A Novel Technique for Crack Resistance of Bulk Mass Concrete Pier

Abstract:

The bulk mass concrete pier is esay to crack because of higher temperature contrast between inner and outer of concrete. Experimentation use admixtures to replace some of cement so as to low the hydration heat. Fly ash can decrease more hydration heat than granulated blast furnace slag. If 40 percent of cement in weight is replaced by same amount of blend admixture of fly ash and granulated blast furnace slag, not only the compression strength can meet the requirement of engineering design, but also the hydration heat reduce a lot. Meanwhile, this paper develops a novel lining fabric especially for concrete steel formwork to advance water-retaining property and warm-keeping efficiency, and to distract shrinkage stress by ways of veins of fabric. Because of developed lining fabric and optimized mixture in this paper, the cracking problem of bulk mass concrete pier is avoided.
