Addition of Grog-Clay Ceramic Waste in Multiple Use Mortar

Abstract

The clay ceramic industry for civil construction is responsible for the fabrication of common red products such as bricks, roofing tiles and structural blocks. A significant amount of waste from broken or distorted pieces is generated during industrial processing. Campos dos Goytacazes, in the north of state of Rio de Janeiro, Brazil, is one of the country’s largest producer of clay ceramics but does not have an appropriate destination for their waste, also called grog. The present work characterizes this grog as a possible addition into a multiple use mortar. The characterization parameters and properties analyzed according to the Brazilian norms for the grog and for the added mortars were the standard consistency index, incorporated air content, water retention and the resistance to compression. The results showed sensible variation in the parameters with the grog firing temperature. The mortars mechanical performance was satisfactory for its multiple uses with the advantage that the grog addition reduces the mortar production cost.

Description and effective parameters determination of the production process of fine-grained artificial stone from waste silica

“…Whereas, high porosity and microstructural defects in natural ornamental stones lead to contamination and brittleness, since outside fluids can penetrate to natural stone through pores and propagate cracks. Despite abovementioned positive points of artificial stones, it should be noted that some of them are not resistant enough in high traffic areas, as the materials are vulnerable to abrasion [11,30,31].…”

Evaluation of a Tacking Stage for Adherence, between Mortar and Ceramic Brick

“…The civil construction in Brazil is known by the large amount of waste materials generated in the several constructive stages [1]. The accumulated wastes in the working ground are estimated to be around 30% of the supplied raw material.…”
