The invention relates to durable anti-cracking commercial concrete comprising the following components in parts by weight: 190 to 370 parts of cement, 110 to 170 parts of water, 25 to 75 parts of flyash, 60 to 110 parts of mineral powder, 470 to 750 parts of a fine aggregate, 950 to 1100 parts of a coarse aggregate, 20 to 50 parts of a light aggregate composition, 2 to 12 parts of steel fibers, 2to 7 parts of epoxy resin and 3.5 to 8.5 parts of a water reducing agent, wherein the light aggregate composition is composed of the following components in parts by weight: 15 to 30 parts of spongerubber particles and 5 to 20 parts of a light aggregate. The preparation method comprises the steps: S1, uniformly mixing the light aggregate with the sponge rubber particles to obtain the light aggregate composition; and S2, firstly, adding epoxy resin into water and stirring, and then adding the light aggregate composition and the steel fibers in the step S1 into water and stirring; and finally,adding the cement, the fly ash, the mineral powder, the fine aggregate, the coarse aggregate and the water reducing agent, and stirring to obtain the durable anti-cracking commercial concrete. The durable anti-cracking commercial concrete disclosed by the invention has the effects of being strong in anti-cracking performance and improving the durability of the concrete.
本发明涉及一种耐久抗开裂商品混凝土，按重量份计，包含以下组分：水泥190‑370份，水110‑170份，粉煤灰25‑75份，矿粉60‑110份，细骨料470‑750份，粗骨料950‑1100份，轻集料组合物20‑50份，钢纤维2‑12份，环氧树脂2‑7份，减水剂3.5‑8.5份，轻集料组合物包含有以下组分：15‑30份海绵橡胶颗粒和5‑20份轻骨料；制备方法包括：S1：将轻骨料与海绵橡胶颗粒均匀混合得轻集料组合物；S2：首先，将环氧树脂加入到水中并搅拌，然后将步骤S1中的轻集料组合物和钢纤维加入到水中搅拌；最后加入水泥、粉煤灰、矿粉、细骨料、粗骨料和减水剂，搅拌得到耐久抗开裂商品混凝土。本发明的耐久抗开裂商品混凝土具有抗裂性能强，提高混凝土耐久性的效果。
