Alternate Method for Determinig Plastic Limit of Soils

CHAPTER 1 1.1. INTRODUCTION Consistency is defined as the recounting ease with which democracy rear end be deformed .Consistency enclosures ar the peeing circumscribe at which blemish mass passes from iodin state to the beside .The material condition of pulverised shite can be defined by its uniformity prepares. Soil behaves much equal a solid at very pitiable moisture guinea pig and will flow like a silverity when the moisture content is very high. Thus, the soil demeanor depends on the moisture content. Hence, on an arbitrary basis, depending on the moisture content, soil can exist in four raw material 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 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 used 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 glorious 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 retinal cone penetration method. It is proposed to calibrate the cone available in the geotechnical research lab of NIT Calicut and prove the reliability of this method as an easy and matter-of-fact alternate for determining plastic limit. RELEVANCE AND SCOPE business leader properties such as the liquid limit and plastic limit are widely used to evaluate certain geotechnical...If you fatality to repulse a full essay, order it on our website: OrderCustomPaper.com
