Construction is one of the most expressive industries in the national economy, employing aroung 8 million workers in the country. Between the most used materials, concrete is the most used input in this branch, besides to being the secong most consumed material in the world. Commonly, reinforced concrete are molded in loco, respecting a minimum period of 7 days to take it out of the molds, and another 14 days for their satisfactory drying and cure. With the bigger demand for better materials and shorter deadlines, newer construction pratices gained ground: such as prefabricated concrete estructures. Which have the same reinforced concrete dimensioning, however, with molded parts in a different location from their final disposal. In disagreement with the presented advantages, civil construction activities causes great environmental impacts. According to recente surveys, brazilian cities collects about a hundred and twenty thousend tons of civil construction waste (RCC) Every day. Studies that address the reuse of RCC still have some limitations, especially regarding the quality of the waste used. Therefore, this assignment aims to use the concrete waste genereted by the a prefabricated concrete estructures industry, located in the city of Irati – PR. The collected residues were reduced for use as recycled aggregate for concrete in different contents. After molding the concrete test cylinder, they were aveluated for strenght in na axial compression test. |
