Decorative pavement slab for constructional engineering and preparation method thereof
The invention relates to the field of road reconstruction, and particularly discloses a constructional engineering decorative pavement slab and a preparation method thereof. The architectural engineering decorative pavement slab is prepared from the following raw materials in parts by weight: 800 to 1000 parts of coarse aggregate, 500 to 700 parts of fine aggregate, 250 to 350 parts of cement, 150 to 200 parts of water and 5.5 to 7.5 parts of polycarboxylic acid water reducing agent, the coarse aggregate comprises modified coarse aggregate and pebbles, the weight ratio of the modified coarse aggregate to the pebbles is 1: 1, and the modified coarse aggregate is prepared from modified coal-fired slag and modified ceramsite; the preparation method comprises the following steps: stirring and mixing the coarse aggregate, the fine aggregate and the cement, adding the water and the polycarboxylate superplasticizer, and stirring and mixing to obtain the concrete. The architectural engineering decorative pavement slab can be used for road reconstruction, and has the advantage of reducing the influence of excessive water absorption of the coal-fired slag on the concrete strength.
本申请涉及道路改造领域，具体公开了一种建筑工程装饰路面板及其制备方法。一种建筑工程装饰路面板包括以下重量份的原料：粗骨料800‑1000份，细骨料500～700份，水泥250～350份，水150～200份，聚羧酸减水剂5.5～7.5份；所述粗骨料包括改性粗骨料和石子，所述改性粗骨料和石子二者重量之比为1:1，所述改性粗骨料由改性燃煤炉渣和改性陶粒制备而来；其制备方法为：将粗骨料、细骨料和水泥搅拌混合，再加入水和聚羧酸减水剂搅拌混合制得混凝土。本申请的建筑工程装饰路面板可用于道路改建，其具有减少燃煤炉渣过量吸水对混凝土强度的影响的优点。
