Abstract: Conventional concrete is the second most used product in the world, second only to water, taking this as a major component in their production cement. In short, one of the world’s largest consumer products used in the composition of the agents responsible for air pollution, this because during the cement manufacturing process are emitted tons of CO2 in the air. According to surveys conducted by regulators that value reaches 5% of the world’s CO2 emissions, in addition, promotes soil degradation due to the extraction of raw material (clay, limestone and gypsum) in addition to causing harmful effects on human health and the environment by the release of particulate matter. Within this context, this research aims to develop a chemical binder, called eco-cement, to replace partial and / or full forms the conventional cement in cement mortar, coating and reinforcement, thus minimizing pollution levels caused by the cement industry . For the binder composition in study used four materials: microsilica, nanossílica, sodium silicate and lime, which combined in predefined ratios and analyzed by quantitative and qualitative means gave rise to cementitious compounds necessary to ensure the strength of this. Thus, it prepared a folder with chemical binder, parallel to it, is concocted with other conventional cement, this used as a comparator with the binder in the study. From the best result it began the production of mortar being respected factor water / cement ratio, and standardized the molding procedure of the test bodies and healing methodology. The physical and mechanical properties of the final product was obtained from the dynamic modulus of elasticity tests and resistance to axial compression, proving its effectiveness in the application in brick laying and contributing effectively to the reduction of environmental impacts from their manufacture.
