Stabilized Soil

In order to reveal the effect of type of admixture and its content on the strength of stabilized soil, this paper uses the sludge as raw soil and cement, fly ash as curing agent, and analyzes the strength characteristics of samples mixed stabilized according to certain content. Using the unconfined compressive strength test, the compressive strength of the samples is tested. The effect of curing agent type and its content on the compressive strength is investigated. From the experimental results, it can be seen that the content of cement and fly ash has much effect on the strength. The conclusions obtained can have some conference values on the foundation treatment and reuse of waste resources utilization.

Sample Preparation Methods

Effects of two sample preparation methods on tensile strength of red clay are studied. The first method adopts standard layered-bumping to make sample whose layer interfaces are vertical to tensile force. The second method uses compaction apparatus to prepare big sample and the big sample is cut to prepare triaxial sample whose layer interface is parallel to tensile force. Test results indicate that the layer interfaces of soil sample have large influence on the single axle tension test, because the results of the sample prepared by 1st method have large dispersion and low strength, while the results of the sample prepared by 2nd method are just the opposite.Moreover,the layer interfaces of soil sample have little influence on the unconfined compressive strength test, and the results of the tensile test and unconfined compressive strength test of the samples prepared by 2nd method meet with the Griffith Criterion, so the samples of uniaxial tension test should be prepared by 2nd method.

Compressive Strength Test

In order to study the inorganic composite curing agents of lime, gypsum, fly ash on the strength properties of EPS lightweight soil using recycled sludge, the unconfined compressive strength test and scanning electron microscope test are done to investigate the strength properties of EPS lightweight soil. The effect and scope of each curing agent is investigated and determined by means of single-doped unconfined compressive strength test, and the optimum proportion of the curing agent is further determined by the method of orthogonal unconfined compressive strength test, of which the stabilized effectiveness of the lightweight soil is compared with those only using cement as curing agent. Finally, the SEM test is done to study the microstructure and pore characteristics of the lightweight soil mixed with EPS adding with or without curing agent. The test results and curing agent can be used as conference when stabilizing soft soil and treatment of discarded clay.

Engineering Significance

This paper has studied the different dosage of cement mixed with different proportions of gravel. Through the compaction and unconfined compressive strength test and economic analysis, and finally determined that the gravel mixed with content is 30% and the cement dosage is 3%. The study also shows that by adding a certain amount of gravel instead of powder is feasible. The same cement doses adding macadam mixture, unconfined compressive strength is higher than stable powder. The study has solved the shortage of raw materials of construction, saving a lot of money, and has important engineering significance.

Improving MSW with help of the curing agent mixed with cement, fly ash and gypsum. The unconfined compressive strength test is carried out in different conservation age on the improved MSW; Analyzing the increasing mechanism of improved MSW combined with the method of SEM/EDS. Simulating acid alkaline environment with the liquor of H2SO4 and NaOH and studying the rule of acid and alkali erosion of improved materials. The result of experiment show that improved MSW which contain cement, fly ash and gypsum is better than it only mixed with cement; The strength of improved MSW mixed with cement is better than it only have cement ,and improve more in lye.

Based on the engineering properties of the peat soil in Kunming, through indoor unconfined compressive strength test in this article, and changing the different cement mixing ratio including 12%, 15%, 18%, 21%, 24% and 27% and age including 3 d, 7 d, 14 d, 28 d, 60 d and 90 d, and we focus on the influence on unconfined compressive strength of cement-soil by both of them. Through the study of the regression analysis of test results, we obtain the basic strength characteristics of cement-soil of peat soil which is that cement-soil unconfined compressive strength increases with group of the cement mixing ratio and age and showing a good correlation between them. And the unconfined compressive strength of cement-soil with the increase of ratio presents approximate linear growth and a logarithmic curve approximation along with the age growth, and the growth rate is smaller and smaller.

Stabilized Soil

In order to reveal the effect of admixture type and quantity on the strength of stabilized soil, a series of indoor test is done on the stabilized soil by means of unconfined compressive strength test. The raw material soil used in the experiment is sludge soil, and cement, triethanolamine, caustic soda are used as admixture. A lot of solidified samples are prepared according to test scheme in different admixture’s proportion. From the test results, it can be seen that different admixture and it’s quantity affect the strength of stabilized soil by analyzing the sample’s unconfined compressive strength test results.
