GENERAL KNOWLEDGE

Detailed explanation-1: -The name of the soil Laterite is based on the Latin ‘Later, ‘ meaning brick. When moist, the laterite soil is as smooth as butter; however, they become rigid and clumpy when dry. As a result, they are commonly cut into bricks to be used in house construction. Owing to the existence of iron oxide, these soils are red.

Detailed explanation-2: -Laterite Soil has been obtained abundantly in tropical regions and this soil encompasses of good strength when compared to other soil. This soil is ironic in alumina and iron formed in hot and wet tropical areas. Thus, Laterite soil can be used as a building material for the manufacturing of bricks.

Detailed explanation-3: -Laterite soils are widely cut as bricks for use in house construction. These soils have mainly developed in the higher areas of the peninsular plateau.

Detailed explanation-4: -Laterite bricks were manufactured with mix proportion of 2.5% of cement and 3% of Rice Husk by the weight of soil. The proportion of laterite was progressively replaced with fly ash thereby having unlike mix proportions of 2.5%, 5%, 7.5% by weight of soil while keeping the quantity of cement and rice husk constant.
