Preparation method and construction process of concrete for water conservancy project diaphragm wall
The invention relates to the field of water conservancy projects, in particular to a preparation method and a construction process of concrete for a water conservancy project diaphragm wall. The anti-seepage effect of the plastic concrete is enhanced by adding the polycarboxylic acid water reducer and the polypropylene fiber, controlling the particle size of the raw materials and scientifically regulating and controlling the proportion of the coarse aggregate, the fine aggregate, the fly ash and the clay, the service life of the plastic concrete is prolonged, the mechanical performance of the plastic concrete is improved, and the anti-cracking performance of the plastic concrete is improved.
本发明涉及水利工程领域，具体的涉及一种水利工程防渗墙用混凝土制备方法及施工工艺，在塑性混凝土中加入石英玻璃粉末，通过加入聚羧酸减水剂、聚丙烯纤维和控制原料粒径等方式以及科学调控粗骨料、细骨料、粉煤灰、黏土的配比掺入，增强塑性混凝土的防渗效果，有助于延长产品使用寿命，改善产品机械性能，提高产品抗裂性能。
