| Abstract | This research was to determine the amorphous silica in perlitethat affected compressive strength and degree of pozzolanicreaction by using X-ray diffraction method. In this study, perlite was burnt at different temperaturesof 600?c, 700 ?c and 800?c and different timeof 4, 6 and 8 hr. Perlite and sand were ground to approximately the same finenessascement. Portland cement type1 was replaced by perlite or ground sand at 20% by weight of cementitiousmaterial. A water to binder ratio(w/c) of 0.40 was used. The result of X-ray diffraction showedthat the perlite burnedat 600?c for 4 hr. contained the largestamorphousesilica.From the compressive strength test and the pozzolanic activity testit was shownthat the amorphouse silica contents affected on compressive strength and degree of pozzolanic reaction |
