Abstract Significant self-glazed glass-ceramic was obtained from a natural pozzolan and external glass cullet. Natural with/without cullet fused to melt that quenched in water frits. The dried frits were pulverized (<0.083 mm) then shaped stainless mold. thermal behavior of the glasses shows widening crystallization temperature with incorporation between ∼800 950°C. Sintering powder at 1,050...

geopolymer cement (inorganic polymeric binder) based on natural pozzolan are investigated. SiOof activator and total molar ratios of Nacomposition exhibiting the highest 28-day compressive strength. Mixtures exhibiting the highest compressive strength were studied for their molecular structure using laboratory technique of Fourier transform infrared spectroscopy.Results obtained confirm that ch...

This paper presents the improvement of pozzolanic properties oil palm boiler ash (OPBA) through heat treatment. The OPBA was obtained from mill in Pahang, Malaysia. composition measured using X-ray fluorescence spectrometer which used for its initial classification. It found that freshly had high carbon content (33.9%) and cannot be classified as pozzolan with only 15.73% Al2O3, SiO2 Fe2O3. Upo...
