Three materials properties

 Concrete

 

Properies 

Concrete is a composite construction material composed primarily of aggregate, cement, and water.

Concrete is widely used for making architectural structures, foundations, brick  walls, pavements, bridges, motorways, runways, parking structures, dams, reservoirs, pipes, footings for gates, fences and poles and even boats.

Concrete has relatively high compressive strength, but much lower tensile strength. For this reason it is usually reinforced with materials that are strong in tension. Concrete can be damaged by many processes, such as the freezing pf trapped water.

Environment Impact

The environmental impact of concrete is a complex mixture of not entirely negative effects:  while concrete is a major contributor to greenhouse gas emissions, recycling of concrete is increasingly common in structures that have reached the end of their life. Structures made of concrete can have a long service life. As concrete has a high thermal mass and very low permeability, it can make for energy efficient housing.

Marble

 Properties  

Marble -- formed from limestone with heat and pressure over years in the earth's crust. These pressure or forces cause the limestone to change in texture and makeup. The process is called recrystallization. Fossilized materials in the limestone, along with its original carbonate minerals, recrystallize and form large, coarse grains of calcite.Crushed or ground marble is also used in paving roads and in manufacturing roofing materials and soil treatment products.

Construction marble is a stone which is composed of calcite, dolomite or serpentine which is capable of taking a polish. More generally in construction, specifically the dimension stone trade, the term "marble" is used for any crystalline calcitic rock useful as building stone. For example, Tennessee marble is really a dense granular fossiliferous gray to pink to maroon Ordovician limestone that geologists call the Holston Formation.

 

Brick

 

Properties

Bricks are used for building, block paving and pavement. Modern clay bricks are formed in one of three processes - soft mud, dry press, or extruded. Normally, brick contains the ingredients: Sand, Clay, Lime, Iron oxide and Magnesia.

A brick's compressive strength is based on its solidness or hollowness, its base material and the method is used to fire the raw materials into their final consistency. When bricks with a high compressive strength are used to build a structure, that structure will be very strong because of the quality of the materials.
