Foam concrete, additive thereof and additive adding method
The invention relates to the technical field of building materials, and provides foam concrete, an additive thereof and an additive adding method. The admixture is composed of a component A and a component B. The component A is composed of, by mass, 130-160 parts of sulfonated acetone formaldehyde condensate, 40-60 parts of lignosulfonate, 80-120 parts of calcium formate, 8-25 parts of hydroxypropyl starch ether or soluble starch and 4-8 parts of sodium sulfate. The component B is prepared from 30 to 60 parts of triethanolamine or triisopropanolamine and 18 to 25 parts of hydroxypropyl methyl cellulose. The admixture is designed for coal cinder, has an alkali excitation function, enables the coal cinder to react, can replace part of cement, can comprehensively replace fly ash and reduces the material cost, the invention further provides an addition method of the admixture, the admixture is added in two procedures, and the cost is reduced. And it is guaranteed that the minimum amount of the admixture plays the best role.
本发明涉及建筑材料的技术领域，提供一种泡沫混凝土及其外加剂及外加剂添加方法。本发明的外加剂由A组分和B组分组成，按质量份数计，所述A组分由磺化丙酮甲醛缩合物130‑160份、木质素磺酸盐40‑60份、甲酸钙80‑120份、羟丙基淀粉醚或可溶性淀粉8‑25份、硫酸钠4‑8份组成，所述B组分由三乙醇胺或三异丙醇胺30‑60份、羟丙基甲基纤维素18‑25份组成。本发明的外加剂针对煤渣而设计，具有碱激发的功能，使煤渣自身反应，可替代部分水泥的用量，本发明的外加剂可以全面代替粉煤灰，降低了材料成本，本发明还提供一种外加剂的添加方法，分两个工序添加，保障外加剂用最少的量发挥最好的作用。
