High-strength anti-crack environment-friendly concrete and preparation process thereof
The invention provides high-strength anti-cracking environment-friendly concrete and a preparation process thereof. The recycled concrete is prepared from the following components in parts by mass: 350 to 480 parts of PC42.5 cement, 50 to 150 parts of fly ash, 450 to 600 parts of recycled lightweight aggregate, 120 to 180 parts of coated sponge iron, 5 to 20 parts of fluorocarbon modified polyacrylamide copolymer, 40 to 70 parts of sodium bicarbonate, 60 to 120 parts of polyphenyl granules, 1 to 2.5 parts of polycarboxylic acid water reducing agent and 160 to 250 parts of mixing water, wherein the recycled lightweight aggregate comprises waste ceramsite concrete blocks and waste rock wool boards, and the coated sponge iron comprises sponge iron, borax, a polyvinyl alcohol solution and rice husks; through optimization of raw material selection and matching and application of the recycled aggregate, the concrete is green and environment-friendly, prefabricated activation components are specifically arranged, the synergistic effect, high strength, crack resistance and mechanical properties are obviously improved, the performance is lasting and stable, and the method is worthy of popularization and application.
本发明提出了一种高强抗裂环保混凝土及其制备工艺，该再生混凝土包括以下质量份数组分：PC42.5水泥350‑480份、粉煤灰50‑150份、再生轻骨料450‑600份、包覆型海绵铁120‑180份、氟碳改性聚丙烯酰胺共聚物5‑20份、碳酸氢钠40‑70份、聚苯颗粒60‑120份、聚羧酸减水剂1‑2.5份、拌合水160‑250份，其中，再生轻骨料包括废弃陶粒混凝土块、废弃岩棉板，包覆型海绵铁包括海绵铁、硼砂、聚乙烯醇溶液、稻壳；本申请通过优化原料选配，应用再生骨料，绿色环保，并针对性配设预制活化组分，协配作用，高强抗裂，力学性能明显改善，且性能持久稳定，值得推广应用。
