Concrete Reinforcement

Concrete is strong in compression, however is generally weak in tension. Therefore when a load is placed upon it it may bend. To make sure this doesn’t happen, steel reinforcement is put in on the tensile face, normally the bottom edge if a floor or beam.
Tension can also occur outwards, so for example a basement [...]

Characteristics of Stone – Advantages and Disadvantages

Advantages

Good compressive strength
Familiar material to workforce
Ethnic – of the locality

Disadvantages

Poor tensile strength
Some stones decay
Need for skilled workforce
Maintenance cost – discolouration/cleaning
Sedimentary stone is not formed under pressure but in layers and can split off if vertically loaded. This can, however, be useful – eg slate
Some stone, such as marble, is too expensive for construction although may [...]
