Properties and durability of concrete with olive waste ash as a partial cement replacement

Advances in concrete construction, 2021
This research aims to study the utilization of olive waste ash (OWA) in the production of concrete as a partial substitute for cement. Effects of using OWA on the physical and mechanical properties of concrete mixtures have been investigated. This is done by carrying out tests involving the addition of various percentages of OWA to cement (0%, 5%, 10 ...

Use of Biomass Ash in Reinforced Clayey Soil: A Multiscale Analysis of Solid-State Reactions

Recycling, 2022
Clayey soils are treated with binding agents to improve their mechanical properties, as these soils are widely used in construction. The production of binding agents is an energy-intensive process and emits significant amounts of CO2.

Effect of olive waste ash on properties of asphalt cement and asphalt concrete mixtures

International Journal of Pavement Research and Technology, 2020
In this study, the effect of olive waste ash on the properties of asphalt cement and asphalt concrete mixtures was investigated. Asphalt cement with (80/100), limestone and valley gravel aggregates, and olive waste ash were used. Five asphalt binder levels with (0, 5, 15, and 20) percentages of olive waste ash (OWA) by volume of asphalt-ash binder were

Optimisation of hybrid eco-efficient mortars with aggregates from construction and demolition waste and olive biomass ash

Construction and Building Materials, 2023
Materials considered as waste, such as Construction and Demolition Wastes (C&DW) and Biomass Bottom Ash (BBA) are the subject of this study to implement them in cement-based materials. After basic and advanced characterization, as well as leaching studies to assess the environmental impact, they are implemented in mortars as a replacement for standard ...

Characterization of biomass ashes produced at different temperatures from olive-oil-industry and greenhouse vegetable wastes [PDF]

Fuel, 2017
Reuse and recycling of biomass ashes as new resources can boost the development of a circular and sustainable economy. This requires knowledge concerning the characteristics and properties of the ash for different applications. In this study, novel biomass ashes from combustion, at different temperatures, of olive-oil wastes and from the gasification ...
