(Civil Engineering, RIMTIET/PTU, INDIA) 2(Civil Engineering, RIMTIET/PTU, INDIA) ABSTRACT : In this paper, we have studied that the compressive strength of hardened concrete made ... absorption and concluded that recycled coarse aggregates have am in or effect on ...
Construction aggregate, or simply "aggregate", is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, and recycled concrete. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material.
be reached using recycled aggregate as a coarse material. Using more than 35% of fine recycled aggregate causes an obvious weakness in the concrete strength.[6] 5. Concrete made with recycled aggregates has a compressive strength about 22%32% less than the strength of the concrete made with natural aggregates. [7] III.
crushed bricks to substitute the coarse aggregate (gravel) in concrete. Two types of ... Key words: Recycled aggregate, Crushed bricks, Light weight concrete, Demolition waste. ... used in parts of India and Bangladesh for concrete making and the ...
The compressive strength of recycled aggregate concrete tends to be lower than that of aggregate concrete at low w/c ratios. At higher w/c ratios, the compressive strength of recycled aggregate concrete is similar to that of aggregate concrete. Jeong [7] used concrete structures at Chicago's O'Hare Airport to study recycled coarse aggregate.
Development of sustainable construction material using construction and demolition waste ... drying shrinkage strain increased with recycled coarse aggregate In the study carried out to ... Currently in India, similar to most Asian countries
This paper presents the experimental results of recycled coarse aggregate concrete and results are compared with the natural crushed aggregate concrete. The fine aggregate used in the concrete, recycled and conventional is 100 percent natural. ... (1998), "Future of Recycled Aggregate Concrete in India," National Seminar on New Materials ...
At this rate of use, there will be a critical shortage of NA in the future unless an alternative material for natural coarse aggregate is used. One source for alternative aggregate is recycled concrete aggregate (RCA) from construction and demolition waste.
Abstract—By far the most common coarse aggregate used in concrete is obtained from natural rock, but type of rock suitable for concrete making is not available everywhere. In Tripura a northeastern state of India brick aggregate concrete are used conventionally for ordinary concrete due to scarcity of aggregate from natural source.

Coarse Aggregate . Locally available coarse aggregates were used in this work. Aggregates passing through 12mm sieve and retained on 10mm sieve were sieved and tested as per Indian standard specification IS: . Ceramic Waste . The principle waste coming from .
2) The long term strength development of recycled coarse aggregate concrete is more favourable than natural aggregate concrete. 3) The durability performance of recycled concrete is affected by the higher absorption and porosity of Recycled Coarse Aggregate. 4) The optimum percentage replacement of recycled aggregate is 40%.
able concrete; treated recycled concrete aggregate. INTRODUCTION Concrete has been one of the main construction materials for more than a century. Fine and coarse aggregates generally occupy 60 to 75% of the concrete volume. The global consumption of natural aggregate (NA) is estimated to be 9 to 10 billion tonnes (10 to 11 billion tons) each year.
