Thus, the main objective of this research was to analyze the technical feasibility of using recycled aggregates "Class A" mixed with hydrated lime to construct pavement layers (base and sub-base) with low traffic volume. Therefore, materials were subjected to physical characterizing tests as well as mechanical performance tests.

The main objective of the present investigation is to evaluate the suitability of recycled concrete aggregate, recycled e-waste and coconut shells as a coarse aggregate in concrete. This investigation target to determine the optimum percentage of all these

Using recycled concrete from demolished buildings as an aggregate in new concrete preparation can have a significant role in the sustainable development of the concrete industry; therefore, in this research work, the effect of employing different percentages (i.e., 20, 40, 60, 80 and ) of recycled concrete aggregates and the impact of using ...

the base course composite consisted of waste or recycled materials. It was found that a mixture containing only 4% cement, 4% fly ash, and 92% recycled aggregate (by weight) achieved a compressive strength of about 5 MP a (725 psi), a split tensile strength of about 0.75 MPa (109

aiming to produce recycled aggregates with physical-mechanical characteristics suitable for use in rigid pavement construction. Recycled aggregates under investigation are obtained by crushing of cement concrete from the demolition of buildings in Iaşi municipality. The main objective …

The main objective of this study is to examine the effect of recycled coarse aggregates (RCAs) used as alternative granular in fills in hollow facing column. As granular in fills, two types of recycled aggregates were

Chapter 3 presents the material tested in this thesis. Chapter 4 describes the theory behind the tests and how they were conducted. Chapter 5 outlines the

In the second category, specimens were strengthened using CJs and tested. Since the evaluation of the behaviour of jacketed recycled aggregates concrete beams was the main objective here, CRA were used in both original beams and jackets at two replacement contents of 0% and .

brick as a coarse aggregate to produce recycle concrete. The fine aggregate of natural siliceous sand. Its characteristics satisfy the 2. Research Significance 2003]. It was clean and nearly free from impurities with The main objective of this research is to establish the performance of recycle clay brick as a coarse aggregate to produce ...

The main objective of this report is to promote concrete recycling as an issue and encourage thinking in this area. It provides some discussion of key issues without going into signifi cant technical details. The report ultimately promotes a goal of "zero landfi ll" of concrete. …

The main objective of this study was utilization of marble, granite and recycled aggregate waste with polypropylene fiber as a replacement for conventional natural coarse aggregates in concrete. Experimental investigations were carried out to examine the feasibility of use of marble, granite and recycled aggregates waste as coarse aggregates in ...

Also suggested that recycled aggregate can be used as bulk fill, sub base material in road construction, playground, canal lining and for preparation of new concrete. 2.3Use of Recycled Aggregate as a Replacement of Natural Aggregate and Its effect on Properties M. Etxeberria (2007) studied recycled coarse aggregates

Aggregates are the most mined material in the world. Construction aggregate is a broad category of granular raw material of different sizes (sand, gravel, crushed stone, slag, recycled concrete etc) used in construction. Aggregate can be used in a number of ways in construction. In roads and railway ballast the aggregates are used to resist the overall (static as well as

the waste materials for different purpose for its proper use of disposal. The main objective is to encourage the reuse of waste in construction sector. In many countries recycling techniques have been made since 1970.For example the reuse of concrete and building masonry for the preparation of base course for road in Netherland.

percentages of coarse recycled concrete aggregate. The main objective was to study suitability and effect of coarse recycled aggregate in new generation concretes. In the recent years the de mand for construction materials has grown tremendously, so has the amount of construction and demolition waste, putting huge pressure on the environment.

This review focuses on structural RC made with coarse recycled aggregate from concrete waste. The main objective is to provide a state of the art report on RC's properties and an analysis on how to predict them taking into account relevant research works.

So, the main objective of this study is to review the overall aspects of recycled concrete aggregate. And Tang et al. (2017) [3] ... The removal of impurities and crushing are the main recycling process of recycled aggregate. An investigation showed that the size of 10 mm and 14 mm RA can give more strength in hardened recycled concrete with ...
