensioned systems (ACI 364.8T-02(11))
Description Hydro demolition is one of many methods available for concrete removal on horizontal, vertical, and over-head surfaces. This technique uses very high-pressure water (20,000 to 40,000 psi [140 to 280 MPa]) to remove concrete. Hydrodemolition has some advantages over other methods, including speed. Based on available evidence,1,2 it does not cause significant microcracking or […]
