Heat storage foam concrete and preparation method thereof
The invention relates to heat storage foam concrete and a preparation method thereof, and the heat storage foam concrete is prepared from the following raw material composition in parts by weight: 450-900 parts of cement, 200-400 parts of an auxiliary cementing material, 50-100 parts of a phase change material, 150-300 parts of water, 2-4 parts of a water reducing agent, 0.1-0.2 part of a thickening agent, 4-6 parts of plant fiber and 12-28 parts of foam. The invention has the following beneficial effects: the flaky phase-change material is directly mixed with concrete, foam and other materials, the step of packaging the phase-change material is omitted, the heat storage effect of the phase-change material is improved, the expanded vermiculite is selected as the carrier of the phase-change material, the bonding strength of the interface between foam concrete is enhanced, and the heat storage effect of the phase-change material is improved. Therefore, the effect of improving the strength of the foam concrete is achieved.
本发明涉及一种储热泡沫混凝土及其制备方法，其中，储热泡沫混凝土，其由包括按重量份计的如下原料组合物制成：水泥450～900份、辅助性胶凝材料200～400份、相变材料50～100份、水150‑300份、减水剂2～4份、增稠剂0.1‑0.2份、植物纤维4～6份和泡沫12～28份。其有益效果是，采用片状的相变材料直接与混凝土、泡沫等材料进行混合，省去封装相变材料的步骤，提高了相变材料的蓄热效果，选用膨胀蛭石作为相变材料的载体，增强了泡沫混凝土之间界面的结合强度，从而达到了提高泡沫混凝土强度的作用。
