發(fā)布時間：2018-10-23 17:22
【摘要】：對比了礦渣對阿利特-硫鋁酸鹽水泥(AC$AC)和普通硅酸鹽水泥(OPC)強度的影響,結(jié)合水化熱、X線衍射(XRD)圖譜和掃描電子顯微鏡(SEM)研究不同混合水泥的水化。結(jié)果表明:文中制備的阿利特-硫鋁酸鈣水泥對礦渣有較好的復合性。礦渣的摻入會降低水泥的1和3 d強度,對28 d強度影響不大。阿利特-硫鋁酸鈣水泥復合10%的礦渣能達到最好的性能(1、3和28 d強度分別為16.94、34.47和51.54 MPa)。其中1和3 d強度比同礦渣摻量的空白樣和普通硅酸鹽水泥樣品高,甚至高于未摻礦渣的兩種水泥的強度。礦渣的摻入會增加含硫鋁酸鹽礦物水泥樣品的膨脹率。礦渣含量增加,加快三硫型水化硫鋁酸鈣(AFt)向單硫型水化硫鋁酸鈣(AFm)的轉(zhuǎn)變。
[Abstract]:The effects of slag on the strength of alite-sulphoaluminate cement (AC$AC) and Portland cement (OPC) were compared. The hydration of different mixed cement was studied by combining hydration heat, X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that the Allite-calcium sulphoaluminate cement prepared in this paper has good compounding property to slag. The addition of slag reduced the strength of cement in 1 and 3 days, but had little effect on the strength of 28 days. The slag with 10% Allite-calcium sulphoaluminate cement can achieve the best performance (1C _ 3 and 28 d strength are 16.94 ~ 34.47 and 51.54 MPa)., respectively). The strength of one and three days is higher than that of blank sample with the same amount of slag and ordinary Portland cement, and even higher than that of the two kinds of cement without slag. The addition of slag will increase the expansion rate of sulphoaluminate mineral cement samples. The increase of slag content accelerates the transition from (AFt) to (AFm).
