characteristics of recycled concrete

The characteristics, those are the failure, compressive strength, cracking were analyzed. Based on that, compressive strength of recycled fibre concrete has clearly changed in comparison with recycled concrete when subjected to temperatures of 200 C - 500 C.

  • Performance characteristics of recycled concrete aggregate

    Use of recycled concrete aggregates (RCA) as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA, such as elastic and plastic deformations of RCA is therefore, needed to assess RCA's applicatio …

  • Characteristics of Recycled Concrete Aggregates from

    Therefore, properties of recycled concrete aggregates (RCA) produced from construction and demolition waste (C&DW) of precast slab block buildings build between 1950s to 1990s are not sufficiently known. The demolition of these buildings is very rare today, but it can be assumed an increase in demolitions of these buildings in the future.

  • PROPERTIES OF RECYCLED AGGREGATE CONCRETE

    application of coarse recycled concrete aggregate, as the component materials in the con-crete mixtures, it is possible to produce structural concrete that can be satisfactory and even with high quality, which primarily depends on the characteristics of crushed demolished concrete.

  • Strength Characteristics of Recycled Concrete after

    Due to the recycling of construction waste, recycled concrete has gradually become a viable material in the construction industry. To study the strength property of the recycled concrete after freeze-thawing experiments, recycled concrete and ordinary concrete were tested for their post-test strength after freeze-thawing for 0, 50, and 100 times.

  • Liquefaction characteristics of recycled concrete

    May 01, 2019 The results from a series of repeated load triaxial tests on recycled concrete aggregate (RCA), crushed bricks (CB), and waste excavation rock (WR) reported that most of the recycled C&D materials produced comparatively smaller permanent strain and greater resilient modulus than those of the commonly used granular subbase natural materials .

  • Pore characteristics of recycled aggregate concrete and

    Feb 22, 2021 However, the characteristics of micro pores for concrete, especially for recycled aggregate concrete, under the coupling action of various environmental factors were rarely studied. Concrete is a typical porous material with wide pore size distribution, different pore types and …

  • Recycled Aggregates Portland Cement Association

    Recycled Aggregate Characteristics. The crushing characteristics of hardened concrete are similar to those of natural rock and are not significantly affected by the grade or quality of the original concrete. Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests required ...

  • Strength and Deformation Characteristics of Recycled

    May 07, 2012 May 07, 2012 To investigate the feasibility of the use of recycled concrete aggregate as the backfill material of geotechnical engineering structures, such as embankments, geo-synthetic reinforced soil retaining walls and bridge abutments, a series of drained triaxial compression tests were performed. Both axial and lateral strains were measured locally.

  • Durability characteristics of recycled aggregate concrete

    The strength and durability characteristics of recycled aggregate concrete can be improved in a much better way by using the treated recycled aggregates in concrete. View Show abstract

  • An evaluation of the recycled aggregate characteristics

    Apr 20, 2020 At present, compared with other recycled coarse aggregate types, recycled concrete aggregate is the most extensive implemented RA in construction, and organizations in many countries have developed specifications , , . In this paper, the performance and application of recycled concrete aggregate were focused on.
