Argamassa autonivelante : análise econômica-financeira do seu uso em contrapisos

Abstract

The use of self-leveling mortar in the execution of subflooring is an execution method recently adopted in Brazil, which has been gaining market share due to its speed of execution, optimization of the construction site and good surface finish. The main function of this material is to fill empty spaces and to self-compact only under the effect of gravity and its own flow capacity, without segregation of the aggregates and with leveling. Due to its fluid composition, the self-leveling mortar allows it to be pumped directly to the application site, avoiding losses. There is an absence of standards regarding the material and its method of execution in Brazil, and an absence of an economic-financial feasibility study of its use, making it necessary to systematize the data and characteristics relevant to the subfloor made with self-leveling mortar, to provide necessary information. To designers and builders in the development of projects and execution of works. This work aims to study the properties and characteristics of the subfloor made with traditional mortar, a method popularly known as “farofa”, and with self-leveling mortar, with a focus on the financial viability of the execution of the subfloor with self-leveling mortar.
