Lab Report Example On the other hand, a dry density obtained through impacting of energy on the soil relies on the first initial content of water which is referred to as the moulding content of water. Getting to know the relationship between the moulding content of water and the achievable density is a topic that has been of concern for many years. The dry condition, and a moulding content water increase could lead into a high dry density compaction. The trend will continuous until when the maximum dry density is achieved at an optimum water content moulding. As the water increases, there would be a continuous dry density reduction. Such a reaction would be referred to as the curve of compaction. In order to gain a deeper insight concerning compaction, this experiment was set to investigate the compaction test. The sample mould base and mould mass would be determined to the nearest gram. The mould diameter and depth were measured. The mould depth was about 3 places where as the moulding diameter was about 6 places + or- 0.02 mm. The hammer, mass, proper drop, and square edges was checked for damages. A well-graded sand with fine that are less than five percent was used to ease the laboratory instruction. A material with particles that are oversize was selected to show the test aspects. Enough moist material was selected to give out approximately 12 kg of soil that is dry. The natural content of water was obtained. The amount of materials needed for the point of compaction was estimated. Five samples having contents of water separated by 1.5 percent were prepared. The water contents were adjusted such that they bracket the value that was optimum. The soil was tempered overnight to reduce the scatter in the data thus making it easy to define the curve of compaction. The compaction test was d one in respect to the standards of the ASTM test
