Impervious concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses impervious concrete and a preparation method thereof. The impervious concrete comprises the following components in parts by weight: 220-240 parts of cement; 720-760 parts of medium sand; 980-1100 parts of stone; 160-180 parts of water; 70-90 parts of mineral powder; 65-85 parts of fly ash; 4-5 parts of an additive; 15-20 parts of superfine silicon dioxide; 2-3 parts of choline chloride; and 6-10 parts of zeolite powder. The preparation method comprises the following steps: stirring and mixing the stones, the medium sand, the fly ash, the cement and the mineral powder, and drying to obtain a mixture; stirring and mixing the water and the additive to obtain a mixed solution; stirring and mixing the mixture and the mixed solution, then adding superfine silicon dioxide, choline chloride and zeolite powder, stirring continuously, and obtaining the impervious concrete. When free water which does not take a hydration effect in the impervious concrete evaporates, cement which is not hydrated does not exist in the impervious concrete so that pores and micro cracks are not generated in the impervious concrete, and the overall impervious performance is excellent.
本申请涉及混凝土领域，具体公开了一种抗渗混凝土及其制备方法。一种抗渗混凝土，包括如下重量份数的组分：水泥220‑240份；中砂720‑760份；石子980‑1100份；水160‑180份；矿粉70‑90份；粉煤灰65‑85份；外加剂4‑5份；超细二氧化硅15‑20份；氯化胆碱2‑3份；沸石粉6‑10份。其制备方法为：将石子、中砂、粉煤灰、水泥、矿粉在进行搅拌混合，并进行烘干，得到混合料；将水和外加剂进行搅拌混合，得到混合液；将混合料和混合液进行搅拌混合，再加入超细二氧化硅、氯化胆碱和沸石粉，不断进行搅拌，即可得到抗渗混凝土。本申请抗渗混凝中土未起水化作用的游离水蒸发时，抗渗混凝土中已不存在未水化的水泥，因此内部也不会产生毛细孔和微裂缝，整体抗渗性能优异。
