Eco-Geopolymers: Physico-Mechanical Features, Radiation Absorption Properties, and Mathematical Model.

Waste ashes and radiation are hazardous environmental and health factors; thus, a lot of attention is paid to their reduction. We present eco-geopolymer building materials (GPBMs) based on the class F fly ashes (FFAs) from thermal power plants (TPPs) and their implementation as a barrier against radioactive radiation. Different methods of production, ratios of FFA to alkali activator, and temperatures of curing were tested.

Process Development of Fly Ash-Based Geopolymer Mortars in View of the Mechanical Characteristics.

This study aimed to determine the effects of design parameters, including the liquid/solid ratio (L/S), NaSiO/NaOH weight ratio, and curing temperature, on class F fly ash-based geopolymer composites. For this purpose, two disparate sources of fly ash were supplied from Çatalağzı (FA) and İsken Sugözü (FB) Thermal Power Plants in Turkey. Two different L/S ratios of 0.

Eco-Friendly Fired Brick Produced from Industrial Ash and Natural Clay: A Study of Waste Reuse.

Bottom ash (BA) is an industrial solid waste formed by the burning of coal. The environmental problems and storage costs caused by this waste increase with every passing day. In this study, the use of BA as an additive (clay substitute) in fired brick production was investigated.
