What is the ratio of the building material that is named for the Latin word "crushed" and sand used to stabilize buildings?
Sandcrete Sandcrete is a yellow-white building material made from a binder (typically Portland cement), sand in a ratio of circa 1:8, and water. Sometimes other ingredients may be added to reduce the amount of expensive Portland cement such as pozzolanas and rice husk ash. Sandcrete is similar but weaker than mortar, for which the ratio is circa 1:5. "Soil cement" and "landcrete" are similar materials but use other types of soil and hydraform blocks which are compressed, stabilized, earth blocks.
Wackestone Under the Dunham classification (Dunham, 1962) system of limestones, a wackestone is defined as a mud-supported carbonate rock that contains greater than 10% grains. Most recently, this definition has been clarified as "a carbonate-dominated rock in which the carbonate mud (2 mm)".
