The aggregates that form artificial stone may be composed of- pieces of marble, crushed granite, quartz sand, glass crystals, and other components that are aggregated with bonds agents such as epoxy resin 8. Several studies have shown that size of the particles influence the mechanical properties.

Live ChatTypically, the mitigation of coastal erosion is achieved by amending surface conditions using materials, such as concrete. The objective of this study is to evaluate the feasibility of constructing artificial beachrocks using natural materials e.g., microbes, sand, shell, pieces of coral, and seaweed, etc. within a short time, and to propose the method as a novel strategy for coastal protection.
Live Chat2014-12-30Natural aggregates, such as those mentioned, give concrete certain physical, chemical, and mechanical properties. However, as a result of environmental concerns, there has been a growing trend for the use of recycled plastic waste as artificial aggregate instead of natural aggregate in the production of concrete.
