CHAPTER 1: INTRODUCTION1.1 Overview of the study Clay perviousness is said to be dependent on list of factors including addition of sand.The research proposed herewith emphasizes on evaluating the quality parameters of clay. Theresearch work emphasizes on identifying if the sand act as an additive substance for determiningpermeability of clay. It is through in-depth research that the researcher strives to identify whethersand helps in stabilizing the swelling clay soils. Sand are the particles ranging in sizes of 2mm - 0.02mm basically shaped due to theweathering of rocks parts of tremor. Sand has small surface areas and does not hold much waterbecause of low permeability factor while the clay particles differ from the sand particles in that itis composed predominantly of minerals arranged as products of secondary weathering, i.e.: therock minerals undergo alteration before becoming clay minerals.Permeability is observed as a standout amongst the most critical parameters in soilmechanics. Fundamentally, it is characterized by the amount of water going through a claymedium in a specific period, and is controlled by in-situ and research center tests. In basicpractice, the porousness coefficient is normally gotten by constant head penetrability test, and isused in filtration-seepage, settlement, and solidness computations.[1]Clay in the form of mud is the oldest binding material for the buildings which mayinclude houses and other construction elements. Mud is available cheap and strong bindingmaterial and with no heavy technical staff or machinery. In Egypt the grain stores of Ramasseumbuilt in adobe in 1300BC still exist; the Great Wall of China has sections built in rammedearth over 2000 years ago. Iran, India, Nepal, Yemen all have examples of ancient citiesand large buildings built in various forms of earthen construction. The strength ofunsterilized earth walls comes from the bonding effect of dried clay. If this becomes wet thestrength is lost and indeed the wall will erode or even fail completely. The water retentioncharacteristics are controlled by the sand and soil mixture so it is a basic point of control to retainthe mixture of the clay and sand to get effective results.[2, 3]Sandy Clay Loam can bear 20-30 %of the clay content with the field capacity of 2.3 mm/cm of soil, wilting point of 1.3 mm/cm ofsoil and available water of 1.5 mm/cm of soil.[4]Page 2 of 8
