Is fracture a cleavage?
Summary: Cleavage and fracture are two defining characteristics of minerals studied by geologists. Cleavage is the way a break happens along a weak plane of the mineral, and fracture is the way a break happens along a strong plane of the mineral.
Do rocks have cleavage and fracture?
Mineral does not exhibit cleavage, it breaks or fracture in an irregular manner.

What is an example of fracture?
Growing bones tend to buckle or bend before breaking, which often leads to unique fracture patterns. For instance, one side of a bone may bend, causing a greenstick (bending) fracture. Or one side of the bone can buckle and become dented, causing a buckle fracture.
What are the types of brick foundation damage?
Damage caused to brick structures due to thermal expansion of long brick walls lacking expansion joints. Damage to brick veneer walls – cracks, bulges, loose brick. A catalog of types of brick foundation and brick wall damage and defects. Types of foundation damage organized by foundation materials.
What could have caused this brick wall to collapse?
We can see that this collapsed brick wall was a structural brick foundation, and the soil piled up suggests it was done in by pressure from wet earth – a drainage or roof drainage problem may have been the root cause of this collapse.
What damage can caulking do to a brick building?
We inspected a Manhattan apartment building which suffered multi-million damage to its brick exterior after a new “super” insisted on caulking tightly all of the steel window lintels. We also see rust-damaged brick walls when leaks into the brick structure cause rusting of steel wire, mesh, or re-bar reinforcement.
What are normal Expansion cracks in brick walls?
THERMAL EXPANSION CRACKS in BRICK, usually diagonal or stair-stepped, often at building corners where roof spillage is concentrated. Our photo (above) of step cracks in a structural brick wall also shows that the upper section of the wall has bulged outwards past the lower or right hand section of this structure.
