15/11/2014 Classification properties of recycle aggregate concrete Material composition is the basis for classification of recycled concrete aggregate in two main types- 1) Crushed concrete 2) Mixed material Each of these types is divided in a class for bound and a class for unbound use Crushin g age Bulk specific gravity Bulk density Absorp tion (%) Crushin g value(% ) 1 days Coarse Mediu m Fine
14/03/2015 The use of recycled concrete aggregate is proved to be a valuable, buildings materials in technical, environmental economical respects. Recycle reuse is an appropriate solution to problems of dumping hundred of thousands of tons of demolition wastes. However,more research and initiation of pilot project for application of RCA is started for modifying our design codes, specifications ...

to as recycled aggregate concrete, or simply, RAC. The goal is to identify if RAC has achieved similar mechanical performances as normally expected from conventional con-crete. Considerable amount of research has been carried out with different types of materials. This thesis presents the most widely researched waste material used as RA, that is, concrete waste. In addition, other less ...
Recycled concrete aggregate (RCA) is the designation used in BS 8500-2 for recycled aggregate principally comprising crushed concrete. Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concrete. This is largely due to the potential for higher proportions of the masonry ...
Recycled aggregate concrete (RAC) is produced in three major steps: Evaluation of Source concrete: The first step in production of RAC is to determine the quality of the source concrete. Properties and records of source concrete like strength, durability and composition are looked into for deciding the proper source concrete. Crushing of demolished concrete: The simple process involves ...

Download as PPT. Submit Your Project/Presentation. Objectives of the Project . To compare the compressive strength of Recycled Coarse Aggregate for Constructional Concrete with the Conventional concrete. To know its applications in the construction industry. To reduce the pressure on naturally available materials by replacing it with recycled aggregate. To compare the physical characteristics ...
the recycled aggregate concrete is almost 85% and 80% of natural aggregate concrete. Amn on.et.al (2002), concrete having a 28 -day compressive strength of 28 MPa was crushed at ages 1, 3 and 28 days to serve as a source of aggregate for new concrete, simulating the situation prevailing in precast concrete plants. The properties of the recycled aggregate and of the new concrete made from it ...
Keywords: recycled aggregate concrete, construction and demolition waste, concre-te properties, research. 1. INTRODUCTION Recent floods, that struck our our country and the region, have caused widespread damage, among which damage to building structures is dominant. Society is not only faced with the problems of fin- ding solutions for the construction, reconstruction and repair of buildings ...
recycling concrete aggregate (RCA) a preferred option. The use of RCA to conserves natural aggregate IJERT the associated environmental cost of exploration transportation waste minimization reducing the burden on landfills is a global issue. Extensive research has been carried out worldwide on the use of recycled aggregate in concrete. It also shows that globally the concrete construction ...
The results of recycled concrete aggregate testing are shown in Table 2 and grading curves in Figure 5. Properties of natural and recycled concrete aggregate were tested according to Serbian standards for natural aggregates and quality requirements given in Tables 1 and 2 are also according to Serbian standard for natural aggregates: SRPS B.B2.010:1986 [22]. As it can be seen from Table 2 ...

a cement- stabilized pavement base course material consisting of recycled concrete aggregate, ASTM Class C fly ash, and waste plastic (high- density poly ethylene) strips obtained from post - consumer water and milk containers. The primary focus of the study was to systematical ly characterize the new composite base course under both static and dynamic (fatigue) loading conditions to gain some ...
The extensive research on recycled concrete aggregate and recycled aggregate concrete (RAC) as started from year 1945 in various part of the world after second world war, but in a fragmented manner. First effort has been made by Nixon in 1977 who complied all the work on recycled aggregate carried out between 1945-1977 and prepared a state-of-the-art report on it for RILEM technical committee ...
