However, the current results show the possibility of recycling the construction and demolition (C&D) waste into building materials because 85% of tested concrete blocks produced from recycled aggregates, have achieved 7 N/mm2 as a minimum strength for load bearing capacity in Tanzania.
NEED OF PROJECT Reuse and Recycling of construction & demolition wastes seems workable solution in rehabilitation and new constructions after the demolition of old construction. Central Pollution Control Board has estimated 52 million tons per annum solid waste generation in India out of which, 70-80 million tons are concrete and brick waste.
to concrete strength, concrete made with GGBFS continues to gain strength overtime, and has been shown to double its 28-strength -day over periods of 10 to 12 years. Our project is a testing project compared with the compressive strength of PCC and GGBFS, used concrete. Here the amount of cement is reduced and that amount is replaced with GGBS.
concrete strength. Yasuhir et al.  studied about the development of a sustainable concrete waste recycling system. The recycled coarse aggregate using the aggregate replacing method can acquire sufficient quality as structural concrete. This developed recycling system is applicable to scrap and build of general buildings.
The green concrete has less split tensile strength than the ordinary concrete. In the eco-friendly concrete, the cost of the reinforcement increases with the use of stainless steel. A detailed life cycle analysis of green concrete by considering different parameters is must to understand the resultant concrete properties.

landfills. Recycling concrete by using it as replacement to new aggregate in concrete could reduce concrete waste and conserve natural sources of aggregate. In the last two decades, varieties of recycling methods for construction and demolition wastes have been explored and are in well-developed stage. Fly ash is known to be
Most of waste materials produced by demolished structures disposed off by dumping them as land fill. Dumping of wastes on land is causing shortage of dumping place in urban areas. Therefore, it is necessary to start recycling and re-use of demolition concrete waste to save environment, cost and energy.
sludge as a source of water in concrete production has insignificant effect on compression strength, while it has a sharp effect on the slump values. K. Pazhani, R. Jeyaraj showed study on durability of high performance concrete with industrial wastes using copper slag and ground granulated blast furnace slag (GGBS).
w/c ratio. At lower w/c ratios, the compressive strength of recycled concrete is much lower than that of normal concrete and also higher w/c ratio give similar strength of conventional concrete. III.

same properties and strength as that of the ordinary Portland cement. My study is based on the use of GGBS and silica fume in place of cement and to investigate the properties at different proportions. Index Terms- GGBS, Silica Flume, Concrete INTRODUCTION Concrete is the second most used material in the world after water.
2010 International Concrete Sustainability Conference, Dubai, UAE 10 Test Program The recycled aggregate was obtained from a demolition construction waste at Emirates Recycling Pty Ltd in Dubai. “Emirates Recyygcling” is an million joint venture between Al Rostamani Group and the Italian General Work infrastructure development company ...
Strength can be defined as ability to resist change. One of the most valuable properties of the concrete is its strength. Strength is most important parameter that gives the picture of overall quality of concrete. Strength of concrete usually directly related to cement ...

Concrete has shaped the modern world. Other than water, it is the most widely used material on the planet so it's unsurprising that scientists are constantly working to make it safer, stronger and ...
Powder and GGBS. The compressive strength of partially cement replaced concrete made with 5, 10, 15, 20, 25 and 30% Egg Shell Powder and 25% of GGBS ranges from 16.29 to 18.43 MPa at 7 days and 31.33 to 37.10 at 28 days From the Experimental Results it is clears that the compressive strength of concrete made with 15% ESP and 25% GGBS shows ...
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
In view this silica fume (SF), ground granulated blast furnace slag (GGBS), rice husk ash, fly ash (FL), metakolin, alccofine (AL), micro fine material, etc.; are tried out for replacing cement partially or fully in concrete, without compromising on its strength, also reduce greenhouse gases and sustainable way of management of waste.

Concrete made with GGBS continues to gain strength over time, and has been shown to double its 28-day strength over periods of 10 to 12 years. [ citation needed ] The optimum dosage of Ground granulated blast-furnace slag (GGBS) for replacement in concrete was reported to be 20-30% by mass to provide higher compressive strength compared to the concrete made with only cement.
concrete cannot be used. (At maximum cement content, the highest strength class that may be assumed for structural design is C20/25.) The strength of the concrete cannot be specified and the cement content tends to be significantly higher than that for a designed or designated concrete. Do not use this method if a lower-carbon concrete is required.

We need to increase use of classified fly ash by processing fly ash into different categories based on its fineness so that it can contribute effectively in producing very high strength as well as normal strength and durable concrete with lower cement utilization. Recycling of concrete from C&D wastes.
May 09, 2018 · The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components
