Thermal and Physico-Mechanical Characterization of Paraíba’s State Soils to Applying in Soil-Cement Bricks

Abstract

Soils play a decisive role in the manufacture of building materials, especially, tiles and bricks. Production techniques cause negative impacts on the environment and add additional time to the production process. Three samples obtained from Paraíba State were characterized by thermal characterization, granulometric and physical-mechanical techniques. Thermal analysis was undertaken in two different atmospheres, at a flow rate of 110 ml/min and a heating rate of 10oC/min. Evaluation of the soils through their thermal characteristics for use in soil-cement bricks production is elucidated.

Reuse of Waste Water-Based Paint

“…Chemical analysis from soil shows it is predominantly constituted by SiO 2 , Al 2 O 3 and TiO 2 (table 2). This mixture is adequate to soil-cement bricks [4]. 1 it is noted that the resistance increases with the increasing amount of waste paint to the incorporated residue.…”
