Conclusion In conclusion, the specific gravity of the aggregate is 2.705 form the virtual experiment. Form physical lab result we obtained bulk specific gravity(O.D), Bulk specific gravity (S.S.D), Bulk specific gravity (apparent) and water absorption are 1.878, 1.908, 1.937 and 1.605 respectively. The result from both are independent form each other as both aggregate tested are not the same.

CONCLUSION In this laboratory exercise "Sieve Analysis of Fine and Coarse Aggregates", I conclude that to know if an Aggregates are good to be used in a construction of structures and buildings is that we have to sieve an amount of gravel and sand from coarse down into fine pieces wherein different sizes will be separated and we will see if the sieved aggregates are well …

A conclusion is the last part of something, its end or result. When you write a paper, you always end by summing up your arguments and drawing a conclusion about what you've been writing about.
