| Abstract: | Tests of restrained initial shrinkage properties with plain and polyacrylonitrile fiber reinforced concrete and mortar are introduced in this paper. The results of tests show that the polyacrylonitrile fiber reinforced concrete and mortar have good crack inhibitors of early period. The curing condition has significantly effects on the early crack inhibitors |
