Physicochemical characterization of cement treated kaolin clay

U ovom radu je predstavljena fizikalno-kemijska karakterizacija smeđe kaolinske gline s dodatkom cementa. Istražuje se utjecaj cementa na čvrstoću i stišljivost glinenih uzoraka uz variranje vremena njege i količine cementa. Na glinenim uzorcima s dodatkom 5 i 10 posto cementa obavljena su laboratorijska ispitivanja zbijenosti, jednoosne tlačne čvrstoće i jednodimenzionalne konsolidacije pomoću edometra. Rezultati ispitivanja čvrstoće i stišljivosti, provedenih tijekom dužega razdoblja, upućuju na porast jednoosne tlačne čvrstoće te na smanjenje indeksa stišljivosti.The physicochemical characterization of the cement-treated brown kaolin clay is presented in this paper. The effect of cement on the strength and compressibility of clay samples, at different curing times and cement contents, is investigated. Laboratory tests including compaction, unconfined compressive strength, and one-dimensional consolidation oedometer tests, were carried out on clay samples mixed with 5 % and 10 % of cement. Long-term strength and compressibility test results point to an increase in the unconfined compressive strength and decrease in the compression index
