Keywords: - Industrial waste sand, Lime, Atterberg limits, Unconfined Compressive Strength and California Bearing Ratio Test 1. INTRODUCTION The sub-base is an important layer in both flexible and rigid pavements.


The unconfined compression test allows you to quickly measure the compressive strength for cohesive soils and is a core offering for most laboratories. Once a soil sample is in place, and the test conditions selected, the system will run the entire test from start to finish. Applicable Test Standards. ASTM D1663, D2166; AASHTO T 208

SOIL-LIME TESTING

5.4.1 Lime-treated subgrade soil specimens should be compacted as nearly identical as possible and three specimens cured and tested for unconfined compression. 5.4.2 If the material to be improved by lime treatment is a flexible base material, the unconfined compression test is used to evaluate the strength. Compact three identical


Unconfined Compression Stress (UCS) Test The lime used in this study was calcium hydroxide (traditionally called slaked lime), Ca(OH) 2. The lime content was optimized at a content of 12% based on the preliminary test results by the authors, and the corresponding mixture was used for subsequent lime-cement laterite soil stabilization


Unconfined samples are uni-directionally loaded gradually till failure in this test. This is an Electrically operated (Motorized) instrument for determining the unconfined compression strength of soil specimens of diameter ranging from 38 mm to 100 mm.


The unconfined compression test is by far the most common, cheap and fastest method for soil shear testing. The unconfined test is used for cohesive, saturated soils. This test is inappropriate for dry sand or crumbly clays. This is essentially a special case of the triaxial compression test where the minor principal stress is zero.


Compression testing of soil-lime specimens is performed to determine unconfined compressive strength of the cured soil-lime-water mixture to determine the suitability of the mixture for uses such as in pavement bases and subbases, stabilized …


The unconfined compression test is the most popular method of soil shear testing because it is one of the fastest and least expensive methods of measuring shear strength. It is used primarily for saturated, cohesive soils recovered from thin-walled sampling tubes. The test is not applicable to cohesionless or coarse-grained soils.


Jul 11, 2012· The unconfined compressive strength test was used as a simple means to measure the unconfined compressive strength of a non-treated specimen and three lime-treated specimens of Austin's soil.
