...Sandeep Singh; Shashi Kant Sharma; M. Abdul Akbar Purpose The purpose of this work is to improve the air entrainment capacity of a concrete by using fine mineral admixtures such as fly ash (FA) and silica fume (SF) as cement substitute, and coal bottom ash (CBA) as fine aggregate substitute. Air...

... their environmental impact. One potential usage is in road subbase fill materials where wastes can be incorporated in large quantities. In this study, the engineering properties of road subbase fill materials (i.e. kaolinite) mixed with Granite Waste (GW), coal Fly Ash (FA) and lime are investigated. Kaolinite...

... its lifetime (Portland Cement Association, 2019). This study aims to focus on introducing CO₂ to normal and fly ash concrete and thus investigating the effect on the carbon footprint of the samples and the effectiveness of the CO₂ introduction methods, namely, carbonated water...

... benefits. Industrial wastes, such as fly ash (FA) and ground granular blast furnace slag (GGBS), have been extensively used to manufacture unitary and binary geopolymer concrete with heat activation (at different temperature); however, it has indicated a limitation for its application in precast industry...

...Eric Asa; Monisha Shrestha; Edmund Baffoe-Twum; Bright Awuku Purpose Environmental issues caused by the production of Portland cement have led to it being replaced by waste materials such as fly ash, which is more economical and safer for the environment. Also, fly ash is a material...
