A New Study on the Eastern Flank of the Loma Blanca Deposit (Cuba) to Establish the Mineralogical, Chemical, and Pozzolanic Properties of Zeolitised Tuffs

The geological nature of the territory Republic Cuba has favoured formation large and varied deposits volcanic tuffs enriched by various species zeolites. Today, new zeolite continue to be discovered in country. This work aims present results a study carried out an unexplored area that is located approximately 1.2 km east Loma Blanca deposit, outside mining operation limits. To carry this research establish qualitative comparison between both sample populations, four samples were taken from area, another deposit. characterisation was performed XRD, SEM, XRF. pozzolan quality determined pozzolanicity test (PT) chemical analysis (QCA). Finally, mechanical strength (MST) at 7, 28, 90 days, using mortar specimens made with PC/ZT: 75–25% 70–30%, respectively. studies XRF indicated groups had similar complex mineralogical composition, consisting mainly mordenite clinoptilolite accompanied secondary phases such as quartz amorphous materials form altered glass. showed those deposit behaved like typical pozzolans, which trend can seen high values compression up 72 MPa for formulation 66 70–30%. obtained varieties detected are could have positive impact on increase current reserves, especially manufacturing pozzolanic cements properties contribute preservation environment.
