چکیده

The stability of loess subgrade is affected by many factors. Freeze-thaw cycles are a common factor that causes the strength subgrades to be damaged. In order study influence freezethaw on subgrades, reveal mechanism freeze-thaw subgrades. It necessary sample soil samples in this area, and perform compaction test, cycle unconfined compression test electron microscope scanning analyze microstructure soil. . way, potential relationship between can obtained. results found led trend first increase then decrease strength. showed smaller particles increased voids. was analyzed. explains conclusion increases decreases.

Test Study on Strength and Permeability Properties of Lime-Fly Ash Loess under Freeze-Thaw Cycles

In order to study the application of lime-fly ash loess in permafrost subgrade engineering, uniaxial compressive test, fast direct shearing test and permeability tests were carried out on lime-fly ash loess under different curing ages and freeze-thaw cycles. Uniaxial compressive strength of lime-fly ash loess increases slowly with the curing ages, and can reach 3.5 Mpa after the curing ages of ...

Using PCR and culture methods for Mycoplasma testing

Mycoplasma contaminants can be considered important not only for their roles as pathogens but also they may indicate that insufficient care has been taken during vaccine manufacture or quality control. The purpose of this study was to test the poliomyelitis vaccines for Mycoplasma by culture and polymerase chain reaction (PCR) methods. During 2008 to 2009, a total of 47 lots of oral poliomyelit...

Effect of Fast Freeze-Thaw Cycles on Mechanical Properties of Ordinary-Air-Entrained Concrete

Freezing-thawing resistance is a very significant characteristic for concrete in severe environment (such as cold region with the lowest temperature below 0°C). In this study, ordinary-air-entrained (O-A-E) concrete was produced in a laboratory environment; the compressive strength, cubic compressive strength of C50, C40, C30, C25, and C20 ordinary-air-entrained concrete, tensile strength, and ...
