This paper reports the results of experimental investigations on recycled aggregate concrete. Properties of Recycled Concrete Aggregate Particle Size Distribution The result of sieve analysis carried out as per IS 2386 for different types of crushed recycled concrete aggregate and natural aggregates.
Recycled aggregate concrete (RAC) has several potential applications in floor systems. However, in the composite floor system with profiled steel sheeting, differential relative humidity occurs due to the thickness of slabs, and consequently leads to non-uniform shrinkage and creep deformations.
With the requirement of sustainable development and environmental protection worldwide, recycled concrete aggregate (RCA) has been commonly used as the new aggregate of concrete in recent years [1,2,3].According to studies in the literature [4,5,6], the coarse RCA has certain unbeneficial effects on the properties of new concrete, due to the special characteristics of a rough surface, a low ...

Mariaenrica Frigione (2010) had conducted an investigation on using recycled PET bottles as fine aggregate in concrete and concluded the workability, compressive strength, split tensile strength is slightly lower than referenceconcrete and moderately higher ductility.
the recycled aggregate concrete is almost 85% and 80% of natural aggregate concrete. Amn on.et.al (2002), concrete having a 28 -day compressive strength of 28 MPa was crushed at ages 1, 3 and 28 days to serve as a source of aggregate for new concrete,
Use of recycled aggregate in concrete can be useful for environmental protection. Recycled aggregates are the materials for the future. The application of recycled aggregate has been started in a large number of construction projects of many European, American, Russian and Asian countries. Many countries are giving infrastructural laws relaxation for increasing the use of recycled aggregate ...
This paper is about the usage of Recycled Concrete Aggregate (RCA) to replace 50% of natural coarse aggregate in the Concrete. Due to usage of Recycled Concrete Aggregate, strength of the concrete will be reduced. So to improve the strength of concrete, admixtures can be added in it.
Based on the years of extensive experimental rese-arch, and the research conducted by eminent experts, an overview is provided of the most basic properties and application of recycled aggregate concrete. It has been shown that the ... Mirjana Malešev, et al., Properties of recycled aggregate concrete
The present investigation was conducted to evaluate the influence of recycled aggregates on structural behaviour of reinforced concrete (RC) slabs. Concrete mixtures of 0.6 and 0.4 water/cement ratios were used to produce normal strength concretes and high strength concretes, respectively. Various concrete mixtures were prepared by replacing 19 mm natural coarse …
Recycled aggregate may be considered as a green material to some extent. It is quite well known that the porosity of recycled aggregate concrete is more than conventional natural aggregate concrete. concrete, unless carefully managed and controlled, is likely to have a negative influence on most concrete
