Preparation process of slip-form construction concrete
The invention discloses a slip-form construction concrete preparation technology, and relates to the technical field of slip-form construction, the preparation method comprises the following steps: S1, selecting raw materials; s2, crushing the materials; s3, primary mixing; s4, performing secondary mixing; s5, mixing for the third time; the sepiolite fibers can effectively control microcracks caused by factors such as plastic shrinkage, dry shrinkage and temperature change of the concrete, prevent and inhibit formation and development of primary cracks of the concrete, greatly improve the anti-cracking, anti-seepage and anti-abrasion performance of the concrete, and increase the toughness of the concrete, so that the service life of the concrete is prolonged, and the concrete is suitable for popularization and application. The production cost of the concrete is reduced by adopting the fly ash, the silicon powder and the mineral powder, the use strength of the concrete is improved through reasonable preparation steps, and the water-based fluorocarbon emulsion resin can prolong the hydration hardening time of cement, so that the newly mixed concrete can keep plasticity for a long time, and the setting time of the newly mixed concrete is adjusted.
本发明公开了一种滑模施工混凝土制备工艺，涉及滑模施工技术领域，制备方法为：S1、选取原料；S2、材料破碎；S3、一次混合；S4、二次混合；S5、三次混合；S6、静置，海泡石纤维能有效地控制混凝土塑性收缩、干缩、温度变化等因素引起的微裂纹，防止及抑制混凝土原生裂缝的形成和发展，大大改善混凝土的防裂抗渗性能、抗冲磨性能，增加混凝土的韧性，从而提高混凝土的使用寿命，采用的粉煤灰、硅粉、矿粉降低了混凝土的生产成本，通过合理的制备步骤，提高混凝土的使用强度，水性氟碳乳液树脂能够延长水泥的水化硬化时间，使新拌混凝土能在较长时间内保持塑性，从而调节新拌混凝土的凝结时间。
