One of the main uses of laterites for construction purposes is the production of Compressed Earth Blocks (CEB). It is full of cavities and pores, and contains a large quantity of iron in the form of red and yellow ochres. The first two categories can be distinguished by their plasticity characteristics. Lateritic soils abound in virtually all parts of the tropical world. Provision of low-cost access track. Concretionary laterite is widely used as a sub-base and base material for gravel roads but, owing to confusion of terminology, the application of lateritic materials is frequently misunderstood. Myrvin George, a 44-year-old engineer of Victoria Avenue, Eccles . Sand, Laterite and Granite. This document discusses advantages and disadvantages of gravel road surfacing, offers design considerations and suggestions, and gives general guidelines for road construction and maintenance. Laterite is a source of iron ore. High content of iron oxide and alumina are found in Laterite. How ever, not all laterite soils belong to this group. The mechanical strength of a fine-grained lateritic soil treated with CEMII/BM 32.5 N cement up to 9% by weight of dry soil and prepared at three different molding water contents was investigated by means of California bearing ratio (CBR), unconfined compressive strength (UCS), indirect tensile strength (TS), and triaxial shear tests. Dear Editor, I was fortunate to recently visit the road construction work ongoing at the Takutu Bridge and also over in Bom Fin, Brazil. It is diffused in immense masses, without any appearance of stratification and is placed over the granite that forms the basis of Malayala. : 4 The reaction zone where rocks are in contact with water—from the lowest to highest water table levels—is progressively depleted of the easily leached ions of sodium, potassium, calcium and magnesium.
