Abstract

Precast and prestressed concrete piles, approximately 12 to 18 inch diameter or width are frequently used to support heavy building and bridge structures. Fly ash has long been recognized as a construction material used frequently in several Portland cement and concrete products, structural fills, embankments, and road bases/subbases. However, use of Illinois PCC bottom ash in construction of precast concrete piles so far has been very limited, if any, mainly due to the lack of technical data to convince the engineering community that bottom ash could be used in precast and prestressed concrete piles without jeopardizing their performance and the structural integrity to resist the anticipated loads. The main objective of this investigation was to evaluate the effect of using Illinois PCC bottom ash on the performance of precast concrete driven piles when subjected to axial loads using O-Cell. This goal was accomplished by performing field tests on full-size piles made with concrete composites containing Illinois PCC bottom ash and comparing their performance with the performance of a similar pile made with an equivalent conventional concrete. The test results show that that the performance of piles made with concrete composites was similar to that of piles made with an equivalent conventional concrete.

O-Cell Testing of Reinforced Concrete Driven Piles

Precast and prestressed concrete piles, approximately 12 to 18 inch diameter or width are frequently used to support heavy building and bridge structures. Fly ash has long been recognized as a construction material used frequently in several Portland cement and concrete products, structural fills, embankments, and road bases/subbases.
