Estudo comparativo entre elementos construtivos de vedação em painéis pré-moldados de concreto e drywall em um galpão comercial

Abstract

Civil construction is in constant evolution, always looking for solutions that provide cost reduction, speed in execution, less material waste and promote sustainability. Considering this scenario with regard to constructive elements of sealing, two types widely used in the labor market deserve to be highlighted: precast concrete panels and drywall. Each system has its own characteristics, for example, the use of precast concrete provides the optimized use of materials, with little waste, the material is fire resistant and not harmful to the environment. Drywall, on the other hand, allows for greater use of useful area, load relief in foundations, it is a material that can be recyclable, among others. Thus, this work presents a comparative study between these two constructive elements of sealing, demonstrating the advantages and disadvantages of both methods, assembly, transport, execution time, waste of inputs, volume of debris, damage to the environment. For this purpose, a concrete case of a shed with an area of 562.74 m2 for Drywall and 571.2 m2 for Precast concrete is used, different areas due to the execution methods adopted. In the work, data, budgets and results are used to conclude which method is more viable.
