本研究旨在探討添加卜作嵐摻料對水泥漿體水化特性之影響。首先，在改變水膠（灰）比、卜作嵐摻料取代水泥百分比及試驗齡期的條件下，針對三種系列漿體（即純水泥漿體（Ordinary Portland Cement Paste，簡稱OPC漿體）、飛灰-水泥漿體（Fly Ash-Cement Paste，簡稱FC漿體）以及爐石-水泥漿體（Slag-Cement Paste，簡稱SC漿體）），進行抗壓強度試驗、燒失量分析及MIP孔隙試驗。其次，探析試驗參數對各系列漿體抗壓強度、非蒸發水含量、Ca(OH)2含量、卜作嵐摻料反應程度、漿體孔隙之影響，並探討各種變因間的相互關係。最後，則分析與討論各項試驗結果間之關聯性，進而藉由所獲致的試驗數據建構其關係式。
研究結果顯示，隨著水膠比之增加，各系列水泥漿體的非蒸發水含量、CH含量、卜作嵐摻料反應、水泥水化程度及總孔隙量亦增加，但漿體的抗壓強度及膠體/空間比則降低；卜作嵐-水泥漿體的非蒸發水含量會隨著卜作嵐摻料取代水泥百分比之增加而減小；隨著齡期及水灰比的增加，OPC漿體的CH含量亦增加，而28天後的增長趨勢已逐漸平緩，FC與SC漿體的CH含量則是隨著卜作嵐摻料取代率及齡期的增加而減少；卜作嵐摻料的反應程度與漿體齡期及水膠比有關，在相同水膠比條件下，爐石的反應程度大於飛灰者；漿體孔隙量隨卜作嵐摻料取代率增加而增加，在低水膠比及低取代率條件下，卜作嵐摻料對漿體有較佳的填充性；膠體/空間比隨著卜作嵐摻料取代率的增加而降低，不論是FC漿體或SC漿體，在最大取代率時，其膠體/空間比降低幅度都遠較其他取代率者為大；在總孔隙量與抗壓強度及總孔隙量與膠體/空間比之相關性上，OPC漿體之相關係數最佳（其R2分別為0.9242及0.8845）。

The purpose of this research is to investigate the effects of adding pozzolanic materials on the hydration characteristics of the cement paste. First, for the conditions of varied experimental parameters including water-to-binder ratios(w/b), pozzolanic material replacements and testing ages, the compressive strength tests, the ignited loss analysis, and the MIP porosity measurements were conducted on three series of pastes— ordinary Portland cement (OPC) paste, fly ash-cement (FC) paste and slag-cement (SC) Paste. Second, the effects of experimental variables on compressive strength, non-evaporable water (wn) content, Ca(OH)2 content, degree of pozzolanic reaction and porosity of the three series of pastes were studied. The interaction existing in these variables was also assessed. Finally, the correlations between the results of each test would be analyzed and canvassed. The correlation formula would be further established according to the obtained experiment data.
Test results show that, for all series of pastes, with w/b increasing, wn content, Ca(OH)2 content, degree of pozzolanic reaction, degree of cement reaction, and porosity would increase. However, the compressive strength and the gel/space ratio of the pastes would decrease; For pozzolan-cement pastes, the wn content would decrease with the increase of the percentage of cement replaced by pozzolanic material; For OPC pastes, with the increase of age and w/b, the Ca(OH)2 content would increase, but after 28 days, the raising tendency has gradually slowed down. Nevertheless, the Ca(OH)2 content of FC and SC pastes would decrease with the age and the proportion of replacement increasing; The reaction degree of pozzolanic material is in connection with age and w/b. For the same w/b, the reaction degree of slag (14.7~40.3%) is higher than that of fly ash (3.1~28.3%); The porosity of paste would increase with the increase of pozzolanic material replacement. For lower w/b and replacement level, pozzolanic materials would have the better capability of filling pores; The gel/space ratio would decrease with the increase of the replacement of pozzolanic material. For both FC pastes and SC pastes, at the highest replacement level, the reduced extent of gel/space ratio would be significantly higher than that at the other replacement levels; As for the correlations between total pore volume and either compressive strength or gel/space ratio, OPC pastes possess the optimum correlation coefficients (R2 = 0.9242 & 0.8845).
