Method for producing lightweight concrete from ardealite raw slag
The invention discloses a method for producing lightweight concrete from ardealite raw slag, which does not need gravels, uses ardealite raw slag as a main material, and comprises the following raw materials by mass: 70-90 parts of ardealite raw slag, 5 parts of a modifier, 4 parts of an adhesive, and 1 part of a foaming agent. The production method comprises the following production steps: S1, adding ardealite raw slag into a stirring tank at an ardealite raw slag outlet of a phosphoric acid or phosphate fertilizer production line, and adding the modifier of ardealite to obtain a mixed slurry; S2, adding the adhesive into the mixed slurry, stirring, and pouring; S3, adding the foaming agent into the pouring material after pouring is completed, and nursing and hardening; S4, cutting the cured and hardened castable into building blocks, feeding the building blocks into a heat preservation room for heat preservation, moisture preservation and curing, and finally moving the building blocks into a natural drying and dewatering area for storage; under the condition of not using gravel, the ardealite raw slag is used as a main material, so that the problem of acidic pollution in ardealite can be solved, and the lightweight concrete blocks reaching the standard can be produced.
本发明公开一种磷石膏原渣生产轻质混凝土的方法，不需要砂石，以磷石膏原渣为主材料，原料配方按质量计数如下：磷石膏原渣：70‑90份、改性剂5份、粘合剂4份、发泡剂1份；其生产步骤如下：S1、在磷酸或磷肥生产线的磷石膏原渣出口，将磷石膏原渣加入搅拌槽，加入磷石膏的改性剂，得混合料浆；S2、将混合料浆加入粘合剂搅拌后进行浇筑；S3、将浇筑完工后的浇筑料进行添加发泡剂，并进行护养硬化；S4、将养护硬化后的浇注料切割成砌块，送入保温房进行保温保湿养护，最后移入自然干燥脱水区维存；本发明能在不使用砂石的情况下，以磷石膏原渣为主材料，能解决磷石膏中的酸性污染问题，能生产达标的轻质混凝土切块。
