Substitution potential of plastic fine aggregate in concrete for sustainable production

Structures, 2022
Abstract This study evaluates the mechanical and durability characteristics of eco-friendly concrete incorporating electronic plastic waste (EPW) as partial replacement of fine aggregate. This strategy not only reduces the adverse impacts of EPW on the natural environment but also prevents the depletion of natural resources due to excessive quarrying.

Utilization of cold bonded fly ash lightweight fine aggregates as a partial substitution of natural fine aggregate in self-compacting mortars

Construction and Building Materials, 2015
Abstract In this study, lightweight fly ash fine aggregates (LWFAs) were used as a partial replacement of natural fine aggregate to investigate the fresh and hardened states of self-compacting mortars (SCMs). For this, a powder mixture of 90% fly ash (FA) and 10% Portland cement (PC) by weight were pelletized in a tilted pan through a cold-bonded ...

Evaluation of durability of concrete substituted heavyweight waste glass as fine aggregate

Construction and Building Materials, 2018
Abstract Concrete is the most widely used construction material, and huge amounts of natural resources are required to manufacture it. With relatively recent rapid industrial development as well as the improvement of people’s living standards, the volume of domestic and industrial waste is increasing, and much of this waste is not recycled.

Properties of concrete containing jarosite as a partial substitute for fine aggregate

Journal of Cleaner Production, 2016
Abstract A series of laboratory investigations were undertaken to evaluate the performance of concrete mixtures incorporating jarosite as partial replacement of fine aggregates. The effect of jarosite on the mechanical properties and durability has been investigated.

Activated alumina sludge as partial substitute for fine aggregates in brick making

Construction and Building Materials, 2019
Abstract Community water defluoridation plants primarily use activated alumina (AA) for treatment. However, this process generates toxic AA-sludge for which no sustainable method of disposal is currently known. This study evaluated whether AA-sludge could be partially used in manufacturing bricks that are structurally stable and non-polluting. The AA-

DEVELOPMENT OF SUSTAINABLE CONCRETE USING COPPER SLAG AS A SUBSTITUTE OF FINE AGGREGATE

2023
Abstract The research aimed to investigate the mechanical and durability qualities of concrete mix designs by incorporating copper slag (CS) as a substitute for fine aggregate of natural sand (NS). Eleven concrete mixtures were casted, including the control mix, with varying concentrations of CS ranging from 0% to 100% at an increment of 10%.

Properties of Concrete Using Copper Slag as a Substitute for Fine Aggregate

"SP-114: Fly Ash, Silica Fume, Slag, and Natural Pozzolans in Concrete: Proceedings of the Third International Conference", 1989
This paper will discuss that copper slag, a by-product of copper production, contains large amounts of iron oxide and silicate. It is chemically stable and its physical properties are similar to that of natural sand. The physical and chemical properties of copper slag were investigated.

Spent fluorescent lamp glass as a substitute for fine aggregate in cement mortar

Journal of Cleaner Production, 2017
Abstract In recent years, recycled waste materials have been widely used to produce construction materials in an effort to reduce the utilization of natural resources and post-consumer wastes entering landfills. In this paper, the results of an experimental programme on studying the feasible use of spent fluorescent glass (FG) as a fine aggregate ...

Use of waste tire rubber as a fine aggregate substitute in concrete

Caderno Pedagógico
The civil construction sector significantly contributes to economic growth but also heavily exploits natural resources, raising sustainability concerns. This study investigates the incorporation of waste tire rubber as a partial substitute for fine aggregate in plain concrete to promote environmentally friendly construction practices.
