Reactivity in Recycled Concrete Aggregate
Full scale tests with crushed concrete used in sub-bases in roads show that the material has capacity to reharden, very slowly but also after prolonged periods of time. The rehardening process in crushed concrete aggregate has been analysed with a thermogravimetric method, comparing the change in chemical composition in the aggregate when set with water, compacted and hardened. It has been show...
متن کاملAssessing relationships among properties of demolished concrete, recycled aggregate and recycled aggregate concrete using regression analysis.
Recycled demolished concrete (DC) as recycled aggregate (RA) and recycled aggregate concrete (RAC) is generally suitable for most construction applications. Low-grade applications, including sub-base and roadwork, have been implemented in many countries; however, higher-grade activities are rarely considered. This paper examines relationships among DC characteristics, properties of their RA and...
متن کاملComparative performance of concrete pavements with recycled concrete aggregate (RCA) and virgin aggregate subbases
Using recycled concrete aggregate (RCA) as base/subbase for road construction is alternative way to manage construction waste and reduces the need for virgin aggregates. This paper discusses the long-term performance of concrete pavements on RCA granular layer in comparison to concrete pavements on virgin aggregate granular layer. 18 representative RCA pavement sections across Iowa were primary...
متن کاملCreep of Concrete with Substitution of Normal Aggregate by Recycled Concrete Aggregate
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...
متن کاملPerformance of Continuously Reinforced Concrete Pavement Containing Recycled Concrete Aggregate
In 1995, the Texas Department of Transportation (TxDOT) began reconstruction in Houston on a section of IH-10 with continuously reinforced concrete pavement (CRCP). The unique aspect of this project was the use of crushed concrete as both coarse and fine aggregates in the new concrete. No virgin aggregates were used. The primary objectives of this study were to evaluate (1) the material propert...
