松香酸钠复合外加剂是一种砂浆的新型外加剂。它的材料来源广泛,易于配制,使用方便,在实际工程中的应用已充分显示了它的优越性和技术经济效果。这种复合剂,比苏联生产应用的“木柏油”砂浆外加剂优越。“木柏油”砂浆外加剂,在混合砂浆中,只能节约生石灰1/3～2/3,并不能提高砂浆强度,同时不适用于抹 The sodium rosinate compound admixture is a new admixture for mortar. It has a wide range of sources of materials, is easy to formulate, and is easy to use. Its application in practical engineering has fully demonstrated its superiority and technical and economic effects. This compounding agent is superior to the Soviet Union’s production and application of “wood asphalt” mortar admixtures. The “asphalt oil” mortar additive, in the mixed mortar, can only save 1/3 to 2/3 of the lime, and it can’t increase the strength of the mortar. It also does not apply to the wipe.
