Wet-mixed mortar additive, preparation method and application
The invention belongs to the technical field of building materials, and particularly relates to a wet-mixed mortar additive, a preparation method and application. The wet-mixed mortar additive is prepared from the following raw materials in parts by weight: 20-25 parts of a water-retaining thickening agent, 10-15 parts of attapulgite, 3-5 parts of a defoaming agent, 3-5 parts of a stabilizer, 6-10 parts of a retarder, 5-8 parts of an anti-cracking agent and 50-60 parts of water, wherein the water-retaining thickening agent is a mixture of hydroxypropyl methyl cellulose ether, kaolin and fly ash; wherein the mass ratio of the hydroxypropyl methyl cellulose ether to the kaolin to the fly ash is 1: (25-30): (18-20). When the wet-mixed mortar additive is used for preparing the wet-mixed mortar, the consistency and the water retention rate of the wet-mixed mortar can be obviously improved, so that the prepared wet-mixed mortar can still have relatively high consistency within the construction period of 2-3 days, and construction is facilitated.
本发明属于建筑材料技术领域，具体涉及一种湿拌砂浆添加剂、制备方法及应用；所述湿拌砂浆添加剂的制备原料按重量份计包括：保水增稠剂20‑25份，凹凸棒土10‑15份，消泡剂3‑5份，稳定剂3‑5份，缓凝剂6‑10份，抗裂剂5‑8份，水50‑60份，其中保水增稠剂为羟丙基甲基纤维素醚、高岭土以及粉煤灰的混合物，其中羟丙基甲基纤维素醚、高岭土以及粉煤灰的质量比为1：25～30：18～20。本发明提出的湿拌砂浆添加剂在制备湿拌砂浆时能够明显的提高湿拌砂浆的稠度和保水率，使得制备出的湿拌砂浆在2‑3天的施工期限内仍能具备较高的稠度，从而便于施工。
