Concrete proportioning method and airport fabricated pavement slab manufacturing method
The invention discloses a concrete proportioning method and an airport fabricated pavement slab manufacturing method. Wherein the concrete is prepared from the following raw materials in parts by weight: 480 to 500 parts of cement, 680 to 710 parts of fine aggregate, 300 to 330 parts of coarse aggregate I, 710 to 750 parts of coarse aggregate II, 30 to 50 parts of silicon powder, 4 to 8 parts of water reducing agent and 110 to 140 parts of water; the grain size of the coarse aggregate I is larger than or equal to 5mm and smaller than or equal to 10mm, the grain size of the coarse aggregate II is larger than 10mm and smaller than or equal to 20mm, and the grain size of the fine aggregate is larger than or equal to 0.75 mm and smaller than or equal to 4.75 mm. Compared with common concrete, the concrete prepared according to the formula provided by the invention has better flexural tensile strength and wear resistance, and has strength, stability and workability. According to the material ratio of the formula, the rebound and bleeding conditions of concrete in the galling process can be reduced to the maximum extent, and firmer bonding with a base layer is formed, so that the galling time is prolonged, the galling quality is improved, the anti-skid performance requirement of an airport is met, and the formula is more suitable for producing the assembled pavement of the airport.
本发明公开了一种混凝土配比及机场装配式道面板制作方法。其中混凝土配比包括如下重量份的原料：水泥480～500份、细骨料680～710份、粗骨料Ⅰ300～330份、粗骨料Ⅱ710～750份、硅粉30～50份、减水剂4～8份、水110～140份；所述粗骨料Ⅰ的粒径为：5mm≤粗骨料Ⅰ≤10mm，所述粗骨料Ⅱ的粒径为：10mm＜粗骨料Ⅱ≤20mm，所述细骨料的粒径为：0.75mm≤细骨料≤4.75mm。使用本发明提供的配方配比混凝土，该混凝土相较于普通混凝土抗弯拉强度和耐磨性更好，兼顾了强度、稳定性和工作性。本配方的材料配比，可以最大限度减少拉毛过程中混凝土的反弹和泌水情况，与基层形成了更牢固的黏结，从而延长了拉毛时间，提高了拉毛质量，满足了机场抗滑性能要求，更加适用于生产机场装配式道面。
