Concrete materials on the bump and spec progress. should get better when i am more familiar with the parameters but at the moment this should do.
Concrete
Concrete was used for construction in many ancient structures. Especially during the Roman Empire, it was a key event in the history of architecture.
Nowadays concrete is made mixing together various ingredients - water, aggregate, cement and etc. Ingredients should be properly mixed, placed, shaped, retained within time constraints. It has high compressive strength and low tensile strength. Low coefficient of thermal expansion and shrinks as it matures. It cracks to some extent due to shrinkage and tension. It can be damaged by the expansion of corrosion products of steel reinforcement bars, freezing of trapped water, fire or radiant heat, aggregate expansion, sea water effects, bacterial corrosion, leaching, erosion by fast-flowing water, physical damage and chemical damage from carbonatation, chlorides, sulfates and distillate water
Glass
Glass is hardly changed when it is left undisturbed at room temperature no matter how old it is. Stress and abrasion and affect and degrade glass, as well as water and extreme temperature.
Marble
Marble such as all calcareous rocks is particularly sensitive to degradation by acid chemicals and weathering. Acid rains are one of the main degradation reasons.
Calcium carbonate the main component of marble is not soluble in water.
The 50 word reflection of week2
Finding materials characteristics and its degradation status was fun. The materials for my chosen building are mainly concrete, marble and glass and a bit of woods. I sort of knew how concrete and woods would decay but it was interesting to see what marble and glass would be like when they degrade.
