摘要:
基于矿井复杂环境对封孔水泥提出的要求，引入２-丙烯酰胺基-２-甲基丙磺酸（AMPS）并复合聚羧酸减水剂，三乙醇胺（TEA）作为有机组分，氯化钠（氯化钙）为无机组分，模拟井下高湿环境，通过正交试验，考察了两种有机无机复合早强剂的制备。并通过SEM，TG和XRD等手段着重研究了两种复合早强剂水化3d对封孔水泥抗压强度的影响。结果表明，当氯化钠复合早强剂组分为氯化钠3%，三乙醇胺0.05%，聚羧酸0.3%，AMPS1%时；氯化钙复合早强剂组分为氯化钙1.5%，三乙醇胺0.04%，聚羧酸0.2%，AMPS1%时早强效果最好，抗压强度比基准组分别提高了328%和217%。
Abstract:
Based on the requirements of hole sealing cement under the complicated environment of coal mine, 2-Acrylamido-2-methyl-1-propanesulfonic acid (AMPS) with a combination of polycarboxylate superplasticizer and triethanolamine (TEA) was taken as the organic component, and sodium chloride (calcium chloride) was taken as the inorganic component under the simulated underground environment with high humidity. The orthogonal experiment was utilized to investigate the preparation of two kinds of organic and inorganic compound early strength agents. The influence of hydration 3d for two kinds of compound early strength agents on the compressive strength of hole sealing cement was studied with emphasis through the methods of scanning electron microscope (SEM), thermogravimetric analysis (TG) and X-ray diffraction (XRD). The results showed that the early strength performance was the best when the component of sodium chloride compound early strength agent was 3% sodium chloride, 0.05% TEA, 0.3% polycarboxylic acid and 1% AMPS, as well as when the component of calcium chloride compound early strength agent was 1.5% calcium chloride, 0.04% TEA, 0.2% polycarboxylic acid and 1% AMPS, with the compressive strength increasing by 328% and 217% respectively compared with the baseline group.
