混凝土修补工程,在经济困难时期可能成为建筑部门唯一发展较快的新兴行业。如果在施工期对原材料熟悉并加以合理使甩,则可避免许多修补工作。虽然,任何部位的混凝土修补都可采用水泥砂浆,但在一些工程实例中,用聚合物作为水泥砂浆的掺合剂或高强度的粘结剂(如粘结料、灰浆和砂浆),则更为实用。二十多年来各种聚合物已广泛地应用于建筑物的维修和保养,毫无疑问,在混凝土修补中
The concrete repair project may become the only emerging industry in the construction sector that develops rapidly during difficult economic times. If you are familiar with raw materials during the construction period and make reasonable use of them, many repairs can be avoided. Although cement mortar can be used for concrete repair at any site, in some engineering examples, polymers are used as cement mortar admixtures or high-strength binders (such as binders, mortars and mortars). practical. For more than two decades, various polymers have been widely used for the repair and maintenance of buildings. There is no doubt that in concrete repairs
