近年来,随着建筑业的大发展,桩基工程也日趋繁多。通常在打桩中,时有桩头破碎报废而重打,既影响了工程进度,工程质量又不能保证。因此,对砼预制桩补强成为当务之急。 钢纤维砼就是将短细的分散性纤维均匀地撒在砼基体中,形成一种新型的复合材料,以达到改善砼原有易脆裂的性能的目的。因此,钢纤维砼最优越的特性便是抗冲击、抗弯、抗疲劳及韧性。
In recent years, with the development of the construction industry, pile foundation projects have become more and more numerous. Usually in pile driving, pile heads are scrapped and scrapped, which affects the progress of the project and the quality of the project cannot be guaranteed. Therefore, it is imperative to reinforce the precast piles. The steel fiber ray is to spread the short and fine dispersion fiber evenly in the cerium matrix to form a new type of composite material, so as to achieve the purpose of improving the brittleness of the crucible. Therefore, the most superior characteristics of steel fiber enamel are impact resistance, bending resistance, fatigue resistance and toughness.
