Improvement in concrete behavior with fly ash, silica-fume and coconut fibres

Construction and Building Materials, 2019
Concrete is one of the most widely used construction material in spite of some inherited issues (brittleness, weak in tension, etc.). A lot of effort has been made to alter concrete behavior with the help of additives e.g.

Effects of chemical composition of fly ash on compressive strength of fly ash cement mortar

Construction and Building Materials, 2019
The effect of the chemical composition of the amorphous and crystalline phases of fly ash on the compressive strength of fly ash cement mortar was studied. The fly ash cement mortars were made by replacing 25 wt% of cement with 16 types of fly ashes, and

Ash dieback

2022
Ash dieback in Europe is caused by an invasive alien pathogen originating from East Asia, the helotialean ascomycete fungus Hymenoscyphus fraxineus. This disease first emerged in the early 1990s in NorthEastern Poland, and the pathogen successively invaded most of Europe, in total 32 countries, in the next decades, causing substantial damage and ...

Characterization of cement stabilized pond ash using FTIR spectroscopy

, 2020
Pond ash is a mixture of fly ash and bottom ash obtained from thermal power plants. It has pozzolanic properties and is commonly treated with cement to impart cohesion and improve strength. The increase in strength gain in cemented pond ash is attributed

Effects of nano-SiO2 on early strength and microstructure of steam-cured high volume fly ash cement system

Construction and Building Materials, 2019
The utilization of fly ash in concrete production can reduce pollution as well as decrease greenhouse gas emission. However, a high replacement ratio of cement with fly ash largely reduces early strength, and this is the main obstacle for industrial ...
