Kimberlite
Kimberlite is an igneous rock which sometimes contains is named after the town of Kimberley in South Africa where the discovery of an carat g diamond called the Star of South Africa in 1869 spawned a diamond rush and the digging of the open pit mine called the Big the term kimberlite has been applied to olivine lamproites as Kimberlite II however
Effects of basalt fiber in lightweight expanded clay
The percentages lengths and diameters of chopped basalt fiber in concrete mixture have high influence on concrete strength On the other hand expanded clay contributes mostly in the weight reduction of the concrete hereby giving what is called lightweight concrete The collapse of concrete structures can be blamed to the effect of cracks that are born in the weak concrete structures.
