The Compressive Strength and Flexural Strength Test of Recycled Pebble Aggregate Concrete

Article Preview

Abstract:

Primary concrete of pebble coarse aggregate were used as the source of recycled aggregate concrete for pebble recycled coarse aggregate. Replacement rate of recycled aggregate for change parameter, 99 specimens were designed. The prism compressive strength, cube compressive strength and flexural strength were tested and achieved. The test results show that damage process and form of pebble coarse aggregate concrete are similar to those of normal concrete. It is gel adhesive failure between coarse aggregate and cement. Comparing with natural aggregate concrete, the strength indexes of recycled aggregate concrete of pebble coarse Aggregate slightly increase.
