Abstract:

Large quantities of construction and demolition waste is generated annually around the world. Part of this material is processed in recycling plants. After removing metals, fines and lights, the construction and demolition waste is crushed and sized and can be used as aggregates for low resistance concrete, for road sub-base, city landfill and other low value-added applications. For their use as coarse aggregate in structural concretes, construction and demolition waste must exhibit high densities and regularity of the material. This material usually is presented in demolished concretes. About

Abstract:

The construction sector generates substantial waste, including demolished concrete, presenting environmental challenges and disposal expenses. This study introduces the DWARF (Demolished Waste as Resource for Sand in Concrete) technique, an innovative method that repurposes demolished waste as a valuable resource for replacing sand in concrete production. The DWARF process involves treating the demolished waste to meet specifications for sustainable use as an alternative to natural sand in concrete mixes. This research investigated the feasibility and effectiveness of the DWARF technique conce

<em>The increasing demand for sustainable construction practices has driven research into the use of demolished and industrial waste as replacements for conventional aggregates in concrete. Developing reliable methods to predict the compressive strength of concrete incorporating such waste is critical for ensuring consistent performance. This paper explores the application of the Taguchi method to derive a robust equation for predicting the compressive strength of concrete blocks made from demolished and industrial waste. The Taguchi approach, known for its efficiency in optimizing processes w

Abstract:

Concrete is highly utilized construction material around the globe and responsible for high depreciation of the raw materials. Consumption of this material in construction industry is arching upward day by day. On the other hand, debris of demolished concrete structures are being dumped as waste. For developing countries such waste is not a good sign and need its proper utilization by recycling it into useful product. In this consequence, this study is an attempt to utilize demolished waste concrete by converting into coarse aggregates. This research was conducted on recycled cement concrete a

Abstract:

Double thin skin hybrid walls filled with demolished concrete lumps (DCLs) are composed of two steel plate skin connected by rib plates, with the space between them filled with new concrete and demolished concrete lumps. In order to investigate the seismic behavior of double thin skin hybrid walls filled with DCLs, quasi-static tests of seven specimens were conducted. The parameters considered in the tests are: replacement ratio of DCLs, thickness of steel plate, axial load ratio, rib plate spacing and height-width ratio. Test results show that the seismic performances of double thin skin hybr

Abstract:

ABSTRAKBeton daur ulang merupakan campuran dari agregat kasar atau agregat halus daur ulang. Salah satunya dibuat dari hasil bongkaran pelat beton perkesaran kaku jalan (rigid pavement). Pembongkaran ini disebabkan oleh kerusakan, keretakan dan keausan pada perkerasan kaku yang diakibatkan oleh beban kendaraan. Bongkaran beton tersebut seringkali dibuang di sembarangan tempat atau hanya menjadi bahan urugan saja. Hal ini tidak menguntungkan, sehingga pada penelitian ini, bongkaran perkerasan kaku tersebut dijadikan sebagai agregat daur ulang. Pemanfaatan bongkaran beton ini merupakan perkemban

Abstract:

Combining with the utilization of waste, an new idea of using the waste to prepare high-strength artificial aggregates was put forward in this paper. The concrete was also prepared by using these aggregates. The demolished concrete could be recovered and used as cement raw meal to produce new cement clinker. In this study, the feasibility of making cement clinker with this kind of demolished concrete was studied. The concrete aggregates composed of steel slag, blast furnace slag, coal gangue and fly ash were prepared. The concrete was prepared using these aggregates with the water-cement ratio
