Large-volume concrete, preparation method and construction process thereof
The invention provides large-volume concrete, and relates to the technical field of concrete. The large-volume concrete comprises the following components by weight: 280-310 parts of cement, 80-140 parts of fly ash, 650-800 parts of fine aggregate, 1050-1150 parts of coarse aggregate, 3-6 parts of an additive, and 155-165 parts of water. According to the invention, the components and proportions of the large-volume concrete are matched and set, so that the obtained components are more optimized; particularly, the fluidity of the prepared large-volume concrete is stronger by matching the additive; in the preparation process of the large-volume concrete, the temperature change degree is smaller by controlling the temperature of the raw materials, so that the influence of temperature on the large volume is reduced; the construction process is monitored and the temperature is detected in time in the construction process, so that the influence of the temperature on the large-volume concrete is avoided; and the large-volume concrete provided by the invention is subjected to multi-aspect and multi-level optimization control from the raw materials, the preparation method and the construction process, so that the probability of cracks is finally reduced so as to improve the overall stability and safety.
本发明提供一种大体积混凝土，涉及混凝土的技术领域，包括以下组分，按重量份计：水泥280‑310份，粉煤灰80‑140份，细骨料650‑800份，粗骨料1050‑1150份，外加剂3‑6份，水155‑165份。本发明通过搭配设置大体积混凝土的各成分以及比例，使其能够得到成分更优化，尤其是通过搭配外加剂，使其制备出的大体积混凝土的流动性更强，除此之外，在制备大体积混凝土中，通过控制原料温度，使其制备过程中温度变化程度较小，减少温度对大体积的影响，在施工过程中及时监控施工过程，检测温度，避免温度对大体积混凝土的影响，本发明所提供的大体积混凝土通过从原料、制备方法以及施工工艺多方面多层次的优化控制，从而达到最终减少出现裂缝的概率，进而提高整体的稳定性和安全性。
