• Abstract:

  Given the whole research results presented at International Congresses such as IX SBTA 2011 at Belo Horizonte, Brazil, 1st I+I+D Fair 2015, F.I.U.N.A. held at San Lorenzo, Paraguay, IV ALCONPAT 2016, at Asunción and VII CONIMAT 2016 at Cusco, Peru, and the interest for these subjects, we continue researching on solid ceramic bricks quality jointed with mortars to form walls. As the former research established that bricks contribute in a larger way in its elastic and rigidity modules than the mortar, and that the final contribution is superior to those of the mortar, showing synergy between mortar and bricks in final bending and compression strength, these is shown in this paper by graphs and number after making more than 360 (880 more precisely) essays of these materials which makes walls. In this research we study not only the physical properties, but also analyze the chemical properties with traditional technologies and with EDX. The correlation between the raw materials physic and chemical properties and its compression and bending strength, brings up the importance to know these properties in raw materials in order to design and produce more efficient materials and with better performance. We combine two different raw materials from different soils in Paraguay to produce bricks in laboratory and study 20 different bricks offered in Asunción, selected in categories, to correlate its initial and final chemical and mechanical properties. Also other mechanical and physics properties are affected by chemical composition. The bricks have been categorized A, B, C and N/C (not categorized) according to Paraguayan Standard NP 17 027 77 second edition of 2015, Specifications for solid ceramic bricks, and this research will help us to know how to design better bricks using laboratory equipment such as sieves, weighing scales, X Ray Energy Disperser, compression machine, micrometer, oven, electronic devices, and other to use appropriate materials or combining them to produce well categorized bricks using local technology towards getting better.
