Concrete is a versatile and durable building material that has been used for centuries to construct roads, fale, alalaupapa, ma isi fausaga. Despite its popularity, some people argue that concrete is not actually a mineral.
(Ole Sima ole Minerale)
The term “mineral” typically refers to a substance that is formed by chemical reactions between elements in the Earth’s crust. This can include things like minerals such as gold, silver, and quartz, as well as non-minerals such as sand, iliili, and clay.
Peitai, when we talk about concrete, it is actually made from a mixture of cement, vai, ma fa'atasi (such as sand or crushed stone). While these ingredients may contain some form of mineral, they do not make up all of the material. Ae o le mea moni, much of the concrete used today is produced using an industrial process that does not involve chemical reactions at all.
To put this into perspective, let’s take a look at what makes up the three most common types of cement: Portland sima, which is widely used for construction; calcium carbonate cement (CaCO3), which is commonly used in marine engineering applications; and fly ash cement, which is made from ash waste from power plants.
Each of these types of cement contains different minerals, e aofia ai le lime, magnesium sulfate, and titanium dioxide, faatasi ai ma isi. Peitai, the actual makeup of each type of cement varies depending on the specific recipe and the location where it is produced.
So while there may be some minerals present in the concrete that are typically referred to as “minerals,” it is important to note that the process of making concrete does not involve any chemical reactions that would result in the formation of minerals.
