Large-flow-state light-weight high-strength EPS concrete and preparation method thereof
The invention provides large-flow-state light-weight high-strength EPS concrete and a preparation method thereof, and belongs to the technical field of concrete. The invention relates to a large-flow-state light-weight high-strength EPS (Expandable Polystyrene) concrete, which is prepared from the following components in parts by weight: 350 to 400 parts of cement, 100 to 150 parts of fly ash, 70 to 120 parts of limestone powder, 90 to 140 parts of quartz sand, 80 to 140 parts of glass beads, 1 to 2 parts of polyphenyl granules, 0.05 to 0.1 part of air entraining agent, 1 to 3 parts of fiber, 0.05 to 0.15 part of thickening agent, 1.5 to 4.5 parts of rubber powder, 0.3 to 0.6 part of waterproof agent, 3 to 6 parts of water reducing agent and 150 to 200 parts of water. The air entraining agent comprises fatty alcohol sulfonates and sodium alpha-olefin sulfonate. The invention further provides a preparation method of the large-flow-state light-weight high-strength EPS concrete. A proper amount of the air entraining agent, the EPS particles and the glass beads are added into the concrete, the purpose of reducing the density of the slurry is achieved, and the slurry has super-large fluidity, good workability, low apparent density, high compressive strength, low water absorption and excellent thermal insulation performance. The material can be used for manufacturing external wallboards, internal wallboards, floor slabs, roof panels, insulation boards and the like.
本发明提供一种大流态轻质高强EPS混凝土及其制备方法，属于混凝土技术领域。一种大流态轻质高强EPS混凝土，按重量份计包含水泥350‑400份、粉煤灰100‑150份、石灰石粉70‑120份、石英砂90‑140份、玻化微珠80‑140份、聚苯颗粒1‑2份、引气剂0.05‑0.1份、纤维1‑3份、增稠剂0.05‑0.15份、胶粉1.5‑4.5份、防水剂0.3‑0.6份、减水剂3‑6份、水150‑200份，所述引气剂包含脂肪醇磺酸盐类、α‑烯基磺酸钠。本发明还提供一种大流态轻质高强EPS混凝土的制备方法。本发明中通过在混凝土中添加适量的引气剂、EPS颗粒、玻化微珠，实现降低浆料密度的目的，浆料具有超大的流动性、良好的和易性、较低的表观密度、较高的抗压强度、较低的吸水率和优异的保温性能。可用于制作外墙板、内墙板、楼板、屋面板和保温板等。
