摘要：
Within the framework of studying properties that inhibit corrosion of concrete that contains admixtures and additives, concretes with various amounts of fly ash were tested and evaluated. Cylindrical specimens with a centrally located reinforcing bar were partially immersed in a 5 percent sodium chloride solution after various curing periods and curing procedures. An impressed-current test was used to accelerate the corrosion process. Time to cracking and current flow were measured, and total energy requirements to induce failure calculated. Other variables studied included sorption, resistivity, strength, consistency, and time to cracking failure of the specimens.
