In order to study the effects of soda residue content, particle size, moisture content, and curing age on the unconfined compressive strength (UCS) of soda residue cement lime soil (SRCLS), a 4-factor, 4-level orthogonal experimental design was employed in this study. Different conditions of SRCLS UCS and their impacts were tested and analyzed. The internal …
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.
To broaden the sources of earthwork and the utilization of soda residue (SR) and fly ash (FA), SR, FA, and clay were mixed to form a soda-residue soil (SRS) by adding externally moderate content of lime or/and cement for further stabilization. Through the orthogonal scheme, 9 groups of proportions were designed. Subsequently, the unconfined compressive …
The purpose of this study was to propose a method to quantify the volumetric crack rate (VCR) of red clay and investigate the influence of VCR on the unconfined compressive strength (UCS) of red clay. First, the relationship between wave speed and VCR was quantified by a prefabricated crack method to obtain the equivalent VCR (EVCR).
methods of evaluating the strength of a cement-treated sandy soil. These two methods are the California Bearing Ratio test and the unconfined compressive strength test. However the equation, log CBR = 1.115 + 0.660 log UCS, can be used as a …
The primary difference between confined and unconfined compression tests is that the sample in an unconfined compressive strength test is not restrained laterally. The unconfined compression test is …
Combined with the unconfined compressive strength (UCS) and leaching of heavy metal pollutants from Pb-Zn tailings, the feasibility of applying microbial induced carbonate precipitation (MICP)-treated Pb-Zn tailings to embankment materials was analysed from the perspective of strength and environmental performance. The results showed that the ...
between strain hardening and softening is called the unconfined compressive strength of the rock and is denoted as Co or qu. Failure takes place continuously from C to D during which macrocracking takes place as the rock becomes more deteriorated and …

percentage of CFA, the crusher run was mixed with various percentages of Class F CFA, including 10%, 15%, 20%, and 25%. The proctor Compaction test (PCT), soaked and unsoaked California Bearing Ratio (CBR) tests, and Unconfined Compressive Strength Test (UCST) were then used to evaluate the bearing capacity of the CFA-treated crusher. The result

An experimental study on the unconfined compressive strength properties of cement stabilized/solidified heavy metal contaminated soils is presented. The heavy metal contaminated soils are prepared in the laboratory by adding lead nitrate as a source of pollutant. Cement is used as a S/S binder with different contents.
The unconfined compressive strength (UCS) of intact rocks is crucial for engineering applications, but traditional laboratory testing is often impractical, especially for historic buildings lacking sufficient core samples. Non-destructive tests like the Schmidt hammer rebound number and compressional wave velocity offer solutions, but ...
f-d, I have to do a soil stabilization with lime or cement for a pavement subgrade. Clients are more familiar with improved qu (unconfined compressive strength) values however, most of the contractors shown improved CBR values in their catalogs. I just wanted to look at different correlations betweeen qu and CBR to compare with what we have here.
Unconfined compression (UC) is a valid strength test for most cohesive soil types, but there are some exceptions: Soils that expel or bleed water during testing and do not retain strength after loading.
