  • Construction Wastes: Types, Causes, and Recycling Construction Wastes: Types, Causes, and Recycling

    Recycling of construction waste is one way to counter risk to construction wastes. So, the invention of proper technology to recycle these materials is of great importance. For instance, concrete waste can be crushed and used as recycled aggregate

  • Concrete chokes our landfill sites – but where else can it Concrete chokes our landfill sites – but where else can it

    Feb 26, 2019 They agree, too, that this cannot happen without oversight: fines for dumping concrete waste, stronger regulation around recycled aggregate in

  • Geosciences | Free Full-Text | Waste Concrete Valorization Geosciences | Free Full-Text | Waste Concrete Valorization

    Concrete is a major constituent of our world. Its contributes to building society but is also an important contributor to the global CO2 emissions. The combination of waste concrete recycling and greenhouse gas abatement is obviously an interesting approach. Mineral carbonation is the methodology that allows the use of calcium oxide within the concrete and transform it into carbonates with the

  • Tires turned into graphene that makes stronger concrete Tires turned into graphene that makes stronger concrete

    Mar 29, 2021 Rice University scientists have optimized a process to convert waste from rubber tires into graphene that can, in turn, be used to strengthen concrete. The environmental benefits of adding graphene to concrete are clear, chemist James Tour said. “Concrete is the most-produced material in the world, and simply making it produces as much as 9%

  • Fatigue Performance and Multiscale Mechanisms of Concrete Fatigue Performance and Multiscale Mechanisms of Concrete

    Jan 02, 2014 Primary strengths, bending toughness, and fatigue performance of concrete with polymers or/and waste tire-rubber powders were evaluated. The optimized concrete mixture is recommended after investigation. Furthermore, the related nano-micro-macro-multiscale mechanisms of these concretes were also comprehensively investigated. 2

  • Development of optimized binary ceramic tile and concrete Development of optimized binary ceramic tile and concrete

    Indeed, only Ouda and Abdel-Aal [23] have studied the effect of ceramic waste replacements by concrete and calcined concrete wastes on the mechanical strengths of geopolymer binders. They employed an oven curing of 80 C, different NaOH molarities and water/binder ratios and obtained optimum strength of about 42 MPa for 90% CTW+10% CW combination

  • Recycling of concrete in new structural concrete Recycling of concrete in new structural concrete

    Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement

  • 2 Types of Concrete Crushers | HXJQ 2 Types of Concrete Crushers | HXJQ

    Aug 01, 2019 The development and utilization of waste concrete as a recycled material solves the problems of a large amount of waste concrete treatment and the resulting deterioration of the ecological environment; on the other hand, it can reduce the consumption of natural aggregates in the construction industry, thereby reducing exploitation of the natural sand and gravel, which has fundamentally solved

  • Sand Washer Improves The Cleanliness Of Concrete Sand Washer Improves The Cleanliness Of Concrete

    The high-performance concrete cleaned by the sand washer has a high volume stability, that is, the concrete should have a lower heat of hydration in the early stage of hardening and a smaller shrinkage deformation in the later stage of hardening.. High-performance concrete has a long service life. For some special parts of special projects, it is not the concrete strength that controls the
