AVALIAÇÃO DE DESEMPENHO DE PAVERS INTERTRAVADO PRODUZIDOS COM REJEITOS GERADOS NOS DESDOBRAMENTOS DE ROCHAS ORNAMENTAIS

Abstract

ABSTRACT: The aim of this paper was to study the compressive strength of pavers produced with tailings generated in the development of ornamental rocks. Several strokes with different percentages were elaborated and part of the stone dust was replaced by abrasive mud. Studies have shown that the addition of abrasive sludge in the making of the blocks has shown a satisfactory result, increasing the compressive strength, the Standard strokes, 1 and fit the Australian and African Standards, while the Trace 3 and Trace 4 reached beyond Australian and African Standards also the Brazilian Standard, which requires at least 35MPa for pedestrian, light vehicle and commercial line traffic.
