Abstract: The early crack of concrete is ubiquitous phenomenon in the engineering. Cracks seriously affect the durability of concrete, which is a hot research topic. The performance comparison tests of unfold capability of crack in the course of concreting are carried out between several flexible fiber dust plasma samples, in order to study the crack-resistance effect of different flexible fibers have on dust plasma samples at the same condition, which offers certain references to the design, construction and reinforcement of the bridge.

Key words: flexible fiber , dust plasma , concreting course , the unfold capability of crack , comparison ;
