Non-autoclaved concrete admixture, cement mixture, concrete material, concrete product and preparation method
The invention provides a non-autoclaved concrete admixture, a cement mixture, a concrete material, a concrete product and a preparation method, and relates to the technical field of concrete. The non-autoclaved concrete admixture provided by the invention comprises active silicon oxide micro-powder and natural anhydrite, and the mass ratio of the active silicon oxide micro-powder to the natural anhydrite is 1: 9-9: 1. According to the non-autoclaved concrete admixture provided by the invention, through mutual cooperation of the active silica powder and the natural anhydrite, the activity is remarkably improved, a large amount of dicalcium silicate and tricalcium silicate can be generated in the hydration process of a concrete material after cement is equivalently replaced according to the proportion of 5wt%-10wt%, and the early strength of a concrete product is remarkably improved; and meanwhile, the continuous increase of the strength of the concrete product can be ensured by adopting natural curing in the later period, the transportation cost is reduced, the preparation process of the concrete product is simplified, and lots of manpower and material resources are saved.
本发明提供了一种免蒸压混凝土掺和料、水泥混合物、混凝土材料、混凝土制品及制备方法，涉及混凝土技术领域。本发明提供的免蒸压混凝土掺和料，包括活性氧化硅微粉和天然硬石膏，所述活性氧化硅微粉和天然硬石膏的质量比为1:9‑9:1。本发明提供的免蒸压混凝土掺和料通过活性氧化硅微粉和天然硬石膏相互协同，活性显著提高，按照5wt％‑10wt％比例等量替换水泥后，即可在混凝土材料水化过程中生成大量的硅酸二钙和硅酸三钙，显著提高混凝土制品早期强度，同时后期采用自然养护即可保证混凝土制品强度的持续增长，不仅降低了运输成本，而且简化了混凝土制品的制备工艺，节约了大量的人力物力。
