The hydraulic materials, such as Ca (OH)2, ettringite and calcium silicate hydrate and so on, which are generated from the hydration reaction, cause the treated products to have good mechanical properties[8].
PFA is similar pozzolanic materials, with inorganic ion-exchange properties and adsorption decolorization, it can absorb pollutants in sludge.
Results and Discussion Orthogonal Experiment The mass fraction of the cement, the PFA and the cinder, as well as the conservation days were the factors in the orthogonal experiment.
Condusions a) After solidifying by using cement, fly ash, cinder and curing for formation, the textile dyeing sludge had good physical and mechanical properties.
b) The compressive strength of cured block increased as the content of cement and cinder increased, which shows that the addition of cement and cinder was beneficial to improvement of the mechanical properties of sludge solidified block.

However, the amount of risk is dependent on the nature and volume of the oil besides other abiotic factors such as the sensitivity limit of the marine habitat.
These factors create limitations, which possessa challenge in recent years.
Factors limiting oil spill mitigation Oil spill clean-up is a rigorous exercise due to several factors that influence its control.
Some of these factors are discussed briefly as follows: Salinity.
Intrinsic absorbing properties.

The Effect of Annealing Conditions and Alloying Elements on the Microstructure Stability and Mechanical Properties of Mg-Zn-Cesheets M.
Mechanical properties of these rolled and annealed sheets were determined in rolling and transverse directions.
The UTS is the same between these twoalloys, so the cerium doesn’t affect the UTS values.
Besides, the effect of alloying elements on mechanical properties was investigated.
