Lime Stabilization of a Virginia Clay Soil
The fact that when lime is added to clayey soils same very beneficial results are produced dates back into the remote past. It is not a new development, In the United States lime has been in use since l923. The objective of this study was to determine the effect of increasing soaking time of …

Assessment of the fate of Cryptosporidium parvum, Giardia lamblia and Ascaris lumbricoides in class A composting and class B lime stabilization biosolids treatment processes
… the persistence of parasites in Class B lime stabilization and Class A composting. Results of the lime stabilization procedure show evidence that this method is effective in reducing bacteria concentration, but that the parasites persisted throughout the treatment process. The Class A …

Evaluation of bacteriophage and viral persistence during alkaline stabilization in sludge and biosolids intended for land application
<p>The use of lime to reduce or eliminate pathogen content is a cost-effective treatment method currently being employed in many Class B biosolids production plants in the United States. A bench scale model of lime stabilization was designed to evaluate pathogen persistence. The survivability of …

Investigation of stabilized Berea Red soil with emphasis on tensile and cyclic triaxial tests
… improve it. Special attention has been paid to lime stabilization and different curing techniques. Gradings, special indicators and California Bearing Ratios were determined on both natural and lime stabilized Berea Red soil. Consolidometer tests were performed on natural and lime or cement …

Factors Contributing to Trimethylamine Generation from Limed and Polymer Conditioned Sludges
… (CH3)3N, (TMA), odors are often associated with limed and polymer conditioned sludges. This odor has a fishy smell and can be a nuisance to the community surrounding a wastewater treatment plant or land application site. Several factors are thought to determine the amount of TMA generated from …

Estabilização de areia com cinza volante e cal; efeito do cimento como aditivo e de brita na mistura
Study on the stabilization of sand with fly ash and hidrated calcitic lime, and the effects of admixing portland cement and crushed stone on the compressive strength of the mix. In order to enhance fly ash role the soil chosen was a non-cohesive one - a uniform dune sand - which is not quite …

Lime, cement, and lime-cement stabilization of a clay soil
… had been stabilized with various percentages of lime, cement, and combinations of the two. In both cases where the additives were added separately to the soil, the percentages used were 5 and 10 per cent by dry weight of soil. In the additive combination study, lime-cement percentage additions …

Investigating the Role of Various Environment and Process Conditions in Wastewater Sludge Odor Generation
… compounds and nitrogen containing compounds. Lime stabilization is a technique which is commonly used in the wastewater industry to produce biosolids having reduced odors that can be safely land disposed. In this research, odors produced from dewatered sludges and lime stabilized biosolids …

Evaluation of Moisture, Suction Effects and Durability Performance of Lime Stabilized Clayey Subgrade Soils
… and unconfined compressive strength (UCS) of lime treated clayey subgrade soils. Two subgrade soils: the AASHTO class A-6 and A-7-6 are collected from US 491 road site in New Mexico. Cylindrical soil specimens are prepared according to NCHRP 1-28A at three lime percentages: 0%, 5% and 7% which …

Soil stabilization utilising wastepaper sludge ash
… non-renewable natural resources.<br/><br/>In lime-stabilization of sulfate-bearing clay soils, there has been increasing concern over the damage caused by the expansion which is produced when sulfate-bearing soils are encountered. The main objective of this research was to investigate the …

Soft computing based parameter identification in pavements and geomechanical systems
… flexible pavements, were built on either lime stabilized soils or untreated subgrade. Nonlinear properties of the subgrade soil and the base course aggregate as transportation geomaterials were also considered. A computer program, Soft Computing Based System Identifier or SOFTSYS, was …
