High-strength impermeable concrete and preparation method thereof
The invention discloses high-strength impermeable concrete and a preparation method thereof. According to the technical scheme, the high-strength impermeable concrete is prepared from the following components in parts by weight: 360 to 380 parts of cement, 20 to 30 parts of fly ash, 90 to 110 parts of slag powder, 40 to 50 parts of an expanding agent, 650 to 700 parts of a fine aggregate, 1030 to1070 parts of a coarse aggregate, 10 to 12 parts of an additive and 150 to 160 parts of water; the expanding agent is a calcium oxide expanding agent; the aggregate is in six gradations, the coarse aggregate is in four gradations, and the fine aggregate is in two gradations. According to the invention, the six-graded aggregate can be stacked to form a densely-filled lap joint skeleton, and concrete strength is increased; through cooperation of the calcium oxide expanding agent, after the concrete is hardened, enough plastic expansion and certain later-period expansion can be provided for the concrete, so that the expanding agent can continuously expand to improve the compactness of the concrete, and the impermeability of the concrete is improved.
本发明公开了一种高强抗渗混凝土及其制备方法，其技术方案要点是一种高强抗渗混凝土，以重量份数计，包括如下组分：水泥360‑380份、粉煤灰20‑30份、矿渣粉90‑110份、膨胀剂40‑50份、细骨料650‑700份、粗骨料1030‑1070份、外加剂10‑12份以及水150‑160份；所述膨胀剂为氧化钙类膨胀剂；骨料为六级配,其中粗骨料为四级配，细骨料为两级配。本发明通过采用六级配的骨料可以堆积形成密实填充的搭接骨架，提高混凝土的强度，通过氧化钙类膨胀剂的配合，在混凝土硬化后，可以为其提供足够的塑性膨胀以及一定的后期膨胀，使得膨胀剂可以持续膨胀，以提高混凝土致密性，从而提高混凝土的抗渗性能。
