• SALOMONE REDI-MIX

• SERVICE CONCRETE CO.

• SILVI CONCRETE

• SUFFOLK REDI MIX

• WELDON CONCRETE

• common generic term for this material: concrete

• some material application:

• sidewalks

• parking structures

• dams

• pools

• foundations

• walls

• intended/primary use:

• cast-in-place concrete has a wide range of common uses

• cast-in-place concrete is primarily used for structure and infrastructure

• list any emerging or innovative material applications:

• cast-in-place concrete facade

• organic shapes

• physical properties:

• strong in compression

• week in tension (rebar is often used to improved

tension strath)

! Truszkowski �3

• finish:

• the aggregate used can effect the finish

• wether can effect how dark cast-in-place concrete is

• holes from ties that held the form will need to be filled

• can be polished or stained

• surface forms/shapes: cast-in-place concrete can have various textures and shapes

depending on how it was molded and what design mix was used

! Truszkowski �4

• dimensions (Height, Width, Depth): cast-in-place concrete

is molded it can have numerous dimensions

• weight:

• most concrete mixtures are about 150 pounds per cubic

foot it depends on the design mix

• acoustic properties: the mass of concrete reduces the transmission of sound

• structural properties:

• strong in compression

• week in tension (rebar is often used to

improved tension strath)

• primary structure, secondary structure:

concrete can be used for most structural

components

• non-structural: a sculptural material that can be molded

• installation methods:

• cast-in-place concrete is molded using forms in place on site opposed to precast

concrete

• forms can be metal or wood and they can have different textures or no textures

• Cost analysis: cost will vary depending on design mix ingredients and quantity

• price: most concrete costs between $120 and $150 per cubic yard

• material background: In 3000 BC Romans used lime and volcanic ash called

pozzuolana as an early form of concrete

! Truszkowski �5

• how concrete is made: concrete is made by mixing precise amounts of water,

cement, aggregate and possibly Admixtures

• What are its components and where do those components come from? Concrete is

made of water, cement and aggregate. Aggregate may be natural however recycled

aggregates from construction, demolition and excavation waste are increasingly

being used.

• what is the process to make the material? Concrete is made by mixing precise

amounts of water, cement, aggregate and possibly Admixtures.

! Truszkowski �6

• harvesting/manufacturing process: Aggregate may be natural however recycled

aggregates from construction, demolition and excavation waste are increasingly

being used.

• What are the byproducts of the process? Carbon dioxide os a byproduct currently

however efforts are being made to make concrete a more sustainable material.

• environmental impact:

• large contributor of carbon dioxide emissions

• can cause erosion due to run off

• concrete dust causes dangerous air pollution

• expected life expectancy in a commercial application:

• concrete frame life expectancy is 81 years

• reinforced concrete floor life expectancy is 71 years

• maintenance requirements: concrete will crack and those cracks may need to be

repaired

• recycling: concrete can be recycled into aggregate
