Utilisation of olive waste ash in mortar mixes

Structural Concrete, 2010
Huge amounts of olive waste residues are accumulated every year in olive-oil-producing countries, making an environmental impact. This study investigates the utilisation of olive waste ash in mortar mixes to reduce the environmental pollution arising from olive waste residue. Three olive waste ash levels were considered in the study: 5, 10 and 15%. The

Effect of Olive Waste Ash on the Properties of High-Strength Geopolymer Concrete

Structural Concrete
Abstract This study examines the effect of incorporating olive waste ash (OWA) into high‐strength geopolymer concrete (HSGC) by partially replacing fly ash (FA) and/or granulated blast furnace slag (GBFS) in the presence of rice husk ash (RHA). A total of 18 different mixtures were prepared and divided into three groups: (1) Utilizing

Performance of Olive Waste Ash Concrete Exposed to Thermal Cycling

Journal of ASTM International, 2010
Abstract This paper explores the influence of olive waste ash (OWA) on the performance of concrete to thermal cycling. The performance of concrete to thermal cycling was evaluated by measuring the compressive strength, electrical conductance, and visual inspection of cracks in concrete specimens.

Performance of Olive Waste Ash Concrete Exposed to Alkali-Silica Reaction

Structural Concrete, 2012
AbstractThis work investigates the effect of olive waste ash (OWA) on the durability of concrete exposed to alkali‐silica reaction (ASR). Three OWA contents were considered in the work: 7, 15 and 22 %, with crushed Pyrex glass used as reactive fine aggregate.

Characterization of Olive Waste Ashes as Fertilizers

2011
Wet and dry olive cakes are the most important wastes generated when olive oil is produced. In recent years, both olive wastes have been incinerated to produce electricity, and thereby large amounts of fly and bottom ash are generated. In this study, physical, physicochemical, and chemical characteristics of olive waste ashes produced in Andalusian ...

Utilization of Olive Waste Ash and Sea Sand Powder in Self-compacting Concrete

Iranian Journal of Science and Technology, Transactions of Civil Engineering, 2018
The main difference between self-compacting concrete (SCC) and other types of concretes is its aptitude for self-leveling. SCC can be achieved by using viscosity-modifying agents, superplasticizers, fillers or increasing the amount of fine aggregate.

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 ...
