Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cement-based materials, due to its good physical, chemical and mineralogical properties. Particularly the re-use as coarse aggregate for concrete production has been shown to ...(PDF) Structural Behaviour of Concrete With .In this experiment the studies, the strength characteristics of M30 grade concrete are using manufactured plastic coarse aggregate as a replacement of natural coarse aggregate is conducted along with the use of quarry dust as a partial replacement ofRECYCLED TIRES AS COARSE AGGREGATE IN CONCRETEtire 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 the air content reached 6%. At 28 days of age, the average compressive strength of the two mixtures was 4735 psi. Although this strength was ...(PDF) Lightweight Concrete Using Coconut Shells as AggregateConcrete incorporated with 10%, 20% and 30% volume fraction replacements for fine aggregate was designed for target strength of 35 MPa to note percentage replacement effects on the structural ...
