Behaviour of gneiss and basalt aggregate in normal …
This work aims at analyzing the high temperature behaviour of normal concrete containing quarry aggregates commonly used in Cameroon. Gneiss aggregate concrete (C-SG-GG) and basalt aggregate concrete (C-SB-GB) were formulated. Specimens were subjected to different heating–cooling cycles of 150, 300, 450 and 600 …

Basalt | Properties, Formation, Composition, Uses
Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.
