Linear Identification of Rotary White Cement Kiln
Rotary cement kiln is the main part of a cement plant that clinker is produced in it. Continual and prolonged operation of rotary cement kiln is vital in cement factories. However, continual operation of the kiln is not possible and periodic repairs of the refractory lining would become necessary, due to non-linear phenomena existing in the kiln, such as sudden falls of coatings in the burning ...
متن کاملThe Effect of Curing Temperature on White Cement Hydration
Cement manufacture has undergone extensive change in its attempts to rise to the successive challenges posed by society. The hydration of Portland cement is a complex phenomenon that depends on both reagent characteristics and reaction conditions. It is a well-known fact that the curing temperature plays an important role on the hydration kinetics. The present study is the first to be undertake...
متن کاملSingle-Point Imaging of Partially Dried, Hydrated White Portland Cement
Moisture content in concrete has a major influence on the concrete samples with spin-echo imaging methods (15, 16) . The spin–spin relaxation times of water in these rehydration durability and mechanical properties of the material during its service life (1, 2) . Resistance to corrosion, ability to experiments is only a few milliseconds so the quality of traditional spin-echo images is disappoi...
متن کاملRemoval of White Mineral Trioxide Aggregate Cement: A Promising Approach
Removal of MTA from dentin by applying 37% hydrochloric acid (HCl) to reduce microhardness and push-out bond strength. Forty dentin slices were filled with WMTA and divided into two groups (n = 20). Ten slices remained untreated while others were exposed to either HCl or phosphate buffer saline (PBS) and all samples were subjected to pushout test. The mode of bond failures was determined by SEM...
متن کاملMicro- and nano-structural evolutions in white Portland cement/pulverized fuel ash cement pastes due to deionized-water leaching
Thin slices of white Portland cement-low calcium pulverized fuel ash (pfa) blended cement pastes containing 30 or 50% pfa were leached progressively in de-ionized water. The paste with 50% pfa was aged 13 years prior to leaching and those with 30% pfa were aged 1 and 13 years. Pastes were leached for up to 75 days and were characterized using thermal analysis, X-ray diffraction, analytical scan...
