WebbThe chemical composition of loess most often falls within the following percentage ranges: silica, SiO 2, 50 to 60; alumina, Al 2 O 3, 8 to 12; iron oxide as Fe 2 O 3, 2 to 4; iron oxide as FeO, 0.8 to 1.1; titanium dioxide, TiO 2, and manganese oxide, MnO, about 0.5; lime, CaO, 4 to 16; and magnesium oxide, MgO, 2 to 6.
WebbThe first property of soil is its structure, which refers to the way that soil particles are arranged and held together. Soil structure can range from loose and granular, to dense and compact. The structure of soil is influenced by a number of factors, including the type and size of soil particles, the amount of water present, and the presence of organic matter.
WebbAngular particles do not compact as readily as rounded particles because their angular surfaces tend to lock up with one another and resist compaction, while smoother, more rounded surfaces tend to pass by one another allowing for easier compaction. Therefore, the higher the measured uncompacted void content, the more angular the material.
