Synopsis: This study presents the experimental results on properties of concrete with replacement of natural aggregate by recycled concrete aggregate (RCA). Experimental data on the creep behavior of concrete mixtures (basic and drying creep) was obtained. The replacement factor of natural aggregate by RCA were 0%, 15%, 30%, 60% and 100%, and the test conditions were 50% RH and 20°C. The result...

There has been increased deconstruction and demolition of reinforced concrete structures due to the aging of the structures and redevelopment of urban areas resulting in the generation of massive amounts of construction. The production volume of waste concrete is projected to increase rapidly over 100 million tons by 2020. However, due to the high cement paste content, recycled aggregates have ...

In recent years, concrete has become a widely used material for general purposes in the structural area due to its excellent performance and properties. Hence, an increasing number of structures are built, huge amount building stock been occurred around world. However, because many progress (i.e., natural disasters), some demolished their status is changed into rubble, hence this becomes enviro...
