Studi Pengaruh Aditif Semen Terhadap Konsolidasi Tanah Lempung
Abstract: Soil stabilization
with additive materials cement is one of the alternatives to soil improvement.
Usage of cement for the materials of soil stabilization, beside because easy go
to cement and many there are specially in Padang, execution of soil
stabilization by using cement additive materials is easy to do. Testing which
cove the physical nature that covering specific gravity for original soil that
have been mixed by materials of cement additive liquid limit, plastic limit
which is each was also conducted to original soil and soil mixed by cement
additive, and also the mechanical properties suchas consolidation that all the
test followed ASTM standards. Cement additive materials rate used is 0
(original soil), 5 %, 10 %, and 15 % with respect to dry weight of soil, where
before made by object test in each mixture done by examination of condensation
and each object test was cured former each during 0, 3, 7 and 14 days. The
index value to original soil plasticity is 29,62%. After stabilization with
cement additive materials make degradation to the plasticity index of the
original soil, where degradation that happened as according to improvement of
rate of cement additive. From the test of consolidation conducted the behavior
that is progressively go up usage of rate of cement additive, hence will cause
progressively go down that to compression index value (Cc).
Keywords: clay, soil stabilization, materials
