Abstract
The objective of this paper is to study some characteristics of a component to buildings made with gypsum plaster (commercial - CGP and recycled - RGP), and wastes (red ceramic - RC and porcelain - PW) by loading-pressure. Bricks were prepared with a solid mass composition containing 50% (by weight) of binder, 50% (by weight) of waste, and very small water/dried powder ratio (0.22). Specimens were molded with uniaxial loading-pressure (10â¯kN) before setting times. Compressive and flexural strengths, porosity, and microstructure were evaluated. The compressive results were in the range of 12.3 and 33.9â¯MPa, higher than the minimum required by Brazilian Standards to building components (â¥2.5â¯MPa). The low water/solid mass ratio and the uniaxial loading-pressure before setting times contribute to decreasing the porosity, which was shown in the dense microstructure. The obtained results show that these components present a good quality building component.
