Estudio de la correlación de las propiedades físicas y mecánicas de aluminosilicato de la cordillera Chongón-Colonche como sustituto parcial del cemento

Abstract

The cement industry is responsible for producing tons of carbon dioxide into the atmosphere and is one of the industries that generates the most pollution on the planet. Currently, supplementary cementitious materials (SCM) have been studied to help reduce this problem, one of them are aluminosilicates, better known as natural zeolites. In this work, data was compiled from previous works done by authors of the institution of characterization of physical properties such as density, fineness, specific surface and also morphological and chemical properties such as microscopy, determination of elements and oxides present in GU and IP cement, and some samples of the Chongón-Colonche mountain range aluminosilicates which are ZA, ZZ, ZI, ZV, ZX, ZCr, ZC, ZR and ZCa. Data was also collected at 7, 14, 28 and 56 days and mechanical properties such as compressive strength, indirect tensile strength and water penetration under pressure of concrete specimens with partial substitution of ZZ aluminosilicate in percentages of 10, 15 and 20 per cent were tested at 267 days, for the preparation of dynamic tables and graphs that serve us for a better analysis of the properties. The best aluminosilicate ZZ partial substitution is 15 per cent for concretes that don't require high strengths because at 28 days the compressive strength reaches 18.6 MPa and for concretes that need impermeability because at more aluminosilicate substitution the depth of water penetration decreases, at more time lapse mechanical properties are better.
