Energy-saving concrete for buildings and preparation process thereof
The invention discloses energy-saving concrete for buildings and a preparation process thereof. The energy-saving concrete for buildings comprises the following raw materials in parts by weight: 80-120 parts of a cementing material, 30-50 parts of sand, 8-12 parts of modified aggregate, 10-14 parts of an excitant, 3-5 parts of a water reducing agent, 3-5 parts of a foaming agent and 12-14 parts ofpolyester fiber extraction waste liquid. According to the preparation process of the energy-saving concrete for the building, the continuity and stability of excitation of sodium sulfate to mineral admixtures are maintained by utilizing sodium sulfate, the absorption capacity of a hydration system to Ca (OH) 2 is accelerated by doping sodium sulfate, the depolymerization and dissolution of vitreous bodies in fly ash and mineral powder are accelerated by the existence of alkali, and the fly ash and mineral slag are promoted to participate in hydration reaction; more CSH gel is generated, so that the strength of the concrete block is improved, and finally, the aggregate is subjected to modification treatment, and triethanolamine is used for modifying the surface of polystyrene, so that themechanical property of concrete is effectively improved.
本发明公开了一种建筑用节能混凝土及其制备工艺，建筑用节能混凝土的原料按重量份包括胶凝材料80‑120份、砂料30‑50份、改性骨料8‑12份、激发剂10‑14份、减水剂3‑5份、发泡剂3‑5份和聚酯纤维提取废液12‑14份。该建筑用节能混凝土的制备工艺，利用硫酸钠保持硫酸钠对矿物掺合料激发的连续性与稳定性，硫酸钠的掺入加速了水化体系对Ca(OH)2的吸收能力，碱的存在加速了粉煤灰，矿粉中玻璃体的解聚和溶解，促进了粉煤灰，矿渣参与水化反应，生成更多的C‑S‑H凝胶，使得混凝土砌块的强度得到提高，最后通过对骨料进行改性处理，使用三乙醇胺对聚苯乙烯的表面进行改性，有效提高混凝土的力学性能。
