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 ...

Using crushed stone dust as a substitute for fine aggregates in concrete
Caderno PedagógicoGeneration of waste from mining and high consumption of natural aggregates resulting from civil construction works have significant economic and environmental impacts. Aiming to use the stone dust residue from the rock crushing process, this study experimentally evaluates the use of crushed stone dust as a partial substitute for fine aggregates in ...

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

Evaluation of durability of concrete substituted heavyweight waste glass as fine aggregate
Construction and Building Materials, 2018Abstract 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.

Activated alumina sludge as partial substitute for fine aggregates in brick making
Construction and Building Materials, 2019Abstract 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-

This article presents an evaluation of the influence on the natural carbonation process of the use of granite cutting residue as a replacement for fine aggregate in mortars. The methodology adopted consisted of replacing the fine aggregate with granite cutting residue, analysing the carbonation depth with the aid of an experimental
