Ternary diagrams SiO₂-Al₂O₃-K₂O as tool for the analysis of ceramic materials behavior

Abstract

The present study about ternary diagrams of SiO2-Al2O3-K2O has been conducted from the determination of two possible optimal clay mixtures through hydrometric tests of a company dedicated to the manufacture of masonry products for construction in the North region of Santander in Colombia; this work is the continuation of others carried out previously. In this raw material (clay) the dominant minerals are silica, alumina, iron, potassium, among others, which provide the plasticity and adequate granulometric distribution. Two optimal m7 and m8 mixtures were selected from 5 samples (M1, M2, M3, M4 and M5) of clays from different points of the company’s mine, these mixtures were analyzed by Fluorescence and X-ray diffraction tests with the purpose of determining the chemical elements in their maximum percentage and to be able to graph them in ternary diagrams with the help of FACTSAGE software and finally determine their cooking behavior. The results of the investigation showed that the physical characterization of the clays provides a broad view on the technological behavior of the raw material and consequently the quality of the final product.

Physical-Mechanical properties of H-10 blocks manufactured in Norte of Santander, Colombia: a case study

“…Also, is evident that the raw materials of Cucuta Company have minor impurities than Ocaña Company [7,33]. In this way, clay aid to obtain an adequate plasticity index, the Al 2 O 3 contributes to the flux, and the SiO 2 as a stabilizer [34].…”

Determination of the physical-mechanical properties of a permeable block

“…The PET percentage was established at 10%, 15%, and 20% to substitute the total amount of sand established for the resistance required for non-structural masonry according to the NTC-4076 [21]. Likewise, the substitution was established to the procedure developed by NSR-10 [17], to calculate the initial proportions of the materials used in the mortar, without making adjustments by fluency the estimated calculations were for a 1:4.11 ratio [22].…”
