Inovação orientada à sustentabilidade: desenvolvimento de um protótipo de argamassa estabilizada modificada para revestimento em paredes de alvenaria

Abstract

This research discusses the laboratory production of a modified stabilized mortar with the addition of acrylic copolymers that promote an increase of the adhesion of the mixture when applied on masonry of ceramic blocks. From the development of laboratory tests it was possible to verify that this product has several technical advantages, when countering the results obtained in the analysis of the fresh and hardened state with the commercially avaible stabilized mortar. Among the main advantages of the use of this "prototype" is the possibilitu of application as a coating without the execution of the roughcast, without prejudice to the mechanical tensile strength. In this way, it is noticeable that the prototype can be an innovation opportunity to be disseminated in the construction market. To do so, this study presented the creation of the laboratory prototype as a process of innovation, addressing the steps of survey, selection, definition of resources, implementation and learning. It is known that an apportunity for innovation should not be addressed only in the technical and economic aspects. Many other spheres should be analyzed so that it is possible to verify the idea as successful innovation. There are methods and tools that help in the classification of innovations focused on sustainability. In this way, an evaluation of the mortar prototype developed at the laboratory level was carried out, classifying its innovation potencial analysed through a two-dimensional slice of the innovation cube model, leaving aside the dimension of the types of innovation.Thus, through the analysis tools presented by Hansel et.al. (2009) discussed the social, environmental and economic effects of the prototype at laboratory level throughout its life cycle. The existence of social, economic and environmental benefits in the use and application of the prototype is noticed, mainly due to the reduction of a constructive stage in the execution of mortar covertings in masonry walls, which makes it attractive to implement an economic feasibility study on the production and commercialization of this product, which may be an incremental innovation of the mortar commonly marketed by concrete and mortar industries.
