World is growing and urbanising at a very fast rate and so is India. This effect of rapid urbanization is also seen in construction industry. However, with urbanisation comes the moral responsibility of sustaining the environment. Concrete is the favourite choice as a construction material among civil engineers around the globe for decades. It is … Recycled Aggregate Concrete: Applications, Advantages & …
In this paper, C25 waste road concrete is used as an experimental material, the uniaxial compression strength and tensile splitting strength of C25 RAC whose coarse aggregate replacement rate is 0%, 25%, 50%, 75%, and 100% are tested under the condition that the water-to-cement ratio is 0.47, 0.55 and 0.61.

beneficial. Recycling is an important process which is used to produce a useful source of aggregate for the construction industry. Concrete recycling is increasingly becoming popular way of utilizing aggregate left behind demolished structures, road construction materials and site waste materials. In the past, demolished structural
UNIMAS E-Journal of Civil Engineering, Vol. 1: issue 1 /August 2009 1 Abstract In this rapid industrialised world, recycling construction material plays an important role to preserve the natural resources. In this research, recycled concrete aggregates (RCA) from site ...
recycling are lacking, but it is reasonable to expect that more than 5 million tons of recycled aggregate is used annually in the state (Wolfe, 2011). One of the most common recycled materials and the focus of this paper is recycled concrete aggregate (RCA). RCA production was estimated at 95 million tons in
At the same time, there is enormous amount of demolished concrete from deteriorated and obsolete structures generating waste material. It creates disposal problem and is an ecological and environmental problem. Recycling concrete is a viable alternative to using natural aggregate in concrete construction.
the demolished concrete aggregate 10%, 20%, 30% by weight of the conventional coarse aggregate and the concrete cubes were casted by that demolished concrete aggregate then further tests conducted such as workability , compressive strength for that DAC and the result obtained are found to be comparable with the conventional concrete.
Also, the recycled aggregate concrete showed lower modulus of elasticity and durability characteristics. Al-Mutairi and Haque used old demolished concrete in Kuwait to replace 50 and 100% of the coarse aggregate and seawater to replace 25, 50, and 100% of the tap water in a standard concrete mix having moderate target strength. The recycled ...
The appearance of the recycled crushed aggregate, based on "demolished" concrete (various fractions) is shown in Fig. 2 [1, 20]. Naturally, the quality and characteristics of the concrete made with the recycled aggregate will directly depend on the properties of the used recycled aggregate.
Jun 22, 2001 · Recycling and reuse of waste such as building rubble, concrete lumps, etc. generated at construction and demolition sites form part of a wider, complex issue, primarily relating to improving supplies of construction material and solving problems of disposal of waste construction material. Within the framework of the sustainable development of the environment, the use of waste materials with ...
materials are increasingly judged by their ecological characteristics. Recycling of demolished concrete is gaining importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or other applications.2 The demand of concrete expected to
1996/03/01 · Experimental work was performed to determine the compressive, splitting tensile, and flexural strengths of recycled coarse aggregate concrete and to compare the Title: Strengths of Recycled Aggregate Concrete Made Using Field-Demolished Concrete as Aggregate ...
Authors: Smitha Yadav, Snehal Pathak Abstract: Aggregate compositions in the construction and demolition (C&D) waste have potential to replace normal aggregates. However, to re-utilise these aggregates, the concrete produced with these recycled aggregates needs to provide the desired compressive strength and durabil
Abstract: Recycling of concrete demolition debris obtained from reconstruction projects of structures and highways has been considered for many years. Recycling demolished concrete as aggregate helps to overcome environmental and economic problems of obtaining quality aggregate from natural sources and to facilitate concrete disposal.
The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates. Most agencies specify using the material directly in the project that is being reconstructed. Recycling of concrete is a relatively simple process.
Based on this perspective, it is realized that concrete industry can be made sustainable through recycling of the demolished concrete. RECYCLED AGGREGATE . Recycling is the act of processing the used material for use in creating a new product. The usage of natural aggregate
This new RILEM report contains state-of-the-art reviews on three topics: recycling of demolished concrete, recycling of masonry rubble and localized cutting by blasting of concrete. It has been compiled by an international RILEM Committee and draws on research and practical experience worldwide.
The recycling of demolished masonry rubble as coarse aggregate in new concrete represents an interesting possibility at a time when the cost of dumping such material is on the increase.

crushed concrete with aggregate. Recycling of demolition debris was started since the end of 2nd world war, which used crushed brick as aggregates in concrete . Using crushed concrete from demolition waste as aggregate instead of natural resources as well as using demolished concrete pavement to stabilize the road base
Recycled aggregate occurs as either recycled concrete aggregate (RCA) or recycled asphalt pavement (RAP). Recycling concrete and asphalt has been taking place in the USA since at least the early 1970s (Nanasy 1972), and by the 1990s was a well-established activity.
