Expressway concrete water reducing agent
The invention provides an expressway concrete water reducing agent. The expressway concrete water reducing agent is prepared from the following formula components in parts by mass: 27 to 33 parts of water reducing mother liquor, 38 to 48 parts of slump-retaining mother liquor, 2 to 5 parts of retarder, 0 to 0.2 part of air entraining agent, 0 to 0.05 part of defoaming agent and 13.75 to 33 parts of water. The preparation method comprises the following steps: adding the retarder into water, carrying out full stirring until the retarder is completely dissolved, then adding water to reach the required water amount, sequentially adding the water-reducing mother liquor and the slump-retaining mother liquor, performing stirring uniformly for 30 minutes, adding the defoaming agent, performing stirring uniformly for 5 minutes, finally adding the air entraining agent, and performing stirring uniformly for 10 minutes. The expressway concrete water reducing agent provided by the invention has theadvantages that the water reducing rate reaches up to 35 percent, the wrapping property is high, and the use requirements of concrete required by expressways are met.
本申请提供了一种高速公路混凝土减水剂,配方组分以质量份数计包括:减水母液27‑33份、保坍母液38‑48份、缓凝剂2‑5份、引气剂0‑0.2份、消泡剂0‑0.05份、水13.75‑33份。其制备方法包括如下步骤:将缓凝剂加入水中进行充分搅拌直至完全溶解,接着加水达到所需水量,依次加入减水母液和保坍母液,均匀搅拌30分钟,加入消泡剂,均匀搅拌5分钟,最后加入引气剂均匀搅拌10分钟后即可制得。本申请提供的一种高速公路混凝土减水剂减水率高达35%,且包裹性好,满足高速公路所需混凝土的使用要求。
