Impermeable high-durability mass concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to impervious high-durability mass concrete which is prepared from the following raw materials in parts by weight: 150 to 180 parts of cement, 820 to 840 parts of stone, 60 to 80 parts of coarse sand, 30 to 50 parts of fine sand, 10 to 15 parts of fly ash, 5 to 15 parts of mixed fiber, 2 to 10 parts of hydrophobic microspheres, 0.5 to 0.8 part of water reducing agent, 0.3 to 0.6 part of air entraining agent and 150 to 170 parts of water. The preparation method of the hydrophobic microspheres comprises the following steps: S1, adding 2-3 parts by weight of metacrylic acid ester, 7-9 parts by weight of styrene, 0.3-0.6 part by weight of methacrylic acid and 0.05-0.07 part by weight of double-end vinyl polydimethylsiloxane into DMF (Dimethyl Formamide), stirring until the materials are dissolved, adding an initiator, heating for reaction, then dropwise adding divinyl benzene, trivinyl benzene or trivinyl silane, and stirring until the materials are completely dissolved; continuously reacting to obtain a mixed solution; s2, carrying out solid-liquid separation on the mixed solution to obtain hydrophobic microspheres; the anti-seepage agent has the advantage of improving the anti-seepage performance of the concrete.
本申请涉及混凝土的技术领域，具体涉及一种抗渗高耐久性大体积混凝土，其包括如下重量份的原料：水泥150‑180份、石子820‑840份、粗砂60‑80份、细砂30‑50份、粉煤灰10‑15份、混合纤维5‑15份、疏水微球2‑10份、减水剂0.5‑0.8份、引气剂0.3‑0.6份、水150‑170份；疏水微球的制备方法如下：S1、在DMF中加入2‑3重量份的甲基丙烯酸酯、7‑9重量份的苯乙烯、0.3‑0.6重量份的甲基丙烯酸与0.05‑0.07重量份的双端乙烯基聚二甲基硅氧烷，搅拌至溶解，加入引发剂，升温反应，然后滴加二乙烯基苯、三乙烯基苯或三乙烯基硅烷，继续反应，得混合液；S2、将混合液固液分离，得疏水微球；其具有提高混凝土的抗渗性能的优点。
