Murrum soil is the soil of humid tropical or equatorial zones. It is characterised by the deep weathered layer fom which silica has been leached. Thus, there is no humus, but an accumulation of aluminium and iron oxides and hydroxides. These soils are reddish in color & is imparted by the iron compounds. For building huts and paths, they are good materials, as it can be compacted easily to form hard surfaces.
Murrum soil comes under laterite soil. Laterite is a soil and a rock type rich in iron and aluminium. Murrum soil is also referred as being a rock type but it is not a rock.
The approximate density of murrum soil is 1.8 gm/cc.
Murrum is one type of laterite soil, which is red due to a higher amount of iron oxide. It is also rich in aluminum. Meaning of murrum is the disintegration of rock i.e., fragments of rock, that’s why it does not rock. Usually, shale or laterite rock is used in disintegration.
Murrum is practically used for filling work in case of road construction and in an embankment.
The density of murrum soil is 1.8 gm/cc.
Murrum soil is a one form of lateritic soil (Clayey material) which is used in road surface in Africa region. It is not a rock.
It is generally used in all over the world but major used in Africa region.
The murrum soil is reddish color of these soils is imparted compounds .they are good material for building huts and paths.as they compacted easily to form hard surfaces. They are generally impervious.
