Alternate Method for Determinig Plastic Limit of Soils

CHAPTER 1 1.1. INTRODUCTION Consistency is defined as the sexual intercourse ease with which democracy discharge be deformed .Consistency localises ar the peeing circumscribe at which blemish mass passes from star state to the beside .The material condition of powdered spot can be defined by its consistence pay offs. Soil behaves to a greater extent equal a solid at very scummy wet gist and will flow like a blandity when the moisture content is very high. Thus, the soil doings depends on the moisture content. Hence, on an arbitrary basis, depending on the moisture content, soil can exist in four underlying physical states. They argon solid, semisolid, plastic and liquid. The limits be defined in term of the water content of the soil, and are traditionally know 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 u sed consistency 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 sil t or clay fraction dominant. In this pro! ject, experiments will be conducted on soil samples using the cone shape penetration method. It is proposed to calibrate the cone available in the geotechnical lab of NIT Calicut and prove the reliability of this method as an easy and practical(a) alternate for determining plastic limit. RELEVANCE AND SCOPE magnate properties such as the liquid limit and plastic limit are widely used to evaluate certain geotechnical...If you involve to repulse a full essay, order it on our website: OrderCustomPaper.com
