PROPERTIES OF ALKALI-ACTIVATED FLY ASH CONCRETE BLENDED WITH SLAG

Using Scrap Tires in EAFs as a Substitute for Carbon

EAF plants normally consume coal and coke as reactants, alloying elements, or fuel. The price of these materials varies from € 0.20-0.35/kg. This is while nearly 10 million pieces of tires are annually discarded in Iran. The present study shows that scrap tires can be used as a substitute for coal and coke in EAF plants. Thirteen grades of steel including low, medium, and high carbon steels as ...

Utilisation of two-stage waste incinerator bottom ash as a cement substitute in concrete

Waste incineration still seems to be an essential technology in the concept of integrated waste management. However, the desirable quantity of waste incineration residue needs to be as low as possible. Therefore, related optimization of two-stage waste incineration technology has been performed with the main goal of producing lower amounts of boiler ash, fly ash and flue gas-treatment residue, ...

Durability Study Partially Saturated Fly Ash Blended Cement Concrete

This paper presents the experimental results of the investigation of various properties related to the durability and longterm performance of mortars made of Fly Ash blended cement, FA and Ordinary Portland cement, OPC. The properties that were investigated in an experimental program include; equilibration of specimen in different relative humidity, determination of total porosity, compressive ...

Analysis and Modeling of Yield, CO2 Emissions, and Energy for Basil Production in Iran using Artificial Neural Networks

The present study attempts to investigate the potential relationship between input energies, performance production of greenhouse basil, and greenhouse gases emitted from this product. The data were collected from 24 greenhouses using a questionnaire and verbal interaction with farmers. Results of the study showed that the total input energy and total output energy for basil production were 119...
