Argamassas de terra no estado endurecido: influência dos teores de cimento e argila

Abstract

Nowadays, humanity goes through several social and environmental problems related to the ecological imbalance. In this sense, there is a tendency to appreciation the ways of sustainable development, including the civil construction industry, which is responsible for most of the impacts generated by anthropic activities. Therefore, land appears as an alternative, being quite versatile and enabling the execution of projects at a reduced cost and with high energy efficiency, in addition to offering several technological advantages related to the internal comfort of environments. Thus, this work aims to study the soil stabilization technique that consists of adding Portland cement to the mixture, which allows an improvement in the performance of the final product in several aspects through the physical and chemical changes that occur with this interaction. For that, a bibliographic review was carried out with the exposition of several results, especially with regard to the variation in cement and clay contents, through which analyzes and discussions were made, verifying compatibility, possible inconsistencies and gaps in the studies presented. With this, it was verified that this stabilization technique constitutes an important mechanism to overcome the difficulties inherent to earth constructions, favoring the execution of more durable, sustainable and less expensive projects. As main results, it was observed that this technique improves the strength and durability of the product, in addition to contributing to the dimensional stabilization.
