INTRODUCTION TO GEOTECHNIC
:star:
IGNEOUS ROCK
:smiley:
characteristic
:<3: contain no fossil
:<3: no layering
:<3: react with acid
:<3: light or dark colour
:smiley:
type of rock
:<3:scoria
:<3:gabbro
:<3:granite
:<3:basalt
:<3: formed from molten liquid mineral known as magma that lie below earth crust
:star:
METAMORPHIC ROCK
:smiley: type of rock
:<3:gneiss
:<3:slate
:<3:marble
:<3: formed by applying great pressure and temperature
to existing rock converting into new distinct rock
:smiley:characteristic
:<3:react with acid
:<3: has fossil
:<3: has pore and opening
:star:
SEDIMENTARY ROCK
:smiley: characteristic
:<3: contain fossil
:<3:react with acid
:<3: colour variety
:smiley:: type of rock
:<3:limestone
:<3: sandstone
:<3: shale
:<3: Formed by the lithification (cementing,
compacting and hardening)
:smiley:organic soil
:<3:not suitable in support foundation
:<3: example : peat soil
:<3: 150 - 300 mm from soil surface
:smiley: residual soil
:pencil2:remain at the place of formation
:<3: upper zone
:<3:partially weathered zone
:<3:intermidiate zone
:smiley:transported soil
:pencil2: stay in the same place or may be moved to other place by ice water , wind and gravity
:<3: marine soil
::<3:glacial soil
:<3:alluvial soil
:smiley: mechanical weathering
:<3: frost
:<3: thermal expansion
:<3:plant roots
:<3:abrasion
:smiley: biological decomposition
:<3: microoganism
: :<3:bacteria
:smiley:chemical decomposition
:<3:leaching
:<3:hydration
:<3: oxidation
:smiley:Distributed soil sample
:<3:do not retain in-situ properties of soil during collection process
:smiley:undisturbed soil sample
:<3: retain the structural integrity of in-situ sial and have high recovery rate with sample.
