ON A NEW DRYER FOR SLAG OR FLY-ASH姜洪舟,李应开摘 要:<正>Granulated blastfurnace slag or fly-ash, asadmixture of slag cement or pozzolana cement, has to be driedbefore it is ground with clinker, for it contains water. Here, anew dryer for drying slag or fly-ash is recommended,which iscalled suspension dryer.关键词:......
fluidity, high elastic modulus, low adiabatic temperature rise and low drying shrinkage, which cannot be satisfied by ordinary SCC. In this study, in order to solve the problem, a few principles of SCC design were proposed and the effects of binder amount, fly ash(FA) substitution, aggregate content and gradation on the workability, temperature rise, drying shrinkage and elastic modulus of SCC were......
ability of nickel–titanium slurry and the mechanical properties of nickel–titanium sintered body were studied. The drying models under different solids loading were also discussed.The results show that the viscosity of slurries significantly increases with an increase in solids loading. After a proper process of drying, the green body with complex shape is obtained. The sintered body with porosity......

="ChDivSummary" name="ChDivSummary">The properties of the carbonated brick made of steel slag-slaked lime mixture such as strength, drying shrinkage, water absorption and soundness were mainly investigated. The experimental results indicate that, after carbonation, the strength of the brick increases, its drying shrinkage reduces, and its soundness becomes eligible. The optimal slaked lime/steel......
