Performance Characteristics Of Recycled Concrete Aggregate

Use of recycled concrete aggregates RCA as a pavement material is one of the most sustainable engineering applications for the pavement industry. Investigation on the performance characteristics of RCA, such as elastic and plastic deformations of RCA is therefore, needed to assess RCAs application as an unbound pavement material. In this study, repeated load tri-axial RLT tests were ...

Effect Of Recycled Coarse Aggregate On Concrete Properties

Recycled aggregate can absorb more water than natural aggregate because recycled aggregate has many pores to absorb the water and it will influence the characteristic Strength. Modulus Elasticity Based on the research result, it can be seen that the increase of Recycled Aggregate will decrease the value of modulus elasticity.

Physical Characteristic Of Ready Mixed Concrete With

Researches until now about recycled aggregate have mainly focused on illuminating physical properties and mechanical behaviors of recycled aggregate by experimenting on small batches of mixing. Unfortunately this kind of mixing does not necessarily fit the reality where a large amount of ready-mixed concrete is often made. Therefore, this study carried out an experiment by having a ready-mixed ...
