High-durability anti-erosion concrete for transformer substation foundation construction and construction method of high-durability anti-erosion concrete
The invention relates to the technical field of concrete, and particularly discloses high-durability anti-erosion concrete for transformer substation foundation construction and a construction method of the high-durability anti-erosion concrete. A mixture of the high-durability anti-erosion concrete is prepared from the following components in parts by weight: 1040 to 1080 parts of coarse aggregate, 780 to 800 parts of fine aggregate, 280 to 300 parts of Portland cement, 60 to 80 parts of mineral admixture, 30 to 50 parts of modified basalt fiber, 3.4 to 3.8 parts of polycarboxylate superplasticizer and 122 to 126 parts of water, wherein the modified basalt fiber is basalt fiber of which the surface is grafted with an acrylic polymer. Compared with common concrete, the high-durability anti-erosion concrete provided by the invention can achieve a better protection effect on permeation of chloride ions in the presence of stray current, and is beneficial to long-term service of a transformer substation foundation.
本申请涉及混凝土技术领域，具体公开了一种用于变电站基础施工的高耐久抗侵蚀混凝土及其施工方法。所述高耐久抗侵蚀混凝土的拌和物包括如下重量份的组分：粗骨料1040‑1080份，细骨料780‑800份，硅酸盐水泥280‑300份，矿物掺合料60‑80份，改性玄武岩纤维30‑50份，聚羧酸减水剂3.4‑3.8份，水122‑126份，所述改性玄武岩纤维为表面接枝有丙烯酸聚合物的玄武岩纤维。本申请的高耐久抗侵蚀混凝土与普通混凝土相比，在杂散电流存在的情况下能够对氯离子的渗透起到更好的防护效果，有利于变电站基础的长期服役。
