Production method suitable for light-colored UHPC decorative products
The invention discloses a production method suitable for light-colored UHPC decorative products. The production method comprises the following steps that the first-pass concrete is prepared for lateruse; the slurry of the stirred first-pass concrete is poured into a mold so that the first-pass concrete is completely spread in the mold, the thickness is easily controlled to be 2-5 mm, and vibration is sufficient until no bubble floats up and is stopped; the second-pass concrete is prepared for later use; and the second-pass concrete is stirred and poured on the first-pass concrete, and the second-pass concrete is spread in the mold, the interval time between two times of pouring is controlled to be 20-30 min, and curing and demolding are carried out. According to the production method, through the method of two-time casting forming, small bubbles on the surface of the product can be eliminated and the problem of poor surface uniformity effect caused by sinking of the steel fiber can beavoided at the same time, and the product with uniform color, no small bubble and good appearance can be obtained.
本发明公开了一种适用于浅色系UHPC装饰制品的生产方法，包括以下步骤：配制第一遍混凝土，备用；将搅拌后的第一遍混凝土的浆料倒入模具中，使其完全铺满在模具中，厚度易控制在2~5mm，充分振动待不再有气泡上浮停止；配制第二遍混凝土，备用；第二遍混凝土搅拌后倒入第一遍混凝土之上，平铺在模具中，两遍浇筑的间隔时间控制在20~30min，养护脱模。本发明方法通过两次浇筑成型的方法，可以消除制品表面的小气泡同时避免由于钢纤维下沉造成的表面效果均匀性差的问题，能够得到颜色均匀、无小气泡、外观好的制品。
