specimens were moist cured. The test results proved that the compressive strength of concrete mixtures containing GGBS increases as the amount of GGBS increase. After an optimum point of 55% replacement, the addition of GGBS does not improve the compressive strength. The early strength of GGBS concretes was lower
Maximum strength values are obtained when 20% GGBS +15% Metakaolin is partially replaced with cement and Waste Medicine Wrappers is replaced with 10% Fine aggregates. Higher strength developed at optimum mix M2 due to pozzolonic reaction in concrete and
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.
Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete. The recycled concrete aggregates have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates.
A concrete mix of M30 is taken as the reference mix. Cement is replaced with GGBS with 0% and 10%.The effect of replacement of coarse aggregate by e-waste material and cement by GGBS on properties of concrete are studied for compressive strength and
demolished concrete waste for workability and compressive strength and split tensile strength. A. Objectives To reduce the waste. To reduce the demand of fine aggregate by the replacement of demolished concrete waste. The effect of natural sand mining from the river bed is reduced by demolition concrete waste.

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
strength obtained for concrete having FA and 10% GP was found to be the highest. Hence, it was decided to prepare concrete having FA, 10% GP and different percentages of GGBS to study the effect of GGBS on the strength of geo-polymer concrete. In order to study the tensile strength of concrete having
Recycled Concrete Aggregates or Crushed Concrete Aggregates are Manufactured from Demolished Concrete by Concrete Recycling Process.
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 ...
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.

Among the nine different combination the maximum compressive strength of concrete is achieved by using AL10% and GGBS 30% is 38.08 N/mm 2 . C60A10G30 is 28.76% higher than the control mix. Result shows that concrete incorporating alccofine and
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.
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

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 ...
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.

Concrete's long life means that is more likely that a concrete building will come to the end of its life because no further use can be found for it, rather than a case of the concrete having failed due to age. In these cases, demolition is not always the automatic course.
This paper investigates workability and strength of concrete made with different proportions of waste paper sludge ash (WSA) and ground granulated blast-furnace slag (GGBS) as binder, at two w/b rations: 0,5 and 0,4. Specimens were tested unconfined
In major Egyptian cities there is a surge in construction and demolition waste (CDW) quantities causing an adverse effect on the environment. The use of such waste as recycled aggregate in concrete can be useful for both environmental and economical aspects in the construction industry.
