PERBANDINGAN KUAT TEKAN SILINDER TAK TERKEKANG DENGAN CONE INDEKS PADA TANAH DICAMPUR DENGAN SEMEN
Abstract: Since 1981, Indian
geotechnical expert have been introduced shear strength of soil is cone index
(CI). Recently, common existing shear strength index in soil mechanic studies
such as N-SPT, qc-CPT.However, the cone index (CI) parameter till in this time
not yet been made by standard of the testing of soil sample in the soil mechanics
laboratory. Pursuant to this problem, we have correlated cone index (CI) with
unconfined compression strength (qu). The research used two measurement are unconfined compression and
penetration ofcone bar silinder into soil sample. Diameter cone bar penetration
is 0.5 cm, high 7 cm and cone angle part of 60 degree. The soil samples for
research from Indrapuri sub district, Aceh Besar. For strength variation soil
sample mixed cement with content 0%, 3%, 6% and 9% with waiting periode of
samples 0, 2 and 4 days. The results of research showed good and strong
correlation between cone index (CI) and unconfined compression strength (qu).
Parameters with R2 80% from linear comparison.
