FINAL CONSIDERAES the analysis gotten they allow in it to affirm that effectively a type of block does not exist that is more efficient than another one, that has a series of factors that determine this definition. This goes to vary of region for region, qualification of the hand of used workmanship, tipologia of the construction, financial market and also through a good purchase. The financial aspect was very not taken in account due the enormous amount of companies of the branch, as well as the use of the mortar, that varies in the production of this insumo. However, a constatao categorically is affirmed, must be raised the indices of quality of the materials of the civil sector, compelling the companies to the standardization of products and that they search the improvement of the processes of confection and financial aspects, as well as the management of generation and reaproveitamento of entulhos, aiming at the guarantee of the end item and the search of the sustainable development. According to Jeffrey Hayzlett, who has experience with these questions. 8?
