This paper and consists of two sections. At first a literature review is presented, describing the main aspects of the high strength concrete, it is expected that the material presented is useful in subsequent research. The following section describes the experimental work, which involves the analysis of reinforced concrete beams. He was employed high strength concrete (up to 53 MPa) and the beams were subjected to bending. The concrete used had no additives or adding microsillen chemicals.Were analyzed variations in mechanical behavior as a function of cross section dimensions, concrete strength and Rate frame.Os results suggest the variety of procedures described by NBR 6118 calculation for bending in the range of resistance values of the above mentioned lifetime factor coincide with the data obtained from literature.
