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.

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-

Using crushed stone dust as a substitute for fine aggregates in concrete

Caderno Pedagógico
Generation 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 ...

Influence of the partial substitution of fine aggregate by granite powder in mortar on the process of natural carbonation

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2019
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 planning matrix of ...
