When restrictions severely limit local access to concrete aggregate, broken pieces of waste concrete (WCA) are used as aggregate. Today environmental studies discussing the recycling and reuse of waste materials are gaining great importance. Using waste material which was obtained from razed buildings ...

Concrete is the most widespread construction material, as a result of its production, natural sources are running out, and also natural environment is being disturbed. In addition, building wastes brought about by the renovation activities for the structures that have expired. In order to maintain ...
This paper reviews some of the agro-waste materials, which are used as a partial replacement of fine aggregate in concrete. Different properties of fresh and hardened concrete, their durability and thermal conductivity when admixed with agro-wastes are reviewed. Agro-waste used in self-compacting ...
PROBLEM TO BE SOLVED: To provide a method to manufacture spherical polished concrete aggregates with rounded profile and lowered water absorption, the use of which as aggregate for concrete can improve the solid volume percentage and reduce the unit water content. SOLUTION: The method comprises the...
Among the construction waste that could be recycled, we can mention the aggregates resulting from crushed concrete. While the acquired knowledge about the use of recycled aggregates in new concrete mixes is fairly large, the use of such aggregates in the production of concrete blocks is very li...
A preliminary study has been conducted to evaluate thefeasibility of using recycled concrete aggregate (RCA) inself-compacting concrete (SCC). Two different sources of RCA werecollected and used in proportioning SCC with different levels ofreplacement of natural aggregate. Physical properties such asspe...
Massive volumes of construction waste will be generated by the demolition of older structures such as power stations that were built more than 30 years ago... Y. Dosho D. - 《Construction Materials》 被引量: 8发表: 2008年 Utilization of fine concrete waste as a lightweight aggregate via gr...
Development of self-foaming cold-bonded lightweight aggregates from waste glass powder and incineration bottom ash for lightweight concrete To address the scarcity of natural aggregates and reduce the energy consumption of the concrete industry, a selffoaminggeopolymer cold-bonded lightweight a...

An asphalt mixture containing recycled aggregate is provided to optimize the amount of asphalt binder used according to the kinds of waste concrete and to optimize the function of the asphalt mixture to fit construction standards. An asphalt mixture is composed of recycled aggregate including 2-6wt...
