变截面大体积混凝土裂缝控制技术的应用

Application of Crack Control Technology in Different Section Mass Concrete

根据变截面大体积混凝土的特点,提出了原材料的选择和配合比的设计方法,利用聚丙烯纤维来提高混凝土的抗裂性能,确立混凝土的浇筑与养护技术。通过质量检测,结构未发现缺陷。这些方法解决了变截面大体积混凝土易出现裂缝的问题。

According to the characteristic of different section mass concrete,authors put forward design method for raw materials selection and mix ratio,improving concrete anti-crack performance by polypropylene fiber and concrete pouring and curing technology.By quality inspection,concrete structure has no defects which proves that these methods can solve crack problem of different section mass concrete.
