Recycled Concrete–A Sustainable Choice

Nov 27, 2012· The specific gravity of the natural aggregate was 2.65 and that for recycled concrete aggregate was 2.19 and 2.04 for 20 and 13 mm maximum size recycled concrete aggregate, respectively. The water absorption for 20 and 13 mm recycled concrete aggregates was 5.3 and 8.2 %, respectively, compared to 1.0 % for the natural aggregate.

Mechanical and fracture properties of recycled aggregate ...

Recycled concrete aggregates (RCAs) offer a sustainable solution to the multifarious exigent crises involving the ever-increasing demand of aggregates and the disposal of construction and demolition waste arising from demolishing non-serviceable infrastructure. However, the use of RCA in concrete is mostly limited to non-structural purposes at a limited replacement proportion of the ...

Recycled Concrete–A Sustainable Choice

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.

Recycled Concrete Aggregate

concrete. 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-

Mechanical and fracture properties of recycled aggregate concrete in design codes and empirical models. Elhem Ghorbel. Corresponding Author. E-mail address: elhem.ghorbel@u-cergy.fr. ... In this paper the relationships between the mechanical and fracture properties of recycled aggregate concretes (RAC) are investigated based on the own research ...

Mix design procedure for recycled aggregate concrete

Keywords— Recycled Aggregate, Recycled Concrete, Compressive Strength . I. INTRODUCTION. HE environmental impact of producing raw ingredients of concrete (such as coarse aggregate, fine aggregate and concrete) is considerable [1-4]. Many structures created with reinforced concrete are reaching the end of their design life.

At Pece of Mind Environmental, Inc., we do more than just take down structures. We always look for ways to lessen the environmental impact of demolition and new construction, while helping our clients save money. One of the ways that we do this is by reprocessing waste and demolition concrete into recycled aggregates.

EUROCODE 2-BASED STRUCTURAL DESIGN OF A REINFORCED RECYCLED AGGREGATE CONCRETE SLAB R V Silva1, J de Brito1 1. CERIS, Instituto Superior Técnico, Universidade de Lisboa, Lisboa, Portugal ABSTRACT. This paper presents the design of a reinforced recycled aggregate concrete slab in conformity with Eurocode 2.

Mix design procedure for recycled aggregate concrete

Fig: Process of Waste Concrete Recycling. Quality of recycled aggregate and its concrete: The strength of recycled aggregate concrete is about 10 to 15 per cent less as compared to concrete with fresh aggregate. However suitable mix designs may be made and reliable results obtained.

Investigation of Mechanical Properties of Recycled ...

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.

PROPERTIES OF RECYCLED AGGREGATE CONCRETE

Thus, the use of Fine Recycled Concrete Aggregate (FRCA) is becoming increasingly important, as this fine fraction is generated in large quantities when recycled coarse aggregates are produced. The majority of literature data relate the inferior quality of recycled concrete to the recycled concrete aggregate (RCA) porosity and, consequently ...

Mechanical and fracture properties of recycled aggregate ...

Replacement of natural aggregates by concrete road recycled aggregates in the mix design of concrete is a solution to decrease nature depletion. Natural concrete slabs were cured in water, sea water, chloride solutions or sulphate solutions and then crushed to obtain and contaminated (polluted) recycled aggregates.
