Influence of heat treatment on the mechanical properties of alkali-activated fly ash-based binders with marble dust substitution

چکیده
Abstract Marble waste contains a high level of calcium, which is obtained from the cutting process in marble production. The properties geopolymer binders are influenced not only by amount alkali activators, their ratio, molarity used, and Si Al content mineral additives used mixture, but also duration heat treatment temperature. This study aimed to produce alkali-activated based on fly ash dust. Alkali-activated pastes were made both with for 24h at 70°C without (23±2) °C. Structural analysis optical microscopy revealed, case heat-treated samples, formation pores an average size 1÷1.5 mm, much larger than samples treatment.

متن کاملMicrostructural Characteristics of Geopolymers Based on Alkali-Activated Fly Ash
Aluminosilicate geopolymers with a high silica molar ratio have been prepared by mixing Croatian coal-ash (ASTM Class F) and sodium silicate solution (water glass, technical grade). The samples were cured at 85 °C for 8 h and 24 h in different experimental conditions. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM/EDS) have been use...
متن کاملStudy on the Alkali Activated Fly Ash Mortar
The development of alkali-activated binders seems to present a greener alternative to OPC. The present study has been made on the low calcium fly ash with alkali activator as an alternative binding material as mortar. The mortar has been prepared with ennore sand and Indian fly ash mixed with alkali activator fluid consisting of sodium silicate and sodium hydroxide of different concentrations. ...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
