Life Cycle Assessment of Sustainable Concrete Made With Recycled Aggregates
The results of an environmental study on concrete manufacture that follows the standard protocol of life cycle assessment are shown in this document. The study has been done for seven types of concrete: one conventional and six containing cement kiln dust (10%), marble sludge (10%) and demolition waste (10%, 80% and 100%) respectively, in partial or total substitution of natural aggregate. Six ...
متن کاملLow Cycle Fatigue Behavior of Concrete with Recycled Concrete Aggregates
A comparison of concrete containing recycled concrete coarse aggregates and natural coarse aggregates subjected to high strain, low cycle compressive fatigue is presented. Using a strain based feedback control loop, concrete cylinders are compressed at 15µε/s to a specified strain then unloaded to zero stress for 10 cycles. After cycling, all samples are loaded to a strain of 0.008. Direct conc...
متن کاملIn situ strength assessment of concrete using recycled aggregates by means of small diameter cores.
By increasing the demolition of old concrete structures and the interest of civil industries to consume cheaper materials, using Recycled Concrete Aggregate (RCA) can cause environmental protection and decrease the construction costs. On the other hand, the high potential of Recycled Aggregate Concrete (RAC) in concrete industry was established by extensive experimental researches were performe...
متن کاملPerformance of High-strength Concrete Made with Recycled Ceramic Aggregates
Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...
متن کاملToughness Performance of Recycled Aggregates for use in Road Pavement
The policy of driving organization such as Highways Agency is towards the use of performance related specifications. This policy and adoption of European wide aggregate standards on the one hand, and sustainable construction pressures on the other, all strongly emphasize on further need for more developments to specifications and performance assessment methodologies inst...
