Study of the Feasibility of Incorporation Clay from Campos Dos Goytacazes-RJ, in Mortar Applied on Walls and Ceilings

Civil construction is in constant search for alternatives to reduce the degradation of the environment and, therefore, studies new materials technologies that are sustainable. Mortar is an example whose raw materials involve a high commercial value and highly energetic production processes in relation to CO2 emissions. This work compares embedded clay mortars for use in wall and ceiling coverings. These are two clays: a clay from Campos dos Goytacazes-RJ and an industrialized clay collected from local businesses. For this purpose, characterization of the aggregates, study of the mortar dosage, consistency indexes, water retention tests, specific gravity, compressive strength, and tensile bond strength were carried out. The results indicated that Campos clay tested as a material for dosing mortar in wall and ceiling was compatible with industrial clay, allowing the commercialization of the studied product.
