Preparation method of externally coated beautifying agent for improving surface uniformity of concrete
The invention discloses a preparation method of an externally-coated beautifying agent for improving the surface uniformity of concrete, and the externally-coated beautifying agent for improving the surface uniformity of the concrete is prepared from the following components in parts by weight: 21-24 parts of zeolite powder, 2-4 parts of a water reducing agent, 10-12 parts of fly ash, 0.5-1.5 parts of a defoaming agent, 4-6 parts of water glass, 0.5-0.6 part of a sizing material, 6-9 parts of anhydrite and 1-2 parts of polypropylene fiber. And 8-10 parts of quartz powder. The invention has the following advantages: the zeolite powder component effectively reduces laitance on the surface of concrete, reduces conditions for generating bubbles on the surface of concrete, effectively reduces the generation of irregular large bubbles and elliptical bubbles on the surface of concrete, effectively improves the workability of concrete, reduces the water consumption per unit by using the water reducer, improves the fluidity of a concrete mixture, and improves the durability of concrete. The defoaming agent reduces the surface tension of liquid on the surface of the concrete and prevents foam formation, the water glass improves the strength and cohesive force of the admixture, irregular large bubbles and elliptical bubbles on the surface of the concrete are effectively reduced through cooperation, and the uniformity of the surface of the concrete is effectively improved.
本发明公开了一种提高混凝土表面均匀度的外涂美化剂制备方法，提高混凝土表面均匀度的外涂美化剂以重量计，包括以下组分，沸石粉21‑24份，减水剂2‑4份，粉煤灰10‑12份，消泡剂0.5‑1.5份，水玻璃4‑6份，胶料0.5‑0.6份，硬石膏6‑9份，聚丙烯纤维1‑2份，石英粉8‑10份。本发明的优点在于，沸石粉成分有效减少混凝土表面的浮浆，减少混凝土表面气泡产生的条件，有效减少混凝土表面不规则大气泡和椭圆气泡的产生，有效改善混凝土的和易性，减水剂减少单位用水量，改善混凝土拌合物的流动性，消泡剂降低混凝土表面液体的表面张力，防止泡沫形成，所述水玻璃提高本外加剂的强度和粘聚力，共同配合有效减少混凝土表面不规则大气泡和椭圆气泡的产生，有效提高混凝土表面的均匀度。
