Used Of Recycled Tyre/Rubber as Course Aggregate and Stone Dust As Fine Aggregate in Cement Concrete Works
The present investigation aims at the study of properties of concrete in which stone dust is used as a partial replacement for coarse sand and tyre-chips of size 4.7 to 10 mm as partial replacement of coarse aggregate by weight.
متن کاملRecycled Plastics as Coarse Aggregate for Structural Concrete
The use of plastic is increasing day by day, although steps were taken to reduce its consumption. This creates substantial garbage every day which is much unhealthy. A healthy and sustainable reuse of plastics offers a host of advantages. The suitability of recycled plastics as coarse aggregate in concrete and its advantages are discussed here. The initial questions arising of the bond strength...
متن کامل“recycled Plastics Used as Coarse Aggregate for Constructional Concrete”
Landfill sites are becoming over crowded and expensive for waste disposal, efforts are made to minimize the quantities of materials that are delivered to landfills. The threat due to leaching of non-biodegradable materials like waste plastics, scrap tyres. e-waste may contaminate the soil and ground water. If the production of waste cannot be prevented, then it is attractive to create an altern...
متن کاملRecycling of harbor sediment as lightweight aggregate.
Sediment sampled from Taichung Harbor was mixed with local reservoir sediment at different weight ratios to prepare lightweight aggregate at 1050, 1100, and 1150 degrees C. A pressure of 3000 or 5000 psi was used to shape the powder mixtures into pellets before the heating processes. The results indicate that the leaching levels of trace metals from the lightweight aggregate samples are conside...
متن کاملSeismic Performance of Composite Shear Walls Constructed Using Recycled Aggregate Concrete and Different Expandable Polystyrene Configurations
The seismic performance of recycled aggregate concrete (RAC) composite shear walls with different expandable polystyrene (EPS) configurations was investigated. Six concrete shear walls were designed and tested under cyclic loading to evaluate the effect of fine RAC in designing earthquake-resistant structures. Three of the six specimens were used to construct mid-rise walls with a shear-span ra...
