Durable concrete
The invention belongs to the technical field of concrete, and particularly relates to durable concrete which is prepared from the following components in parts by weight: 300 to 400 parts of cement, 450 to 550 parts of fine aggregate, 720 to 820 parts of coarse aggregate, 100 to 200 parts of water, 20 to 40 parts of fiber, 20 to 40 parts of polymer emulsion and 10 to 20 parts of polycarboxylate superplasticizer. According to the durable concrete, the flexible fibers are added into the base material, the impact toughness of the concrete material can be enhanced, the effective anti-cracking and anti-seepage effects are achieved, in addition, the added polycarboxylate superplasticizer has a phenyl salicylate structure capable of absorbing ultraviolet rays, and the ultraviolet ray absorbing structure is bonded in the polycarboxylate superplasticizer, the conditions of migration, precipitation and the like of a micromolecular ultraviolet light absorber are not easy to occur, so that a long-term anti-aging effect can be achieved, and the durability of the concrete is improved.
本申请属于混凝土技术领域，具体涉及一种耐久性混凝土，包括如下重量份的各组分：水泥300‑400份、细骨料450‑550份、粗骨料720‑820份、水100‑200份、纤维20‑40份、聚合物乳液20‑40份、聚羧酸减水剂10‑20份。本申请的耐久性混凝土，通过在基料中添加柔性纤维，可以增强混凝土材料的抗冲击韧性，起到有效的防裂防渗作用，另外，所添加的聚羧酸减水剂中具有可吸收紫外线的邻羟基苯甲酸苯酯结构，该紫外线吸收结构是键合在聚羧酸减水剂中，不易像小分子的紫外线吸收剂一样发生迁移、析出等情况，从而可以起到长久的抗老化作用，提高混凝土的耐久性。
