Actually, the unsoundness of concrete made with such aggregate is due to coals' expansion on wetting and contraction on drying. Foamed Slag: Foamed slag is such type of light weight aggregate which is a byproduct of quenching blast furnace slag as produce by the manufacturing of pig iron.
One way is to incorporate a lightweight aggregate. Natural lightweight aggregates such as pumice [most widely used], scoria, volcanic cinders, tuff and diatomite. Or artificial aggregates or rotary kiln produced lightweight aggregates such as expanded clays, slates, slag, perlite or shale's. Cenospheres
common terms such as clay loam, sandy loam, and silty clay loam. The textural class of a soil directly affects water-holding capacity, water movement, aeration or porosity, bonding of soil particles into stable aggregates, soil micro-organisms, root growth, and soil temperature dynamics. Stones, cobbles, and gravel are larger than

Aggregate is the component of a composite material that resists compressive stress and provides bulk to the composite material. For efficient filling, aggregate should be much smaller than the finished item, but have a wide variety of sizes. For example, the particles of stone used to make concrete typically include both sand and gravel

A soil moisture content of 150 mm/m. The soil moisture content can also be expressed in percent of volume. In the example above, 1 m 3 of soil (e.g. with a depth of 1 m, and a surface area of 1 m 2) contains 0.150 m 3 of water (e.g. with a depth of 150 mm = 0.150 m and a surface area of 1 m 2 ). This results in a soil moisture content in volume ...
Environmental characteristics include the nature and distribution of inorganic contaminants, such as metals and metalloids like arsenic, iron, and lead, in clay-bearing rocks. These environmental factors have the potential to affect the use of clays in natural and industrial applications. --NORA K. FOLEY.
Expanded clay is a lightweight aggregate produced industrially whose fea-tures may be modified to optimize the performance of the aggregate with very different uses. It is possible to obtain: • lightweight insulating grout with open structure:concrete aggregates with open structure and density between 600 and 1000 kg/m3;
