The objective of this work is the study of recoverability of materials. It consists in studying the effectiveness of the addition of natural pozzolan on the thermal properties of the mortar. To do this, measuring instruments were installed to quantify the overall indoor environment and in particular the thermal environment. Given that the thermal environment is characterized by the physical quantities: the temperature of air, wall temperature and the air humidity. This allows gauging the level of the energy consumption and thermal behavior of the envelope of structure in order to verify the conformity of the housing to the requirements of thermal comfort. For this, we measured the thermal conductivity of mortars containing different contents of pozzolan (10%, 20%, 30%). So, the results showed the beneficial effect of pozzolan as thermal insulator by comparing with other insulation materials.

Interval arithmetic is an elegant tool for practical work with inequalities, approximate numbers, error bounds, and more generally with certain convex and bounded sets. In this section we give a number of simple examples showing where intervals and ranges of functions over intervals arise naturally. Interval mathematics is a generalization in which interval numbers replace real numbers, interval arithmetic replaces real arithmetic, and interval analysis replaces real analysis. Interval is limited by two bounds: lower bound and upper bound. The present paper introduces some of the basic notions and techniques from interval analysis needed in the sequel for presenting various uses of interval analysis in electric circuit theory and its applications. In this article we address the representation of uncertain and imprecise information, the interval arithmetic and its application to electrical circuits.
