tire chips can be used to replace coarse aggregate in concrete pavement mixtures. Two mixtures with 10% coarse aggregate replaced by tire chips and normal cement content had the best performance. The workability was comparable to the control mixture, and

behavior of recycled aggregate in concrete structures. experimenting fresh and hardened concrete, mixtures containing recycled aggregates. The percent of fine recycled aggregate in the all recycled aggregate was about 5.0% so it was excluded from the stud

2.2. Experimental Methods. The recycled fine aggregates, having a size of 5 mm or less, used in this experiment were obtained from Green and Environments Co., Cheonan, Korea and their physical properties are shown in Table 3. Additionally, the washing wat

The addition of fly ash in recycled aggregate concrete has two methods, named equivalent replace and super-substitute technique. The workability of fresh concrete, compression strength, spilt and flexural strength of recycled aggregate concrete with diffe

natural coarse aggregate with recycled coarse aggregate with addition of steel fibers are satisfactory. It has been observed form the experimental work that compressive strength results are improved with increase in percentage of steel fiber with replace

Nov 07, 2016 · The use of 100% recycled coarse aggregate in. II. METHODOLOGY Materials The entire experimental study was conducted at the concrete laboratory of Pondicherry Engineering College, Puducherry, India.

Although being a mainly conceptual methodology, the proposed formulation is supported by a wide set of experimental results: they unveil the influence of several aspects and parameters (such as source and processing procedures of RCAs, aggregate replaceme

The construction industry is responsible for 50% of the consumption of natural resources. The importance of recycling construction materials has been emphasized owing to the depletion of natural resources. A strategy to overcome the supply shortage of nat

the waste glass as partial replacement for both fine aggregate and coarse aggregate separately. For this M 20 grade of concrete was used with a mix proportion of 1:1.5:3 and with water cement ratio as 0.5 concrete specimens were moulded with 0%,10%

In this paper, we present the experimental analysis of samples of recycled concrete (RC) with replacement of natural aggregate (NA) by recycled aggregate originating from concrete (RCA).

An experimental study of recycled aggregate concrete (RAC) using recycled coarse aggregate (RCA) is reported. The RCA was obtained from construction and demolition waste (C&DW) and used as full replacement of natural coarse aggregate (NCA) for production

site. On the view of waste recycling material in this research paper Aluminium caps of beverages bottles are selected as partial replacement for the coarse aggregate in the concrete. The study is initiated with 10% replacement of coarse aggregate. By usin

Properties of Coarse Aggregate(Recycled and Natural) Particle Size Distribution The result of sieve analysis carried out as per IS 2386 for different types of crushed recycled concrete aggregate and natural aggregates. It is found that recycled coarse agg

May 14, 2015 · Experimental research on the flexural strength of recycled coarse aggregate concrete. Paper presented at the 2010 international conference on mechanic automation and control engineering (MACE), Wuhan, China.

In this paper, three recycled coarse aggregates (RCAs) with different 24-h water absorptions (5.67, 3.12, and 1.98 wt%) were used to produce recycled coarse aggregate concretes (RCACs). Different water absorption rates were obtained by modifying the surfa
