Effects of Compaction and Curing Conditions on Geo-Engineering Behavior of Lime Stabilized

Expansive Soil

Abstract:

he modification of engineering properties such as plasticit!" s#elling" shrin$age" and strength

of an expansive soil has become ver! relevant to geotechnical engineers" as expansive soil coversalmost %&' of land area in (ndia) he most commonl! used additives for soil stabilization are

*ortland cement" lime and fl! ash) o provide necessar! al$ali environment for activation of the

expansive soil GGBS ma! use in combination #ith calcium h!droxide" +*C" sodium h!droxide"

sodium carbonate" and sodium silicate) he value of plasticit! index" volumetric shrin$age" linear

shrin$age" and free s#ell index of the stabilized soil decreased #ith the increase in the

percentage of lime) ,aximum dr! densit! decreased #hile optimum moisture content increased

#ith the increase in lime content) (t has found that strength development increases #ith the

increase in curing age and lime content) ,icro-structural anal!zer used to establish a correlation

bet#een the observed engineering properties #ith the h!dration products" microstructure" and

morpholog! of the specimens)

Abstract

he properties of the dredged material #hich consist of sand" silt and cla! depend on numerous

factors such as particle size distribution" particle shape" pore #ater" and temperature) ere matter

of concern is ho# the effective utilization of the dredged material possible because it undergoes

the problem of siltation and dredging has become unavoidable) ,ainl! silt dredged from the

La$e and used for the various purpose" hence retard siltation problem and at the same time

enhance other sectors) he ob4ective of this stud! #as to characterize ph!sical" chemical" and

bioremediation of the dredged material of Chil$a La$e) he geotechnical parameters li$e void

ratio" particle size anal!sis" specific gravit!" Atterberg5s limits" and compaction characteristics

studied from t#o different places in the La$e) his process of effective utilization of the dredged

material not onl! help in the reclamation of the La$e but also it save our natural resources) So

first dredging the soil from La$e and then utilizing it in a useful manner is an effective method to

deal #ith siltation problem)

t

Seismic performance of multi-storied buildings #ith

irregular distribution of mass" stiffness and strength along

the height" ma! be significantl! different and these

buildings suffer more damage compared to regular

buildings) All international Earth8ua$e design codes

suggest different methods of anal!sis for regular and

irregular buildings) (t is believed that the regular buildings

#ill have a dominant first mode and there are man!

procedures based on this fact to 8uantif! the irregularit! of buildings in terms of regularit! indices) (t is proposed to

stud! the correlation bet#een the vertical irregularit!

index and their performance in terms of probabilit! of

unacceptable behaviour for different vertical irregular

buildings selected as per the classification of ASCE-9) he

results sho#ed that the regularit! indices and the



reliabilit! indices are not #ell correlated)
