Properties of leakage corrosion of concrete and its durability

Abstract

The properties and mechanism of concrete under water leakage corrosion were studied in terms of the dissolution of calcium oxide and silicon oxide from concrete and the variation of pH value of permeate water. The experimental results show that the amount of calcium oxide and silicon oxide dissolved from per cubic meter of concrete gradually decrease with penetration time and ultimately stabilize at a certain value. The pH value of permeate water descend along with penetration time. The durability of concrete under leakage corrosion was analyzed by a formula fitted on the dissolved amount of calcium oxide.
