The invention discloses high-performance energy-saving foam concrete and a preparation method thereof, and relates to the technical field of concrete.The high-performance energy-saving foam concrete is prepared from, by weight, 80-100 parts of cement, 12-20 parts of filling aggregate, 1-2 parts of foaming agent, 0.5-2 parts of water reducing agent, 0.2-1 part of fiber material and 30-50 parts of water; wherein the filling aggregate is prepared by mixing and modifying fly ash, alkyl sodium sulfonate, chitosan, aluminum oxide, sodium alginate, n-propyl acetate and 4-chlorophenylboronic acid. While the compressive strength of the foam concrete is remarkably improved, the distribution and size of bubbles in the foam concrete are optimized, so that the number of foams is remarkably increased, the size of the foams is remarkably reduced, and the fly ash is combined with the chitosan under the osmotic reaction treatment of the alkyl sodium sulfonate to form a three-dimensional network structure in the prepared foam concrete; therefore, the anti-cracking capability of the foam concrete is obviously improved.
本申请公开了一种高性能节能泡沫混凝土及其制备方法，涉及混凝土技术领域，包括如下重量份的组分：80‑100份的水泥、12‑20份的填充骨料、1‑2份的发泡剂、0.5‑2份的减水剂、0.2‑1份的纤维材料以及30‑50份的水；其中：所述填充骨料由粉煤灰、烷基磺酸钠、壳聚糖、氧化铝、海藻酸钠、醋酸正丙酯以及4‑氯苯硼酸混合改性制备获得。本申请具有在显著提升泡沫混凝土抗压强度的同时，优化泡沫混凝土内的气泡分布和尺寸，使得泡沫数量显著增加和尺寸减小，且经粉煤灰在烷基磺酸钠的渗透反应处理下与壳聚糖结合在制备获得的泡沫混凝土内形成三维网状结构，从而显著提高泡沫混凝土的抗开裂能力的效果。
