The developers, AET and Cemstone, wanted to design a strong concrete mix that was made from as much recycled material as possible. By analyzing the recycled concrete aggregate through a microscope, they learned there is always unhydrated cement available to form cement paste in the new "green" concrete mix.
May 22, 2018· Concrete mix design is the process of selecting the ingredients for a concrete mixture and deciding on their proportions. When designing a concrete mix, you should always consider the desired strength, durability, and workability of the concrete for the project in question.
Strength and durability of the recycled aggregate. Some experiments showed that recycled aggregate doesn't have good durability like the natural coarse aggregate but the durability can be improved by mixing it with special materials such as fly ash to produce high strength and durable concrete.
Shear strength of recycled aggregate concrete is lesser than of normal concrete. This is because the recycled aggregate from field-demolished concrete for example can be relatively weaker than a typical natural aggregate. In general, there is a 10% decrease in strength when recycled coarse aggregates are used. ... They design mostly the looks

As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including quarry, aggregate, and different kinds of minerals.
Jan 01, 1983· Compressive strength of hardened concretes made from recycled concrete coarse aggregates was studied as a function Of the compressive strength of original concretes from which the coarse aggregates were derived Also studied were properties of fresh concretes made from recycled aggregates, gradings of crusher products, properties of recycled ...
Nov 15, 2014· It is called recycled aggregate which can be produced by concrete crusher. The aggregates are categorized by size as coarse and fine aggregate. The characteristic of recycled aggregates could be different by its parent concrete because the parent concrete was designed for its purposes such as permeable, durable and high strength concrete
Aug 26, 2014· This work is devoted to the study of fresh and hardened properties of concrete containing recycled gravel. Four formulations were studied, the concrete of reference and three concretes containing recycled gravel with 30, 65 and 100 % replacement ratios. All materials were formulated on the basis of S4 class of flowability and a target C35 class of compressive strength …
By combining various recycled materials such as Fly-Ash and Quarry Dust we provide Concrete Sand to the Building Industry that is more cost effective, and environmentally friendly, at the fraction of the cost without compromising the strength and work-ability of the concrete.

Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete. The recycled concrete aggregates have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates.
The RCA concrete mixes were found to possess bulk engineering and durability properties similar to the corresponding natural aggregate concretes, providing they were design to have equal strength. 2.2 RECYCLED CONCRETE AS COARSE AGGREGATE IN CONCRETE
May 14, 2015· Evaluation of physical and mechanical properties of RA: absorption, aggregate texture (type of crushers, number of crushing stages), aggregate size and gradation, specific gravity, density, mortar content, percentage and type of contamination, aggregate strength and abrasion resistance are the main properties that affect utilizing RA in concrete production.
In general, the reuse and recycle of construction waste is concentrated in the preparation of recycled aggregate for concrete. By adding a portion of recycled aggregate instead of natural aggregate coarse into the mixture, producing the recycled concrete, which can conserve energy and materials for concrete production. Strength and durability ...
