【摘要】：研究了不同堿度的氫氧化鈣(CH)溶液和氫氧化鈉(NH)溶液對(duì)脫硫建筑石膏凝結(jié)時(shí)間、2 h強(qiáng)度的影響,并通過(guò)水化溫升、XRD和SEM技術(shù)探索了其影響機(jī)理。結(jié)果表明:在拌合水p H值為7.6~12.0內(nèi),隨著堿度的提高,脫硫建筑石膏的初凝、終凝時(shí)間都明顯縮短;在p H值為9.0左右時(shí),2種水化環(huán)境中脫硫建筑石膏的抗折、抗壓強(qiáng)度性能都最佳;堿性環(huán)境還改變了二水石膏的結(jié)晶相變熱、結(jié)晶化程度、結(jié)晶形態(tài)和密實(shí)程度。
[Abstract]:The effects of different alkalinity of calcium hydroxide (CH) solution and sodium hydroxide (NH) solution on the setting time and 2 h strength of desulphurization building gypsum were studied, and the mechanism of the effect was explored by hydration temperature rise, XRD and SEM technology. The results show that when the pH value of mixed water is 7.6 鈮，
