Coal bottom ash (CBA) is a significant waste produced by the coal manufacturing power plant, harming the environment. CBA has been used in many studies to replace sand in cementitious materials. However, few studies have investigated the use of CBA in concrete as a sand replacement with densified silica fume (DSF) as a cement replacement. DSF is a...

Currently, there is no report on the combined use of ground coal bottom ash (GCBA) and ground granulated blast furnace slag (GGBS) as supplementary cementitious material (SCM) with lime kiln dust (LKD) as an additive in mortar. Hence, the current work aimed to investigate the impact of the addition of LKD on the properties of ternary blended cement...

Coal bottom ash (CBA), a by-product of the coal thermal power plant, can be classified as pozzolanic material according to ASTM C618. Therefore, it is a suitable supplementary cementitious material (SCM) in concrete. In recent developments, it was established that the pulverization of CBA enhanced the pozzolanic properties. Numerous prior studies o...

Coal thermal energy is the primary source of energy for many countries. Throughout the years, energy consumption has increased, causing coal energy consumption to spike. The use and production of cement in the construction industry also showed an increasing trend with global population growth and development. These two phenomena contribute signific...

The combination of ground granulated blast furnace slag (GGBS) and ground coal bottom ash (GCBA) as cement replacement material is not reported in the present works on ternary blended cement. Therefore, the present work was aimed to assess the physical and mechanical properties of cement containing GGBS and GCBA at various cement replacement ratios...
