Recycling of Demolished Concrete and E-waste S.P.Kale1, H.I.Pathan2 1, 2Assistant Professor, Civil Engineering Department, SMSMPITR Akluj, India Abstract: Concrete is the most widely used construction material all over the world in view of its compressive strength, high mouldabilty, structural stability and economic considerations.
May 14, 2015 · This paper discusses the suitability of producing concrete with 100 % recycled aggregate to meet durability and strength requirements for different applications. Aggregate strength, gradation, absorption, specific gravity, shape and texture are some of the physical and mechanical characteristics that contribute to the strength and durability of concrete. In general, the quality of ...

Core samples for demolished concrete were tested to determine its compressive strength. The core test results can be thought of as aggregate properties for the new concrete. Then, the compressive strength and splitting tensile strength of the new recycled aggregate concrete (RAC) were determined experimentally by casting a cubes and cylinders, respectively.
The natural coarse aggregates (NA) used were granite and the properties were reported in Table 1.The recycled coarse aggregates (RA) used in this study were the crushed waste concrete with a strength of 20–30 MPa from demolished civil buildings. The properties ...

Mechanical properties of concrete made with 30% of SBA and 30% of construction waste were similar to the reference concrete. Joint application of SBA and construction waste achieved 93% of compressive strength.

compressive strength for concrete is observed for mixes up to 40% GGBS at all ages. Even for concrete with 50% GGBS, the strength was equal to that of control concrete at 56 days. Figure 3 Compressi ve Strength Vs Age of Concrete Up to 50% replacement, concrete with GGBS generally achieved strengths similar to control concrete till 28 days and after 28 days it exceeded the strength of control concrete.
The increased quest for sustainable and eco-friendly materials in the construction industry has led to research on partial replacement of the conventional constituents of concrete by two selected waste materials. The broad aim of this work was to investigate the ...

Pavement Quality Concrete (PQC) is that concrete which is used for highway and road construction .Due to high strength, better serviceability and economy. Now a day's engineers are much focused on development of pavement which could be effective
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.
Waste plastic mix concrete with and without superplasticizer was tested at room temperature. Forty-eight cube samples were moulded for compressive strength tests at three, seven, and twenty-eight days. Eight beams were also cast to study the flexural

strength to an extent of 20% and 30% respectively with respect to control concrete. The tensile strength and flexural strength also followed the same order. At the later age (90 days) the ternary blended admixed concrete with 50% recycled aggregate attained 80% strength of the control concrete. Hence it is concluded that these waste materials can
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 ...

Due to exponential growing in urbanization and industrialization, byproducts from industries are becoming an increasing concern for recycling and waste management. Ground granulated blast furnace slag (GGBS) is by-product from the blast-furnaces of iron and steel industries. GGBS is very useful in the design and development of high-quality cement paste/mortar and concrete. This paper covers ...
