Dam face splicing material and preparation method thereof
The invention relates to the field of concrete, and particularly discloses a dam face splicing material and a preparation method thereof. The dam surface splicing material comprises cement, coarse aggregate, fine aggregate, fly ash, reinforced fibers, an anti-cracking agent, tap water and a water reducing agent, wherein the anti-cracking agent comprises polyethyl methacrylate, sodium octyl sulfonate, silica fume and guar gum; the preparation method comprises the following steps: respectively putting the coarse aggregate and the fine aggregate into a stirrer for full dry mixing; adding the cement and the fly ash into a stirrer, adding 50% of tap water, and carrying out wet mixing with the mixed aggregate; and adding the reinforced fibers, the anti-cracking agent and the water reducing agent into the mixture, adding 50% of tap water, and continuously stirring for 10-30 minutes to obtain the dam surface splicing material. The dam face splicing material has the advantage that the problem of leakage caused by cracking of the concrete face is effectively solved.
本申请涉及混凝土领域，具体公开了一种坝面拼接材料及其制备方法。坝面拼接材料包括水泥、粗骨料、细骨料、粉煤灰、增强纤维、抗裂剂、自来水和减水剂，所述抗裂剂包括聚甲基丙烯酸乙酯、辛基磺酸钠、硅灰和瓜尔豆胶；其制备方法为：将粗骨料和细骨料分别放入搅拌机中进行充分的干混；将水泥和粉煤灰加入到搅拌机中加入50%的自来水，与混合的骨料一起进行湿混；将增强纤维、抗裂剂和减水剂添加到混合物中，加入50%自来水，继续搅拌10‑30min，得到坝面拼接材料。本申请的坝面拼接材料具有有效解决混凝土面板因开裂而引起的渗漏问题的优点。
