They are structural clay products, manufactured as standard units, used in building construction
Brick and tile
20
It is a mixture of paste and aggregates. The paste,composed of Portland Cement and water, coats the surface of the fine and coarse aggregates.Through a chemical reaction called hydration,the paste hardens and gains strength to form the rock
Cement concrete
15
It constitutes the primary material for the foundation, subgrade, or even the pavement (for low-cost roads with low traffic in rural areas)
Soil
20
It is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants
Wood
15
A concrete mixture which has high workability, high strength, high modulus of physical property, high density, high dimensional stability, low permeability and resistance to chemical attack
Ultra-high performance concrete
25
It is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits.
Polymer
15
It is a broad category of coarse- to medium-grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates
Aggregate
10
It has Dense, highly viscous, petroleum-based hydrocarbon that is found in deposits such as oil sands and pitch lakes (natural bitumen) or is obtained as a residue of the distillation of crude oil (refined bitumen).
Bitumen
20
the degree to which a specified material conducts electricity, calculated as the ratio of the current density in the material to the electric field which causes the flow of current.
Conductivity
20
a line on the surface of something along which it has split without breaking apart
Crack
15
a wall supported by a steel or concrete structure of a building. A curtain wall does not have any support functions itself, as does bearing wall
Curtain wall
20
building materials such as rock, brick, or tile, often bound together by mortar or cement
Masonry
25
They are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides
Retaining walls
15
the process of fastening together pieces of metal with rivets that do not have threads
Riveting
20
They are used to join pieces of wood, mainly when the adjoining pieces connect at an angle of 90°
Mortise/mortice and tenon
15
the process of fastening together pieces of metal by melting a bonding metal between similar metals
