MÉTODO DE DOSAGEM DE CONCRETO IPT -- ESTUDO DE CASO.

The research aimed to demonstrate the efficiency of dosing by the IPT method, with regard to the economy of materials and the best strength and durability gain. Calculations were made to determine the materials proportion used in each of the following traits: basic (1:5), rich (1:3,5) and poor (1:6,5), and 9 proof bodies were molded. Using a concrete mixer, the materials were mixed until they reached the proper consistency of the concrete and, afterwards, the compressions were measured after 7 days for each specimen. After 7 days, compression tests of the specimens were performed and then graphs for strength, cement consumption and mass were plotted. It was noted that the use of the IPT method becomes more efficient, since it is allowed to obtain the proportions of each material in advance, thus avoiding waste and generating savings on site.
