Cement Kiln Dust (CKD), was collected from Suez Cement Company, located at K30 Maadi/Ain Sokhna Road, Cairo, Egypt. It was dried for 24 h at 105 °C. The wastewater used in this study was a composite sample of raw water that was collected from different sites along the Nile River-Damietta Branch, (Fig. 1).
This study investigates the effect of the partial replacement of ordinary Portland cement (OPC) with cement kiln dust (CKD) on the engineering properties of pozzolanic concrete for use in block manufacturing. Ultimately, this could potentially reduce cement consumption and CO2 emissions. The study was carried out on cylindrical …
exposures to wet cement kiln dust, cement kiln dust mixtures or liquids from wet cement kiln dust. Burns should be treated as caustic burns. Cement causes skin burns with little warning. Discomfort or pain cannot be relied upon to alert a person to a serious injury. You may not feel pain or the severity of the burn until hours after the exposure.
