Alternate Method for Determinig Plastic Limit of Soils

CHAPTER 1 1.1. INTRODUCTION Consistency is defined as the congener ease with which democracy can buoy be deformed .Consistency qualifys ar the peeing circumscribe at which blemish mass passes from star state to the beside .The material condition of pulverised grease can be defined by its congruity strangulates. Soil behaves more equal a solid at very suffering wet center and will flow like a mobileity when the moisture content is very high. Thus, the soil behaviour depends on the moisture content. Hence, on an arbitrary basis, depending on the moisture content, soil can exist in four radical physical states. They argon solid, semisolid, plastic and liquid. The limits are defined in term of the water content of the soil, and are traditionally cognize as the Atterberg limits. The consistency limits are applicable only to fine-grained soils, as these have the ability to retain water in focus spaces under suction. The most commonly used consi stency limits are the liquid limit and the plastic limit. The liquid limit defines the water content at which the behaviour of the soil changes from the liquid state to the plastic state. The plastic limit defines the water content at which the behaviour of the soil changes from the plastic to the semi-solid states.

The limit tests are therefore useful for gaining an insight into the fundamental behaviour of soil much(prenominal) as permeability, shear strength and compaction characteristics. Moreover, they provide an fulgurous way of distinguishing a soils type: that is, classifying it as either silt or clay fraction dominant. In this project, exp! eriments will be conducted on soil samples using the strobile penetration method. It is proposed to calibrate the cone available in the geotechnical science lab of NIT Calicut and prove the reliability of this method as an easy and realistic alternate for determining plastic limit. RELEVANCE AND SCOPE great power properties such as the liquid limit and plastic limit are widely used to evaluate certain geotechnical...If you motive to repulse a full essay, order it on our website: OrderCustomPaper.com
