Análisis comparativo de las propiedades físicas de aluminosilicatos en relación con el cemento puzolánico tipo IP

Abstract

The present investigation was initiated with the acquisition of natural zeolite in rock and sprayed in different deposits, for this investigation the classification of zeolite was determined according to ASTM C 618, the material used is a natural puzolana. Subsequently, manual and mechanical crushing of this mineral was continued until the desired fineness was obtained; The tests necessary for the characterization of the physical properties of IP-type cement and natural zeolite were then carried out, and the determination of the actual density of cement and zeolite was started as indicated in ASTM C 188 - NTE INEN 156. The test was then carried out to determine the fineness of these materials by dry sieving using the 150 microns sieve (No. 100) following the procedure of NTE INEN 489. To perform the chemical analysis Electronic Scanning Microscopy and X-ray scattering spectroscopy (SEM, EDS) of IP-type cement and natural zeolite, powder samples were taken from each material, This allows me to determine its morphology and components at an energy of 15 kilo electron boy (keV) with a level in detail of 2000 increases and in high vacuum mode (HV). The results obtained from the physical and chemical properties show the feasibility of this mineral (aluminosilicates) as a material with interesting cementing characteristics to partially replace cement.
