| Description: | Technical Report Abstract: Mortar bars were made from 23 Type I, 9 Type II, 2 Type V, 15 Type IP, 5 Type IS, and blends of Type I with slag and with various pozzolans including one silica fume. The bars were stored in a 5-percent sodium sulfate solution and monitored for changes in length and in resonant frequency. The length changes of the bars indicated that silica fume and a natural pozzolan showed impressive improvement of the blends over the use of a nonsulfate-resistant cement by itself, while blends made using slag, and other pozzolans in the amounts studied, in some cases showed only slightly improved resistance and in other cases no improvements. |
