砂浆中掺用微沫剂可以节约白灰,当水泥标号较高,砂浆强度较低,而又无条件掺用混合材时,为满足和易性要求,掺用微沫剂还可达到节约水泥的目的。掺用微沫剂可以取得较好的技术经济效果,又便于施工操作,宜于保证砌筑质量。为确保获得技术上质量稳定可靠,经济上效益更加显著的微沫剂,许多单位都自行制备。配制中需用的氢氧化钠(即烧碱)或碳酸钠(即纯碱)的量,决定于松香皂化值的大小。所谓松香皂
The use of micro-foam in mortar can save white ash. When the cement number is higher and the strength of mortar is lower, and when the admixture is unconditionally mixed, in order to meet the workability requirements, the use of micro-foam can save cement. . The use of micro-foams can achieve better technical and economical results, facilitate construction operations, and ensure the quality of masonry. In order to ensure that the technically stable and reliable quality and economic benefits are more pronounced, many units are self-produced. The amount of sodium hydroxide (ie caustic soda) or sodium carbonate (ie soda ash) required in the formulation depends on the saponification value of the rosin. Soap soap
