This study assessed the dispersivity of soils extracted from northern region Cartagena de Indias (Colombia) using pinhole test, crumb and chemical–microstructural analyses. Dispersive are susceptible to erosive phenomena upon contact with water, yet they have not been adequately characterized in city. To evaluate degree different deformed undisturbed soil samples, characterization tests include...

Peat soils are organic formed from decomposed plant parts that spread throughout the world, reaching 423 million hectares. It is well known peat have adverse characteristics for infrastructure development due to their low shear strength and durability. Therefore, a lot of research has been done regarding improvement so in dominant soil locations. However, conducting research, many tests were fo...

Abstract A polymer-enhanced bentonite-sand mixture has been widely used as a clay liner. This research focuses on the potential use of chitosan natural polymer mixed with bentonite liner base material. The is type calcium bentonite, which easily obtained in market. Meanwhile, produced from shrimp shell waste and also available process mixing percentage 2–6% was carried out using certain method,...

In Nigeria, potassium permanganate (KMnO4) is used as a chemical oxidant in the removal of hydrocarbons from polluted soils and groundwater, but there no information on effects KMnO4 geotechnical properties soil. this study, was added separately to lateritic soil kaolin at concentrations 0 %, 2 5% 10 % by weight dry Each mixes then subjected grain size analysis, Atterberg limits, specific gravi...

The presence of gypsum in soil has a high effect on the mechanical and physical properties soil. This depends fundamentally type quantity existent present study attempts to improve gypseous using new pozzolanic material discovered as from attapulgite clay. It is called “High Reactivity Attapulgite” HRA. objective this investigate ability be moderate stabilizer used for treating was obtained one...

Volume change of expansive soils is a challenging issue, which affects various engineering structures all over the world. Consequently, we need environmentally-friendly and cost-effective soil stabilizers to address challenges related soils. The utilization natural fibers allows for reduction in environmental impact since they are renewable biodegradable raw materials. Moreover, current article...

Abstract The liquefaction event that occurred in Petobo Village, Palu City, Central Sulawesi, was caused by the earthquake on September 28 th , 2018 with a magnitude of 7.4 and depth 10 km. This study aims to determine characteristics soil also whether area still has potential for based Test Swedish Weight Sounding (SWS) Cone Penetration (CPT) . test is carried out at location limit cessation l...

High price of land and importance modern construction has imposed the need to strengthen weak clay soils. The stabilization these soils been conducted using various additives. Due its low cost, availability, positive impact on resistance, lime traditionally applied for stabilisation poor sensitive types In this research, powder, added in percentages 0, 2, 4, 8 16 dry soil weight, was mixed with...

Lime stabilization is one of the techniques that can be used for improving the engineering properties, particularly the strength, of soft clays. This paper aims to investigate the effect of hydrated lime on the strength and microstructure of lime treated clays. In order to illustrate such effect, a series of laboratory tests were conducted. Atterberg limits, compaction tests, unconfined compres...
