Recycled aggregate samples collected from a southeastern Australia centralised recycling plant was adopted for the production of concrete. Particle size distribution is of importance as it affects workability and strength (Neville 1995).As
However, as shown in Chapter 5, there is a greater probability of recycled masonry aggregates (RMAs) showing higher water absorption capacity compared with RCA and

In Japan, recycled concrete aggregate (RCA) and recycledaggregate concrete (RAC) are standardized in the Japanese Industrial Standards (JIS) A
Olorunsogo and Padayachee (2002) studied the performance of RAC examined by durability indexes. RAC mixes were prepared by replacing NA with 0%,
The present paper discusses the various possible recycled aggregates used in concrete production, their effect on both fresh and
Feasibility and performance analysis of carbonated recycled aggregate concrete. Manpreet Singh, A. Danie Roy, S. Waseem, Harsimranjit Singh. Materials
Fifty percent of the total weight of construction and demolition waste is concrete. Consequently, the utilisation of crushed waste concrete must be considered as
There is a growing need to find ways to reuse fine concrete waste from the construction industry. In this study, recycled concrete fines were granulated and used as
Electric arc furnace (EAF) slag is a byproduct of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil
摘要： In this study recycled coarse aggregates obtained by crushed concrete were used for concrete production. Four different recycled aggregate concretes were produced; made
This paper discusses the properties of RCA, the effects of RCA use on concrete material properties, and the large scale impact of RCA on structural members. The review study yielded the following findings in regards to concrete material properties: (1) replacing NA in concrete with RCA decreases the compressive strength, but yields
Concrete is the most used manmade material in the world since its invention. The widespread use of this material has led to continuous developments such as ultrahigh strength concrete and selfcompacting concrete.
Nowadays, nearly one ton of concrete is produced each year for every human being in the world on average. On one hand, the use of recycled materials in cement and concrete production helps to reduce raw materials and urban land occupation. However, on the other hand, the recycled materials used as partial replacement of raw materials
Fifty percent of the total weight of construction and demolition waste is concrete. Consequently, the utilisation of crushed waste concrete must be considered as imperative in concrete production

Construction and demolition ( C&D ) trash is a significant part of the solid waste stream, accounting for around 25 % of total solid waste in the United States.; Concrete makes up the majority of C&D
Description. New Trends in Ecoefficient and Recycled Concrete describes different recycled materials that have been used in ecoefficient concrete, reviewing previous publications to identify the most
Mirza and Saif3 have studied the effect of silica fume on recycled aggregate concrete characteristics. The percentages of recycled aggregate replacements of natural aggregate used by weight were 0, 50, and 100%, whereas the percentages of silica fume replacements of cement used by weight were 5, 10, and 15%. The results.
Introduction. In the last decade, global warming has become more intense due to carbon dioxide (CO 2) emissions from industrial plants.In particular, cement industry emits a large amount of carbon dioxide, in which approximately 1 tonne of cement production releases almost 1 tonne of CO 2 [1]. According to the report of the United Nations, global
Disadvantages of Recycled Aggregate. Downgrading of quality of concrete. Increase in water absorption capacity ranging from 3% to 9%. Decrease in compressive strength of concrete (1030%) Reduces
Firstly, the book presents key findings on the micro and mesostructure of recycled aggregate concrete (RAC), while the second part focuses on the mechanical properties of RAC: the strength, elastic modulus, Poisson’s ratio, stressstrain curve, etc. The third part of the book explores research on the durability of RAC: carbonization
Recycled aggregate samples collected from a southeastern Australia centralised recycling plant was adopted for the production of concrete. Particle size distribution is of importance as it affects workability and strength (Neville 1995).As regards the sample collected was fulfilling the particle size distribution of 10 mm and 20 mm
The present paper discusses the various possible recycled aggregates used in concrete production, their effect on both fresh and hardened properties as well as durability performances. The
Replacing natural aggregate concrete with recycled one in the highrise structure resulted in about a 2.175 × 10 5 kg C e decrease in carbon footprint. Another research [100], confirmed that
4.1.1. Bulk Density. The bulk densities of the RCA and the NCA were determined in compacted and loose conditions. The compacted bulk density for the RCA was 1344 kg/m 3, whereas that for the NCA was 1678 kg/m 3.The loose bulk densities for the RCA and the NCA were 1178 kg/m 3 and 1567 kg/m 3, respectively.It can be noticed
The effects of SBR Latex dosages on compressive strength are mentioned in Table 7, which indicate that as the SBR Latex dosage increases from 1 to 2%, the compressive strength for 14 days and 28

Electric arc furnace (EAF) slag is a byproduct of steel production in electric arc furnaces. Several studies have tried to demonstrate its suitability in civil engineering application, such as in bituminous mixtures and cementbased materials, due to its good physical, chemical and mineralogical properties. Particularly the reuse as
