Various soil texture schemes are in current use. These differ in the size ranges of their particle fractions. There is a need to establish simple methods to correlate these conventional schemes. Therefore I have defined closed-form exponential and power law functions to fit models to cumulative particle-size distribution data. I have tested the functions for their suitability (i) to represent c...

Abstract Construction and demolition wastes (CDW) are a concern in urban areas, addition, it is well understood that soft soils inappropriate for paving designs. Therefore, this paper presents an alternative solution combining CDW silty soil, aiming to overcome the soil drawbacks by repeated loadings. For purpose, laboratory study was developed, comprising both resilient modulus (M R ) unconfin...

classical soil mechanics involves the study of fully saturated soils. however, many problems encountered in geotechnical engineering practice involve unsaturated soil, in which behavior is significantly different from classical saturated soil. negative pore pressure and capillary forces develop a virtual cohesion between the grains of semi saturated soils. this kind of cohesion is dependent on ...

In this paper a laboratory study has been carried out on the effect of changing the type of soil filling cylindrical reinforcing elements from SM to GM on behavior of sandy soil. In this study the primary tests for evaluation of the impact of reinforced sand and gravel columns with diameters of 5 cm and heights of 15 cm subjected to vertical stresses of 50, 100, and 150 KPa were carried out in ...

Colic (abdominal pain), caused from the accumulation of sand and small pieces of gravel in the large colon, continues to be a problem for horses. In one study, of the cases of colic with an identifiable cause, 5% of the reported colic cases were due to sand. This was greater than those caused by gas (3%), mesenteric arteritis caused by small strongyles (1%), and ingestion of moldy grain (1%). I...

The soil resources of Sierra Leone remain an integral part sustainable agricultural development but knowledge the suitability soils and their management requirements for a variety land uses is still lacking to greater extent. In this view, detailed survey three chiefdoms in Northern was undertaken evaluate genesis interpret soil-landscape properties relationships using toposequence free style a...
