Anti-knock concrete for protective engineering and production method of anti-knock concrete
The invention relates to anti-explosion concrete for protective engineering and a production method of the anti-explosion concrete, and belongs to the field of concrete. Each cubic meter of the anti-explosion concrete for the protective engineering is prepared from the following components: 300 to 400kg of moderate heat or low heat cement, 250 to 350kg of multifunctional admixture, 700 to 900kg of fine aggregate, 800 to 1100kg of coarse aggregate, 5 to 20kg of organic fiber, 25 to 200kg of metal fiber, 5 to 15kg of water reducing agent, 1 to 5kg of defoaming agent, 1 to 8kg of hydration heat inhibitor and 2 to 6kg of shrinkage reducing agent. According to the invention, a low-heat rubber material system composed of the multifunctional admixture and the medium-low-heat cement is adopted, the hydration heat inhibitor reduces the hydration heat release amount of the concrete and improves the crack resistance, and the admixture is supplemented to realize the self-compacting performance; organic and metal fibers are mixed, so that strength, toughness and high-temperature resistance are improved, anti-explosion, anti-penetration and high-temperature burst resistance are improved, and then the thickness and construction difficulty of the anti-explosion protection structure are reduced.
本发明涉及一种防护工程用抗爆混凝土及其生产方法，属于混凝土领域。该防护工程用抗爆混凝土每立方米其组分包括：中热或低热水泥300‑400kg，多功能掺合料250‑350kg，细骨料700‑900kg，粗骨料800‑1100kg，有机纤维5‑20kg，金属纤维25‑200kg，减水剂5‑15kg，消泡剂1‑5kg，水化热抑制剂1‑8kg，减缩剂2‑6kg。本发明采用多功能掺合料和中低热水泥构成的低热胶材体系、水化热抑制剂降低混凝土水化放热量，提高抗裂性能，辅以外加剂实现自密实性能；有机与金属纤维混杂提升了强度、韧性及耐高温能力，改善抗爆抗侵彻及高温抗爆裂性，进而减小抗爆防护结构的厚度和施工难度。
