This work presents a study of the physical and mechanical performance of tests on two different traces of porous concrete, popularly known as permeable concrete. Currently problems related to flooding in areas of excessive occupation of impermeable soil has worried experts in urban drainage, the use of the type of concrete used in this research facilitates the surface runoff helping in the acceleration of the permeability of water coming from rains that cause flooding and floods mainly in poorly planned urban areas. Cement and water were used for the preparation of the samples and in order to ensure a greater safety in the variation of tensile strength of the specimens, 10 samples were made in the last proposed test until a difference rate was reached minimum between the result of the compression analyzes thus making a material that resists to areas related to the traffic of people like sidewalks, catwalks and even bike paths.
Concrete is the product most used in small and large buildings and the choice for the type of cement used varies between cost and quality, always meeting the specifications required by the standards. The objective of this work is to compare the results of the mechanical behavior between two brands of cement of the city of Manaus denominated for this research of CP I-T1 and CP I-T2, the choice for the model CP IS-40 is given by the practicality when working with a material of general use when no special properties are required, ie a product that can be applied in different stages of the work. In order to do this, a large number of tests were carried out on both the aggregate and the aggregate, so that it was possible to adopt a trace of concrete with a strict quality control in both brands, tests such as water absorption and resistance to axial compression were performed following a schedule of 07, 28 and 63 days after wet curing of the specimens.
