Water damage was common in the early days of construction for the building. To stop the water damage, workers covered the sandstone in a mixture of salt, rice, and glue, which help to give the White House its distinctive white color. Lithification—Sediments to Sedimentary rocks

As a common porous medium composed of a framework of grains and void spaces, sandstone is often found in projects, such as water conservancy and hydropower, carbon dioxide geological storage, underground mining, and tight sandstone gas reservoirs (Pettijohn et al. 1972; Xu et al. 2018; Geologists, American Association of Petroleum …

On the other hand, porosity is clearly a key parameter in sandstone strength (Jeng, et al2004, Hsieh et al2008) in that pores reduce the integrity of the rock.Field tests show that CO 2 flooding is a potential option to improve the oil recovery of low-permeability sandstone reservoirs (Zekri et ... presented the results of an experimental study on immiscible CO 2 flooding efficiency in sandstone porous media, but their research did not involve microscale investigation and they focused on the ...On the other hand, porosity is clearly a key parameter in sandstone strength (Jeng, et al2004, Hsieh et al2008) in that pores reduce the integrity of the rock.Sandstone: Fine-grained rocks such as sandstone make good aquifers.
