Abstract
The study of the incorporation of tire rubber waste in concrete has been conducted for over ten years. Its actual application in piles, however, especially in bored piles, has no record in technical or scientific literature. The motivation for this research has derived as much from environmental convenience as from sustainability, and it aims at validating the use of this concrete in the manufacturing of small caliber bored piles without the use of stabilizing fluid, which is the recommended foundation for small and medium-sized constructions in the Northwest of São Paulo State. Rubber waste is a large-scale globally produced environmental liability of extreme relevance, especially as a substitute for non-renewable natural materials. In order to assess this variety of concrete in foundations, six bored piles have been manufactured, 0.3m in diameter and 6m long, three of which were made of conventional concrete, and the remainder used rubber waste in its composition. The results obtained in terms of compression resistance, elasticity modulus, load capacity and load transfer to the ground have validated the use of rubber waste in the manufacturing of bored piles

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
