The term 'laterite' and the process 'laterization'—both have raised perpetual scientific debates. The present study reviews the relevant scientific pieces of literature associated with tropical red lateritic and ferralitic soils and tries to justify them with the observations in the Paschim Medinipur Lateritic Upland. This particular area is practically …

laterite, soil layer that is rich in iron oxide and derived from a wide variety of rocks weathering under strongly oxidizing and leaching conditions. It forms in tropical and subtropical regions where the climate is humid. Lateritic soils may contain clay minerals; but they tend to be silica-poor, for silica is leached out by waters passing through the soil.
The chemical analysis of laterite soil samples sourced from literature, Table 1 showed that the major compounds present in the laterite soil are SiO 2, Al 2 O 3, and Fe 2 O 3.These compounds were predominantly more than 70% of total composition of oxide …
Lateritic soils are formed in the tropics through weathering processes that favor the formation of iron, aluminum, manganese and titanium oxides. These processes break down silicate minerals into clay …
Laterite Profile—Laterite profiles are a vertical sequence of regolith facies showing some or all of the following, from the bottom-up: bedrock, saprock, saprolite, plasmic zone, mottled zone or ferruginous saprolite, lateritic residuum (Fig. 1.4). The successive zones of the laterite profile are separated by more or less clearly ...

From the magnificent red and yellow potmarked temples of Cambodia to the durable smooth roads of Gabon, laterite is a stone of a thousand uses. Many are well known to the modern engineer—yet many still lie buried beneath green vines, shifted sands, or cracked stucco. Download to read the full chapter text.

Portland cement is the primary material in the field of construction. Despite its importance, its production remains an energy-consuming and polluting operation. Research on alternatives to Portland cement has become an international concern, and these alternatives include geopolymers. With the evolution of the research on …
Laterite stone construction is cost effective as the volume of laterite stone (390 mm × 190 mm × 190 mm) is nearly nine times higher than the volume of the burnt clay bricks (190 mm × 90 mm × 90 mm). ... Enhanced thermal mass is responsible for the reduced decrement factors and improved time lag values. Download : Download full-size …
There are several laterite stone quarries in Konkan region. During excavation of laterite stone, around 25 % – 30 % lateritic stone scrap is generated. It is estimated that about 2.83 3 cum (100 ...

Lateritic building stones (LBS) from Burkina-Faso are studied for their hygroscopic, physical and mechanical characteristics by conducting experimental …
Laterite has been widely used as construction material in southeast Asia throughout history. Examples of monumental buildings are the Angkor Wat temple in Cambodia (twelfth century) where it was used as a core for walls, covered by limestone, the temples of Ayutthaia in Thailand (fourteenth to sixteenth century) and large colonial …
