Condition Survey of Lock Number 2, Monongahela River
A condition survey was performed at Locks and Dam No. 2 on the Monongahela River in Pennsylvania to determine the extent of possible concrete damage, processes causing distress of the concrete, selected physical and mechanical properties of the concrete and foundation materials, and the ability of the concrete to perform satisfactorily under anticipated conditions of future service. The field investigation included a visual inspection of the structure to determine the general condition of the concrete, and drilling operations to recover concrete and foundation core. Results of the field investigation and laboratory tests indicated that the concrete is generally in good condition, with dissolution of carbonate aggregate particles giving the appearance of exposed aggregate to the concrete. Some pop outs, scaling, and spalling are also present. The near surface concrete contains some cracking not associated with any apparent chemical reaction. The cracks do not appear to be active. The concrete in this structure should remain serviceable for a period of 50 years from the data of this investigation. (fr)
