However, by the year of 2008, the sludge deposition ran up to 534,840,000 cubic meters, which took 20 percent of the reservoir capacity; therefore, sludge deposition of substantial reservoirs in Taiwan is now extremely urgent and calls for immediate processing. CFB byproduct lime is the byproduct in the process of power generation of circulating fluidized bed boiler. For the purpose of improving the economic value of the recycling of CFB byproduct lime and reservoir sludge, this research takes Shimen Reservoir sludge and CFB byproduct lime of Formosa Petrochemical Corporation as the objects of research and adds cement as cementing material; test parameters contain water content (70% and 90%), water cement ratio (4, 5 and 6), water byproduct lime ratio (1, 2, 3 and 4) and various ages. And a research on solidification effect of CFB byproduct lime of Formosa Petrochemical Corporation will be carried out though compressive strength test, water absorption test, strength durability test and drying shrinkage test. The research indicates that mixing proportions can all reach the required fundamental strength of 3kg/cm2 for clearing and delivering reservoir sludge except the 3-day strength of S90C5L4 and S90C6L4 (water content is 90%, water cement ratios are 5 and 6 and water byproduct lime ratio is 4) being lower than 3kg/cm2. When the water content is 90% and the water cement ration remains the same, compression strength of test specimens would be reduced with the increase of the water byproduct lime ratio; however, the drying shrinkage would be greatened with the increase of the water byproduct lime ratio. The water cement ratio being equal, water absorbing capacity would be raised with the increase of water byproduct lime ratio whether the water content is 70% or 90%.
