HPMC-floating bead composite lightweight high-strength foam concrete and preparation method thereof
The invention belongs to the technical field of foam concrete, and discloses HPMC-floating bead composite light-weight high-strength foam concrete and a preparation method thereof, and the foam concrete comprises the following components in parts by weight: 800-1600 parts of cement, 720-1500 parts of water, 360-800 parts of fly ash, 90-540 parts of floating beads, 54-140 parts of silica fume, 2-16 parts of fibers, 4-8 parts of a water reducing agent, 2-8 parts of a thickening agent, 8-16 parts of calcium stearate and 90-630 parts of foam. Industrial waste residues such as floating beads, fly ash and silica fume are used as filling materials of foam concrete, so that the physical strength and thermal insulation performance of the foam concrete material are improved, the cement consumption is greatly reduced, the environmental pollution rate is reduced, and the energy utilization rate is improved. Besides, on the basis that the floating beads are added, hydroxypropyl methyl cellulose is used as a thickening agent, so that the dispersity of the floating beads and the bonding strength of the floating beads and cement are improved, and the effect of improving the structure and the mechanical property of the foam concrete is further achieved.
本发明属于泡沫混凝土技术领域，公开了一种HPMC‑漂珠复合轻质高强泡沫混凝土及其制备方法，且该泡沫混凝土包括如下重量份组分：水泥800～1600份、水720～1500份、粉煤灰360～800份、漂珠90～540份、微硅粉54～140份、纤维2～16份、减水剂4～8份、增稠剂2～8份、硬脂酸钙8～16份、泡沫90～630份。本发明利用漂珠、粉煤灰、微硅粉等工业废渣用于充当泡沫混凝土的填充材料，从而提高泡沫混凝土材料的物理强度和保温性能，并且极大的减少水泥用量、降低环境污染率和提高能源的利用。另外，在添加漂珠的基础上，还以羟丙基甲基纤维素作为增稠剂，以此提高漂珠的分散度以及其与水泥的粘接强度，进而达到改善泡沫混凝土结构及力学性能的效果。
