Wet-mixed mortar admixture and preparation method thereof
A wet-mixed mortar admixture is composed of the following components in percentage by weight: 1 to 5 percent of a water reducing agent, 0.1 to 1.0 percent of a water retaining agent, 5 to 15 percent of a plastic retaining time regulator, 1 to 4 percent of an air entraining agent, 0.1 to 0.3 percent of a viscosity regulator and the balance being water. According to the wet-mixed mortar admixture disclosed by the invention, all the raw material components are reasonably configured; the obtained admixture can effectively enhance the constructability and durability of mortar, prolong the plastic retaining time of the mortar to 12-48 h, improve the problems of hollowing, cracking and the like which are easily caused by plastering mortar, effectively enhance the water retention rate of the mortar, obviously enhance the bonding strength and compressive strength, and is good in construction performance and suitable for popularization and application.
一种湿拌砂浆外加剂，包括以下重量百分比的组分组成：减水剂：1‑5％，保水剂：0.1‑1.0％，保塑时间调节剂：5‑15％，引气剂：1‑4％，粘度调节剂：0.1‑0.3％，余量为水。本发明湿拌砂浆外加剂通过合理配置各原料组分，所得到的外加剂可以有效的增加砂浆的施工性、耐久性、增加砂浆的保塑时间至12‑48h、改善抹灰砂浆容易出现的空鼓、开裂等问题，同时可有效提高砂浆的保水率，并使粘结强度和抗压强度明显增强，施工性能好，适用于推广应用。
