  • Theoretical analysis and finite element modelling of composite ferrocement–concrete beams

    Composite ferrocement–concrete beams have been introduced in the literature as a viable alternative for the conventional reinforced concrete beams. This paper presents a proposed theoretical and a three–dimensional non–linear finite element models for simulating and analysis of composite ferrocement–concrete system. The theoretical and the finite element models were used to analyse ten composite ...

  • Material flows analysis of construction aggregates in Taiwan

    Recent decades of economic and industrial development have accelerated the demand for and use of construction aggregates in Taiwan. Material Flows Analysis (MFA), the most common analysis tool of the scientific field of industrial ecology, was employed in this study. The study calculated, within a decade period, the deposits, domestic production, demand, import, export, per capita and per unit ...

  • Hydro-Vortex implementation in ReadyMix’s concrete plant (Israel) Case study

    ReadyMix concrete plant near Tel Aviv, Israel, was established in March 2000 to produce concrete. The plant includes a pre-mix facility for concrete production, supported by a concrete recycling ...

  • Aggregates Research: Engineering properties of concrete containing recycled aggregates

    The objective of this project (AGG0079-002) was to identify whether the use of recycled concrete aggregate (RCA) affects the applicability of engineering property relations for concrete based on compressive strength given in the structural design Eurocode EN1992 [1] which is referred to here as EC2. It was also to determine whether the ultimate strength of concrete structural members containing ...

  • Raising awareness on materials recycling using undergraduate engineering research

    Undergraduate research in engineering was used as a means of raising awareness on materials recycling and alternative recycled material products and processes. Over a three-year period, the authors hosted undergraduate researchers to work on rubber and polymer concrete, rubber-sandwich structures and recycled rubber materials for road embankments and retaining wall backfills. This paper discusses ...

  • Ready, set... mix: water re-use and its role in concrete mixing

    Water is a key element to the concrete ready-mix manufacturing process. From mixing new concrete to cleaning out trucks, high volumes of water are in demand. To stay ahead, many operations, large and small, are prepared to re-evaluate their process to find opportunities for water re-use. A filter press is an effective piece of equipment for concrete water recycling. It separates ...

  • Use of asphalt plant residue in hot mix asphalt

    Environmental solid wastes increase more and more as a result of the industrial waste production day by day. Management of the solid wastes is the thrust area for researchers. In this study, the effects of asphalt plant residue (APR) on the properties of hot mix asphalt (HMA)s are investigated. APR was added into the asphalt concrete in 25, 50 and 100% by weight of the filler. In order to ...

  • Performance of an enhanced pervious pavement system loaded with large volumes of hydrocarbons

    Five litres of lubricating oil and two 8.5 litre batches of diesel were deposited on each of two hydraulically isolated experimental enhanced pervious pavement parking bays. The 50 mm aggregate subbases of the two bays were of either recycled concrete or crushed limestone. The bays were constructed in such a way that a near-surface gravity separator was created by the arranging of the outlet ...

  • Recycling crushed glass in concrete mixes

    A strategy using recycled glass as aggregate replacement in concrete is presented in this paper. The properties of fresh and hardened concrete made with fine and coarse crushed glass are presented and discussed. Proportions of 0?100% of crushed glass are implemented in the concrete specimen and the compressive strength up to 700°C is measured. The results indicated that the use of crushed glass ...

  • Testing of concrete to determine the effects on groundwater

    The need for a more sustainable construction industry, as well as increasing pressures on landfill space, have led to an increasing use of recycled and secondary materials as aggregates in concrete1,2. However, if users are to have full confidence in these materials, it is important that they are shown to have neither an adverse impact on the properties of concrete, nor on the environment, ...

  • How can we reduce concrete’s hefty carbon footprint?

    A roomful of materials scientists, gathered at UCLA for a recent conference on “grand challenges in construction materials,” slowly passed a brick-size white block around the room. They held in their hands, briefly, part of the solution to one of those grand challenges. The white block, rock solid and surprisingly lightweight, was a new alternative to cement, the glue that holds ...

  • Similarities and synergies between mineral processing and recycling of Construction and Demolition Waste

    Recycled aggregates from Construction and Demolition Waste (C&DW) can replace natural aggregates in applications such as road construction and concrete production, but in the latter instance there are stringent quality requirements. This paper proposes the application of mineral dressing concepts to the characterisation of C&DW. The main strengths and drawbacks of dry and wet separation processes ...

  • Reusing Recycled Tires: 5 Benefits of Recycled Rubber Retaining Blocks

    According to the Recycled Times, over 300 millions used truck and car tires are accumulated every year. At least 25% of those tires are being put into landfills, which means that every year in the U.S., 75 million tires are taking up space in a landfill when they could be reused for something better. To put this information into perspective, for every three people in the United States, there is ...

  • Recycling efficiency in the construction industry

    Construction clients, policy makers and planners are increasingly setting requirements to encourage greater use of recovered materials in construction. A number of construction clients and product manufacturers have shown a desire to expand the consideration of materials efficiency to include recyclability as part of the sustainable construction agenda. Potentially there are significant benefits ...

  • Power Industry: Noxious Fumes at TVA Handled by Scrubber Case Study

    To keep the work area free of noxious fumes and reduce atmosphere pollution, T.V.A. Wilson Dam uses a 36″ diameter Clean Air Group fume scrubber to handle 12,500 cfm of gas @ 150°F in their high-analysis super phosphate operations. Manufacturing high analysis super phosphate fertilizer at the TVA Wilson Dam operation creates noxious fumes. Most of these fumes are liberated during the ...
