High-ductility cement-based material, preparation method thereof and raised floor
The invention discloses a high-ductility cement-based material, a preparation method thereof and a raised floor, and belongs to the technical field of building materials. According to the key point of the technical scheme, the cement-based material is prepared from the following raw materials in parts by weight: 100 to 400 parts of cement, 100 to 600 parts of active brick micro powder, 100 to 1000 parts of fine aggregate, 300 to 500 parts of water, 2 to 5 parts of water reducing agent, 1 to 3 parts of reinforcing agent, 1 to 5 parts of redispersible latex powder, 1 to 10 parts of heat-resistant filler and 5 to 15 parts of fiber. The active brick micro-powder is prepared by the following preparation method: crushing and screening waste bricks to obtain waste brick particles with the particle size of less than 5mm, drying 100-600 parts by weight of waste brick particles at 105 DEG C for 30-60 minutes, then cooling for 30-40 minutes, and crushing the waste brick particles to obtain the active brick micro-powder. And grinding the waste brick particles and 0.5-1.5 parts by weight of an aluminum-based exciting agent for 20-40 minutes under the condition that the rotating speed is 30-50 revolutions per minute, and screening to obtain the active brick micro-powder. The effect of overcoming the defect that the ECC material is easier to generate brittle cracking at high temperature is achieved.
本发明公开了一种高延性水泥基材料及其制备方法和架空地板，属于建筑材料技术领域，其技术方案要点是所述水泥基材料包括以下重量份的原料：水泥100‑400份、活性砖微粉100‑600份、细骨料100‑1000份、水300‑500份、减水剂2‑5份、增强剂1‑3份、可再分散乳胶粉1‑5份、耐热填料1‑10份、纤维5‑15份；所述活性砖微粉由以下制备方法获得：废砖经破碎筛分得到粒径小于5mm的废砖颗粒，将100‑600重量份废砖颗粒在温度为105℃的条件下烘30‑60min，然后冷却30‑40min后，将废砖颗粒与0.5‑1.5重量份的铝基激发剂在转速为30‑50转/分钟的条件下粉磨20‑40min后筛分得到活性砖微粉，达到克服了ECC材料在高温下更容易出现脆性开裂的效果。
