Properties of self-compacting concrete containing olive waste ash

Cement Wapno Beton, 2020
Reasonable and standardized use of local and waste resources is of great importance for the economic development in the world. The utilization of waste materials can result in enhanced properties and eco-friendly concrete, at the same time. In this study, it is aimed to evaluate the effect of olive waste ash on the mechanical and fracture properties of

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

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 elevated temperatures

Fire Safety Journal, 2009
Abstract This study explores the influence of olive waste ash (OWA) on the performance of concrete exposed to elevated temperatures in the range from 400 to 600 °C. The performance of concrete to elevated temperature was evaluated using compressive strength and electrical charge of concrete.

Potential Use of Olive-Waste Ash from Cogeneration Plants as a Soil Amendment

Journal of Environmental Science and Health, Part B, 2006
A greenhouse study was conducted to evaluate the potential use of olive-cake ash as a soil amendment, using pepper (Capsicum annuum, L. cv Italian sweet). Three soils of different pH (acidic, neutral and calcareous) were used. Treatments included a control (no fertilizer application), NPK fertilizer, and two ash-application rates that provided a ...

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.

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.

Effect of olive waste ash on the properties of high‐strength geopolymer concrete

Structural Concrete
AbstractThis 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 OWA as a partial ...
