kivennäismateriaaliksi

Kivennäismateriaali, often translated as mineral material or aggregate, refers to naturally occurring or manufactured granular materials used in construction and other industrial applications. This broad category encompasses a wide range of substances, including sand, gravel, crushed stone, slag, and recycled concrete. The specific type and quality of kivennäismateriaali used depend heavily on its intended application.

In construction, kivennäismateriaali is a fundamental component of many building materials. It forms the bulk of concrete, providing strength and volume. It is also essential for asphalt, used in road construction, where it binds with bitumen to create a durable surface. Furthermore, kivennäismateriaali is used as fill material in embankments and foundations, and as a base layer for roads and railways. Its granular nature allows for good drainage and stability.

The production of kivennäismateriaali involves extraction from quarries or riverbeds, followed by processes like crushing, screening, and washing to achieve the desired particle size and shape. The properties of kivennäismateriaali, such as its grain size distribution, shape, hardness, and cleanliness, are critical for its performance in its intended use. Environmental considerations, including responsible sourcing and potential impacts of extraction, are increasingly important in the management of kivennäismateriaali resources.
