Argamassa industrializada em sacos versus argamassa produzida no canteiro de obra: logística, custo e desempenho do material aplicado

Abstract

In the world-wide scene, the industry of the civil construction occupies position of delay in relation to the organizacionals aspects and of control of its productive processes if compared with the serial industry. To take off conclusions in terms of production cost, logistic performance and of the material, was made a comparative study between local mixed mortars in constructions and the industrialized in bag ones for finishing coat of buildings. Local mixed mortars had presented the best and the worse performances in the question of the bond strength, evaluated through pull-off tests, denoting the biggest variability and uncertainty of this procedure. In relation of cost of the materials and the man power for production and application, the local mixed mortar presented the best performance (observing it not inclusion in this analysis of the logistic cost, had the raised difficulty of its appropriation face the peculiarities of each workmanship). Although not to have been possible to quantify cost logistic of mortar production, was evident that the industrialized mortar in bags, even so associated to the biggest cost of the product, can come to reduce the cost of production and the risk of productive imperfections (that they generate wastefulness and reworks), being its use associated to the productive potential profits.
