Concrete is made of cement and gravel, which is why this subgrade form places a special requirement on the bolt anchor.
The efficiency of the anchors depends on the respective compressive strength of the concrete.
The most common concrete grade is C20 / 25, which states a compressive strength of 25 N / mm2.
Brickwork consists of individual brick layers and is held together with mortar.
The brick walls can consist of hollow or solid bricks, which also depends on the selection of the appropriate anchor bolt.
Block walls are built from individual blocks and connected with mortar
Block walls can be built either with hollow or solid blocks
The choice of bolts largely depends on whether the blocks are hollow or full
