Conclusion Comp Action Tes

CONCLUSION The test consists of compacting the aggregate to be tested into a standard mold using a standardized compactive energy at several different levels of moisture content. The value of maximum dry density and optimum moisture content is determined from the results of the test is 2.282 g/cm3 and 0.053. The maximum dry density is obtained at this optimum moisture content. The objective of this experiment is achieved. We can conclude that the the optimum moisture content increased while maximum dry density decreased with increasing bagasse. This compaction behaviour occurs as a result of both the grain size distribution and specific gravities of the soil and the modified cement and bagasse in this case. The modifier initially coats the soils to form larger aggregates, which consequently occupy larger spaces. The increase in optimum moisture content may be due to water requirement for cement hydration and pozzolanic reaction of the lime released during hydration of cements. Compaction is the process of increasing the bulk density of a soil or aggregate by driving out air. For any soil, for a given amount of compactive effort, the density obtained depends on the moisture content. At very high moisture contents, the maximum dry density is achieved when the soil is compacted to nearly saturation, where (almost) all the air is driven out. At low moisture contents, the soil particles interfere with each other; addition of some moisture will allow greater bulk densities, with a peak density where this effect begins to be counteracted by the saturation of the soil.
