Physical properties of concrete were studied, and compressive strength of concrete produced in steel-lead mould was found 10〜20% smaller than mixture strength obtained by JASS 5, 3, 5. This may come from the electrolysis of concrete. and is verified by the fact that chemical constituent of cement paste modified by electrolysis is found on moulds, that the color of concrete is different from that cured in natural conditions, that alkalinity is high on positive pole and low on negative pole as measured with PH meter, and that strength of concrete electrically cured is smaller than that steam cured. Thus admixture is added to concrete for remedying defects due to electrolysis by making electrolytic polymerization to occur in concrete. Thus electrolysed admixture will promptly react with constituents of concrete and become insolube before C_3A of cement is electrolysed, consequently alcalinity of electrically cured concrete becomes higher than concretes cured in natural condition, and the strength of electrically cured concrete becomes amount 10% higher than the mixture strength obtained by JASS. 5. 3. 5.
