Perlite-based ecological concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, and particularly discloses perlite-based ecological concrete and a preparation method thereof. The perlite-based ecological concrete is mainly prepared from the following raw materials: cement, recycled coarse aggregate, recycled fine aggregate, an additive, water, expanded perlite, a water permeable agent and porous expanded vermiculite, and the water permeable agent is prepared from modified fluorinated silicone rubber, carbon fibers and tetrapod-like zinc oxide whiskers; the preparation method comprises the following steps: mixing the recycled coarse aggregate, the recycled fine aggregate, the additive, the expanded perlite, the water permeable agent and the porous expanded vermiculite to obtain a premix; and mixing the water, the cement and the premix to obtain the cement. The perlite-based ecological concrete prepared by the invention is relatively good in permeability coefficient and compressive strength.
本申请涉及混凝土制备技术领域，具体公开了一种珍珠岩基生态型混凝土及制备方法。本申请的珍珠岩基生态型混凝土，主要由如下原料制成：水泥、再生粗骨料、再生细骨料、外加剂、水、膨胀珍珠岩、透水剂、多孔膨胀蛭石，透水剂由改性氟硅橡胶、碳纤维、四针状氧化锌晶须组成；制备方法，包括如下步骤：将再生粗骨料、再生细骨料、外加剂、膨胀珍珠岩、透水剂、多孔膨胀蛭石混合，得到预混物；将水、水泥、预混物混合，即得。本申请制得的珍珠岩基生态型混凝土的透水系数和抗压强度均较佳。
