Análisis físico y mecánico del ladrillo macizo "Tolete Común" producido en los chircales aledaños la ciudad de Tunja.

Abstract

The present Project of investigation is being carried out in order to analyse the physical and mechanical properties of solid brick of the surrounding chircales to the city of Tunja and show the results obtained as a methodological basis the Colombian technological standard NTC 4205 “units of masonry fired clay, bricks an ceramic blocks” and NTC 4017 “method for sampling and testing of masonry units and another clay products”. The main objective of these essays are to determine the compressive strength of the masonry units resulting in the maximum and minimum values. Likewise the estimation of the water absorption rate will be done, which would create some conditions at the time of sticking the units with mortar as it can affect masonry units beyond the minimum limits of permeability with absorption causing losses of humidity in the mortar causing cracking and low traction between the units and the mortar. The project will seek to give a diagnostic of the quality of materials that are traduced in brick factories located in the village of Pirgua near the city of Tunja, making a comparative table to each one of the qualities and defects that present the analysed unit of each brick pactory. In the development of the laboratories of initial absorption rate, compressive strength, immersion for 24 hours and rupture modulus, results were obtained that when compared with the Colombian technical standard, a large percentage of the brickwork is below the requirements Minimum required by it.
