چکیده
Due to routine maintenance of aircraft on the concrete pavement at army airbases, a large part surface is often found saturated with different hydrocarbon-based oil, fuel, and fluid. In addition, subjected aircraft’s exhaust temperature during operation. This study examined resistance ability 3 cementitious materials: (i) epoxy, (ii) fly ash (FA) based geopolymer various alkali (AL/FA) ratios (iii) Portland cement (PC) mortar under simulated airfield circumstance. The specimens were repetitively exposed mixture synthetic engine hydraulic fluids, jet fuel elevated temperatures (175 °C) for 5 months simultaneously. During exposures, PC both suffered saponification. degree saponification samples be highly reliant AL/FA ratios. On contrary, epoxy was resistant It also that developed numerous thermal cracks but did not experience any visual same conditions.

Taftan Pozzolan-Based Geopolymer Cement
Abstract: In recent years, many research works have been done to investigate the possibility of utilizing a broad range of materials as raw materials in the production of geopolymer cements. The use of artificial pozzolans or aluminosilicate-type industrial waste materials such as granulated blast-furnace slag and fly ash has been reported in many research works. Natural pozzolans are also al...
متن کاملMechanical and Microstructural Evaluations of Lightweight Aggregate Geopolymer Concrete before and after Exposed to Elevated Temperatures
This paper presents the mechanical and microstructural characteristics of a lightweight aggregate geopolymer concrete (LWAGC) synthesized by the alkali-activation of a fly ash source (FA) before and after being exposed to elevated temperatures, ranging from 100 to 800 °C. The results show that the LWAGC unexposed to the elevated temperatures possesses a good strength-to-weight ratio compared wi...
متن کاملFly Ash-Based Geopolymer Mortar Incorporating Bottom Ash
This paper presents the results of study on effect of various parameters on mechanical properties of fly ash-based geopolymer mortar with bottom ash as partial or full replacement for sand. Compressive strength of samples with 10% bottom ash (BA) was comparable to those with only sand. Further increase in bottom ash content decreased the compressive strength. However, the reverse tendency occur...
متن کاملRheology of Geopolymer: Comparative Study between Portland Cement and Metakaolin Based Geopolymer
Metakaolin based geopolymers are presented in many studies as an alternative to normal Portland cement. Previous studies have focused on their chemical and mechanical properties, their microstructures and their potential uses, but very few on their rheological behaviour. Our work highlights the main differences that exist between geopolymer and Portland cement. These materials behave as Newtoni...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
