Análisis del comportamiento de ladrillos mediante elementos finitos

Abstract

Abstract: Blocks and fired bricks occupy approximately 95.57% of the elements most used in construction industry, being of main attention the evaluation of their mechanical resistance characteristics. Likewise, the different applications of these elements create the need of the study different sections of brick. Therefore, the analysis of different sections and mixtures of fired bricks and environmentally- cured bricks based on soil-cement materials by applying finite elements have been provided. The obtained results show the optimal section is a solid brick made of soil - cement and the addition of mineral plaster achieved a simple compressive resistance of 6.91 MPa exceeding by 38.26% the minimum resistance of 5 MPa established by the UNE 41410 standard for a block BTC 5 and a flexion of 1.36 MPa exceeding by 36% the resistance of 1 MPa recommended by Auroville Earth Institute for Class A blocks. Additionally, CFD analysis was carried out from the different brick sections and mixtures determining that soil - cement mixtures with the addition of mineral plaster reached an average absorption of 64.07%.
