Porous ecological concrete and preparation process thereof
The invention relates to the field of ecological concrete, in particular to porous ecological concrete and a preparation process thereof. Comprising the following raw materials: sulphoaluminate cement, coarse aggregate, alkali-reducing filler, fly ash, mineral slag, water, a water reducer, a retarder, carboxymethyl cellulose and an alkali-reducing treatment agent, wherein the alkali-reducing filler is ferrous sulfate and silica fume; the preparation process comprises the following steps: mixing and stirring 60-70% of the total weight of the coarse aggregate and the water, then adding 45-50% of the total weight of the gel material, adding the balance of the gel material and the water, inserting and tamping into a mold, removing the mold, and curing to obtain primary concrete; the preparation method comprises the following steps: performing primary alkali reduction treatment on primary concrete, and performing secondary alkali reduction treatment on the primary concrete subjected to the primary alkali reduction treatment by using an alkali reduction treatment agent, thereby obtaining the porous ecological concrete. The method has the advantage of reducing the alkalinity of the porous ecological concrete.
本申请涉及生态混凝土领域，更具体地说，它涉及多孔生态混凝土及其制备工艺。包括以下原料：硫铝酸盐水泥、粗骨料、降碱填料、粉煤灰、矿物渣、水、减水剂、缓凝剂、羧甲基纤维素、降碱处理剂，所述降碱填料为硫酸亚铁和硅灰；其制备工艺：将粗骨料和水总重量的60‑70%混合搅拌，然后加入凝胶材料总重量的45‑50%，加入余量的凝胶材料和水，插捣装入模具中，拆模并进行养护，制得初混凝土；将初混凝土进行第一次降碱处理，然后使用降碱处理剂对第一次降碱后的初混凝土进行第二次降碱处理，制得多孔生态混凝土。本申请其具有降低多孔生态混凝土的碱度优点。
