By studying alkaline-activated complex systems with coal gangue calcined at 750°C and slag, the results can show that under action of soluble glass, when weight fraction was less than 30%, mechanical strength composite may be more 40 MPa. But is higher 60%, decreased faster alkali-activated slag cementitious materials. X-ray diffraction (XRD) method determination chemically combined water content were used to study hydration course The major product zeolite change consistent development.
Through determining Ca(OH) 2 content and chemically combined water content, hydration degree of cement with added-calcium thermal activated coal gangue may be analyzed. Variation mineral composition during process system was analyzed by X-ray diffraction(XRD) method. Simultaneously, specific strength index applied to study pozzolanic effect gangue. The results can show high contribution calcined at 1050°C for properties reaction in this kind activared system, fewer more obviously reduced...
Activation of coal gangue from Yixing was done by the method addition calcium during calcination. Structural characteristic and cementitious properties activated samples were analyzed. And then hydration degree cement studied. The results show that: thermally chemically added-calcium composite activation can improve activity gangue. At 1050°C, more effective silicate minerals may be in samples, with which system have a higher hydration. infra-red(IR) spectra shows that large number new...
Three kinds of complex chemical activators were prepared and then introduced into calcined coal gangue cement. Physical mechanical properties such as mortar fluidity strength shrinkage tested. The results can show that: excitation effects multiple may obvious, where with 8% J1, 50% cement replaced activated gangue, compressive the system at ages 28 days reach 40.7MPa. Compared without exciting agent, in early increased obviously later be equivalent to that pure
