Recycled Aggregates () — Construction materials are increasingly judged by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or pavement subbase layers.
performance of concrete wall panels for residential construction, specifically precast basement wall panels produced by Kistner Concrete Products, East Pembroke, NY. The second application was the development of a concrete mix design comprising both recycled glass and carpet fibers for precast concrete façade elements with architectural finishes.

The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
This experimental work investigates the impact of substituting part of the conventional aggregates with rubber aggregates on certain characteristics of the cement concretes. This incorporation of rubber aggregates resulting from cutting worn tires in practical sizes decreases the mechanical resistances of the concretes while improving slightly the fluidity of the tested mixtures.
Construction materials are increasingly judged by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or other applications.
ABSTRACT. This study presents the effects of recycled concrete aggregate (RCA) on the key fresh and hardened properties of concrete. RCA was used to produce highworkability concrete substituting 0 natural coarse aggregate (NCA) by weight.
379 a review on mechanical characteristics of normal concrete partially replaced with recycled ceramics aggregates b. j. odero, r. n. mutuku and c. k. kabubo
Recycled crushed concrete may be subjected to various natural or mechanical forces that produce small particles (dust) which may contain respirable crystalline silica (particles less than 10 micrometers in aerodynamic diameter).
It was found that the statistical characteristics of the compressive strength of recycled aggregate concrete do not differ very much from those of normal concrete (NC) with similar strength, irrespective of the recycled coarse aggregate replacement percentage.

Characteristics of the waste being added to the concrete, such as the type of plastic and the size and shape of the particles can all have an influence on the final concrete properties.
Characteristics of mortar and concrete containing fine aggregate manufactured from recycled waste polyethylene terephthalate bottles Construction and Building Materials ABSTRACT This paper presents the development of lightweight aggregate concrete using fine aggregate that is manufactured from recycled waste polyethylene terephthalate (PET) bottles.

Characteristics of mortar and concrete containing fine aggregate manufactured from recycled waste polyethylene terephthalate bottles ... In this study, waste PET bottles have been recycled for use as an aggregate for concrete. To do this, lightweight aggregate have been formed consisting of waste PET bottles (WPLA) coated with
recycled waste tire particles' usage expanded into a relatively new product called rubberized concrete. Rubberized concrete uses portland cement as its binder.
This study aims to evaluate the fundamental characteristics of concrete using recycled concrete aggregate (RCA) that was recycled through advanced recycling process.
practice of recycling of demolished concrete for use in sub grades has already been set up. However a new concrete that is produced with such a recycled concrete seems to have higher porosity, lower strength and modulus of elasticity when compared to normal conventional concrete.
The author is also intrested in the recycled concrete aggregates and their use in concrete and mortar along with byproduct materials including silica fume and ground granulated plast furnace slag. He is working now on the properties of the contaminated recycled aggregate concrete.
