Reducing cement consumption for cement-based goods such as mortar, concrete, and paving blocks may drastically cut CO2 emissions, which result in 0.9 tonnes of CO2 per 1 tonne of cement [15]. Cement manufacturing has accounted for approximately 8% of worldwide CO2 emissions [16]. The main ...
The precursor material is waste from the coal based power plant called fly ash that produce 219.000 tonne per year and still underutilized but potentially as an alternative to cement. In this study, seawater was used to substitute the sodium hydroxide in alkali activator as an effort to reduce...
