Abstract

Clay bricks are the most important engineering materials that can influence the quality of the construction. The quality control of the clay bricks is of prime importance to improve the quality of engineering construction. The qualities of bricks for construction applications should be checked for various types of inspection services. In this article, our inspection service was focused on compression strength test on bricks to determine their mechanical resistance and suitability for construction work. The accurate method for clay brick's production measurements has been elaborated using uniaxial compressive strength testing machine. The method was tested for a rectangular clay brick manufactured with size approximately 250 mm × 250 mm × 200 mm. The measurement method and standard uncertainty estimation of uniaxial compressive strength are briefly described in this article.

Summary

Introduction

Clay brick materials are the oldest building materials in the world and are still immensely popular [1]. Edilcentro Ltd. is one of the leading companies in Albania in the field of bricks’ production of high quality. In this company, the phases of clay bricks’ production are under automatic control and permanent supervision of the technological process [2]. One of the basic and most used methods of testing which is performed on brick samples is the determination of uniaxial compressive strength [3]. According to the American Society for Testing and Materials (ASTM) specifications, we have performed compression testing for the determination of the properties of clay brick materials. We have briefly described the measurement method and standard uncertainty estimation of. Measured uniaxial compressive strength which would 3 Uncertainty of uniaxial compressive depend on the force applied to the sample
