Alkali-activated slag concrete containing natural zeolite powder and preparation method thereof
The invention relates to the technical field of concrete preparation, in particular to alkali-activated slag concrete containing natural zeolite powder, which comprises the following components in parts by mass: 54-81 parts of light sand, 30-56 parts of lightweight aggregate, 38-60 parts of slag, 9-14 parts of natural zeolite powder, 5.7-9 parts of magnesium oxide powder, 0.5-2 parts of a water reducing agent, and 18-28 parts of water. The method comprises the following steps of S1, adding light sand, lightweight aggregate, slag, magnesium oxide powder and natural zeolite powder into a stirrer, and starting the stirrer to obtain a mixture, and S2, adding water and a water reducing agent into the mixture, and continuously stirring for a period of time to obtain the alkali-activated slag concrete containing natural zeolite powder. The concrete provided by the invention can effectively improve the heat resistance of traditional concrete, increase the cohesiveness of the concrete, improve the corrosion resistance of the concrete, reduce the time loss of the concrete, ensure the good pumpable performance of the concrete, improve the production efficiency, effectively reduce the dead weight of the structure and ensure the safety of the structure.
本发明涉及混凝土制备技术领域，尤其涉及一种含天然沸石粉的碱激发矿渣混凝土，包括如下质量分数的组分:轻砂54‑81份；轻骨料30‑56份；矿渣38‑60份；天然沸石粉9‑14份；氧化镁粉末5.7‑9份；减水剂0.5‑2份；水18‑28份。包括以下步骤:S1将轻砂、轻骨料、矿渣、氧化镁粉末和天然沸石粉加入到搅拌机中，启动搅拌机，得到混合料；S2向混合料中加入水和减水剂，继续搅拌一段时间，得到一种含天然沸石粉的碱激发矿渣混凝土。本发明提出的混凝土能够有效的改善传统混凝土的耐热性、增加混凝土的黏聚性、提高混凝土的抗腐蚀性、减少混凝土的经时损失,同时保证混凝土良好可泵送性能，提高生产效率，且有效减轻结构自重，保证结构安全。
