It is observed after the evacuated processing with metal spraying of 28d mortar specimen using Hitachi-3400N scanning electron microscope hard The microscopic appearance of slurrying body can be seen that alkaline residue-slag-cement ternary cementitious material system 28d hydration age by Fig. 2 a~2c Hydrated product it is abundant, hardened paste structure basically forms, and paste structure is finer and close, bonds relatively close between hydrated product, has A small amount of hole and crack exist.It is distributed in hydrated product surface in the crystal of needle bar shape and irregular sheet, while there are also a small amount of Unreacted gelling material particles are distributed in around hydrated product.
Material phase analysis is carried out to 28d net slurry sample using X-ray diffractometer.Cu target, tube voltage 200kV, tube current 40mA. The scanning range of 2 θ of the angle of diffraction is set as 10 ° to 80 °, and sweep speed is 1 °/min.It can be observed that occurring 3CaO in Fig. 3 Al2O3·CaCl2·10H2The apparent diffraction maximum of O.Just as shown in Figure 2 b, hydrated product surface is distributed in needle bar shape and is not advised Then the substance of sheet is exactly 3CaOAl2O3·CaCl2·10H2O crystal.CaCO has been observed in XRD spectrum3Diffraction maximum In the presence of, be due to sample sampling and test process in hydrated product Ca (OH)2It is carbonized.Although C-S-H belongs to amorphous State, and spectral line to be to diffuse based on peak, but map occurs apparent " convex closure " phenomenon at 25-35 °, illustrates alkaline residue-slag-cement There is the generation of C-S-H gel in the hydrated product of ternary cementitious material system 28d hydration age.
Thermogravimetric and differential thermal point are carried out to 28d net slurry sample using German NETZSCH company STA449F5 synthesis thermal analyzer Analysis, to prevent sample to be carbonized during heating, when test, use Ar for protective gas, and heating rate is 10 DEG C/min. From fig. 4, it can be seen that net slurry mainly occurs six endothermic peaks and two exothermic peaks in 28d hydration age.Wherein endothermic peak It is located at 106.9 DEG C, 186.4 DEG C, 299.3 DEG C, 334.2 DEG C, 467 DEG C and 609.9 DEG C.Exothermic peak is 717.6 DEG C and 904.9 DEG C present position.Endothermic peak positioned at 106.9 DEG C is due to 3CaOAl2O3·CaCl2·10H2O sloughs the generation of part water, Form 3CaOAl2O3·CaCl2·6H2O.Endothermic peak positioned at 299.3 DEG C is 3CaOAl2O3·CaCl2·6H2O continues Caused by sloughing 5 crystallizations water.It and is that the dehydration heat absorption of C-S-H gel is made positioned at 186.4 DEG C, 334.2 DEG C and 467 DEG C of endothermic peak At.Wave crest positioned at 609.9 DEG C be continue due to hydrated calcium chloroaluminate dehydration inhale it is thermogenetic.Positioned at 717.6 DEG C of positions Exothermic peak is then that further crystallization is produced due to hydrated calcium chloroaluminate.Occurring exothermic peak positioned at 862.2 DEG C is because corresponding Crystal transfer has occurred in C-S-H gel, is converted into β-wollastonite.By the analysis to DSC-TG curve, prove in system Hydrated product C-S-H gel and 3CaOAl2O3·CaCl2·10H2The presence of O crystal.
CaO chance water in alkaline residue, which reacts, generates Ca (OH)2, Ca (OH)2Presence make alkaline residue-slag-cement ternary glue The pH value of gel material system increases, while containing active SiO in slag2And Al2O3, they can be in alkaline environment Generate C-S-H gel and C-A-H gel.With deepening continuously for degree of hydration, the gel of generation is constantly assembled, to make entire System generates intensity.Meanwhile containing a large amount of chloride ion in alkaline residue, chloride ion can generate 3CaO with C-A-H gel reaction Al2O3·CaCl2·10H2O crystal.C-S-H gel and 3CaOAl2O3·CaCl2·10H2O crystal has collectively constituted entire body The primary intensity source of system.
Finally it should be noted that：Above-described embodiments are merely to illustrate the technical scheme, rather than to it Limitation；Although the present invention is described in detail referring to the foregoing embodiments, those skilled in the art should understand that： It can still modify to technical solution documented by previous embodiment, or to part of or all technical features into Row equivalent replacement；And these modifications or substitutions, it does not separate the essence of the corresponding technical solution various embodiments of the present invention technical side The range of case.
