Each year, about 730 million tons of bottom ash is generated in coal fired power plants
worldwide. This by-product can be used as partial replacement for Portland cement, favoring …

The world is facing considerable challenges with managing wastes and by-products, mainly
hazardous materials. On the other hand, the construction sector still needs to source …

Over the past decades, a wide number of research programs were conducted and
demonstrated the efficiency of supplementary cementing materials (SCMs) to mitigate alkali …

Sugarcane bagasse ash (SBA) is a supplementary material widely used around the world
for improving mechanical and durability properties of concrete. Main aim of this study was to …

The degradation of large concrete structures over time is well known. One of the main
reasons is the reaction that occurs between the cement paste and some reactive siliceous …

Municipal solid waste incinerator bottom ash was evaluated for its alkali aggregate reactivity
in cement mortars. Subsequently, two wastes were evaluated as supplementary …

The focus of this study is to both quantitatively and qualitatively assess the effectiveness of
pulverized ultra-fine bottom ash as a cement replacement to mitigate the detrimental effects …

Coal has been increasingly used in the past few decades as a fuel source in power plants
and industrial facilities in many countries. The escalating demand for coal has been …

The potential for binary and ternary blends of metakaolin, with two differing particle size
distributions, and Class C fly ash to mitigate alkali-silica reactions (ASR) with a highly …

A comprehensive investigation was conducted to determine the individual effects of the
chemical composition and particle size of fly ash on alkali-silica reaction (ASR). Test results …
