Compressibility behaviour of magnesium phosphogypsum amended laterite

Laterite mining is not a new economic activity for Malaysia. The mining of laterite has taken place in the state of Johor since early 2000. Laterite is considered as problematic soil because it is a waste product. There are a number of reasons why laterite mining can cause problem which will subsequ...

The mining of laterite has taken place in the state of Johor since early 2000. Laterite is considered as problematic soil because it is a waste product. There are a number of reasons why laterite mining can cause problem which will subsequently propagate to problems if the issue is not resolved or controlled. This research focused on the compressibility behaviour of Magnesium Phospogypsum with respect to oedometer test. The result is useful to be implemented in industry to provide efficient waste disposal or reuse the waste materials in the context of industrial waste issues. Result from the oedometer test reveal that the magnitude and rate of volume decrease that a laterally confined soil specimen undergoes when subjected to different vertical pressures. This is caused by deformation of soil particles, relocations of soil particles and expulsion of water or air from the void spaces. Three different sample is used in this research. The water content before test for sample 1, sample 2 and sample 3 are 38.3%, 49.1% and 47.5% respectively. After the experiment, water content for each loading decreases as the pressure increases. For sample 1, water content decrease from 34.54 to 22.74, sample 2 decrease from 44.4% to 31,00% and sample 3 decrease from 38.1 to 25.3 respectively. The initial void ratio before test for sample 1, sample 2 and sample 3 are 1.0131%, 1.3039% and 1.2472% respectively. After the experiment, void ratio for each loading decreases as the pressure increases. The void ratio after compressibility for sample 1 decrease from 0.9725 to 0.3364, sample 2 from 1.2623 to 0.8088 and sample 3 from 1.2342 to 0.7586 respectively This finding implies that the compressibility behaviour of Magnesium Phosphogypsum relate to the pressure impose to the soil sample. 2018-06 Undergraduates Project Papers NonPeerReviewed pdf en http://umpir.ump.edu.my/id/eprint/27592/1/Compressibility%20behaviour%20of%20magnesium%20phosphogypsum%20amended.pdf Nurul Nabila, Adenan (2018) Compressibility behaviour of magnesium phosphogypsum amended laterite.
