Green Piece -- Recycled Concrete Aggregates

Concrete with recycled concrete aggregate will exhibit slightly higher drying and shrinkage creep. Adherence to the gradation requirements of ASTM C33, “Standard Specification for Concrete Aggregates,” may be more difficult to achieve with recycled concrete aggregate because of the difficulty in controlling particle size during crushing.

Reclaimed Asphalt Concrete - User Guideline - Granular Base

RECLAIMED ASPHALT PAVEMENT User Guideline. Granular Base. INTRODUCTION. Reclaimed asphalt pavement (RAP) can be used as granular base or subbase material in virtually all pavement types, including paved and unpaved roadways, parking areas, bicycle paths, gravel road rehabilitation, shoulders, residential driveways, trench backfill, engineered fill, pipe bedding, and culvert backfill.

Evaluation of pre-coated recycled aggregate for concrete and

The test results show that physical performance of pre-coated recycled aggregate was within the range of specification requirement and surface-coated recycled aggregate with paste thickness of 0.035 mm resulted in a higher physical performance.

Comparison of recycled aggregate treatment methods on the performance for recycled concrete

Kong et al. pre-coated the recycled aggregate with pozzolanic materials using the triple mixing method, and then qualitatively evaluated the interface of the pre-coated aggregate using SEM. Zhao et al. [22] used sulfoaluminate cement and fly ash to pre-coat the recycled aggregate, and obtained the mixing ratio of the optimal slurry thickness.

Aggregates for Concrete

Key points • ‘Aggregate’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete

Evaluation of Effects of Recycled Concrete Aggregate on

This use of recycled concrete aggregate (RCA) as an HMA aggregate can be beneficial for constructing low-volume roads. RCA differs from virgin aggregates in that there is cement paste on the surface of the recycled concrete. In this study, 5% RCA was
