Economic viability analysis of recycling waste plastic as aggregates in green sustainable concrete.

Waste Management, 2023
Plastic waste management is one of the major global challenges at present. Recycling single used plastic waste as partial replacement of natural aggregates in concrete may reduce problems regarding mismanagement of plastic waste and unsustainable ...

Properties of concretes produced with waste concrete aggregate

Cement and Concrete Research, 2004
Abstract An environmentally friendly approach to the disposal of waste materials, a difficult issue to cope with in today's world, would only be possible through a useful recycling process. For this reason, we suggest that clearing the debris from destroyed buildings in such a way as to obtain waste concrete aggregates (WCA) to be reused in concrete ...

Concrete with ceramic waste aggregate

Cement and Concrete Composites, 2005
Use of hazardous industrial wastes in concrete-making will lead to greener environment. In ceramic industry about 30% production goes as waste, which is not recycled at present. In this study an attempt has been made to find the suitability of the ceramic industrial wastes as a possible substitute for conventional crushed stone coarse aggregate ...

Waste tire fiber modified concrete

Composites Part B: Engineering, 2004
Abstract It is well known that waste tire chip modified concrete has very high toughness. However, its strength and stiffness are reduced significantly. Sometimes, the strength and stiffness are so low that the modified concrete cannot be used as structural materials.

Sustainable concrete waste recycling

Proceedings of the Institution of Civil Engineers - Construction Materials, 2008
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. It is essential to reuse such construction waste from a life-cycle assessment (LCA) perspective and for effective recycling of construction resources.

Waste management strategies for concrete

Environmental Engineering and Policy, 2001
Recycling and reuse of waste such as building rubble, concrete lumps, etc. generated at construction and demolition sites form part of a wider, complex issue, primarily relating to improving supplies of construction material and solving problems of disposal of waste construction material.

Concrete waste recycling technology

Stroitel nye Materialy
In Russia, as a result of the dismantling and demolition of buildings and structures, more than 15 million tons of construction waste are generated annually, and their number is growing annually. It is necessary to search for technical solutions and technologies for the use of concrete scrap in new composite materials.It is proposed to pre-process ...

ECO-FRIENDLY CONCRETE FROM WASTES

Environmental Engineering and Management Journal, 2017
The paper presents the experimental results obtained on cement concrete with different types of waste and the analysis of their effects on density, compressive strength, flexural strength and splitting tensile strength. The tests results were compared with a control mix without aggregate substitution.

Using waste concrete as aggregate

Cement and Concrete Research, 1995
Abstract 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.
