Cement dust exposure and acute lung function: A cross shift
2010年4月14日 Cement dust exposure. The highest geometric mean dust exposure was found in the crusher section (38.6 mg/m 3) followed by the packing section (18.5 mg/m 3) and the guards (0.4 mg/m 3).The range of exposure was high in both the crusher and packing sections (Table 1).Within each of these sections exposure was highest during

Cement Kiln Dust (CKD): Characterisation and utilisation in cement
Cement kiln dust (CKD) is a by-product of the cement manufacturing process. Despite the fact that usually its composition is similar to partially calcined raw feed, the variability in raw materials, fuel, type of process, dust collection systems and product specifications influence both the physical and chemical characteristics resulting in a highly variable material.

Dust from chlorine bypass installation as cementitious
2022年7月1日 Abdel-Ghani et al. [21] proposed the production of fabricated cement bricks and interlock paving blocks having a cement content of 210–250 kg/m 3 and 450 kg/m 3, respectively, with 20% cement bypass dust addition. Taha et al. [53] found that substituting 5% of lime or cement with bypass dust is the optimum applied in asphalt paving mixtures.
