Sub Disciplines
Transportation - design and operate highways, airports, railroads, and other forms of public transportation in order to ensure safety and efficiency
Structural - ensure that buildings and bridges are strong enough to withstand all kinds of stresses and strains
Environmental - plan projects that are essential to the health of people and aim to minimize the impact of human developments on the environment
Construction Management - designs, manages, and oversees projects within the construction industry
Geotechnical - includes, but is not limited to, construction and design of foundations, slopes, retaining structures, embankments, and other systems that are made or supported by soil and rock

Concrete is used frequently all around the world
Manufacturing concrete creates almost 10% of industrial greenhouse gas emissions
Concrete is made out of sand, water, gravel, and cement
Cement is made by heating a calcium-rich material with a silica-rich material, then grinding up the resulting “clinker” (hard mass)
Current industry standard: 1.7 calcium1 silicate
Magical ratio from study: 1.5 parts calcium to 1 part silicate
The new ratio makes concrete almost twice as strong/twice the resistance to breaking
More fracture-resistant due to disordered, glassy structure
Applications to the oil and gas industries
Use in housing - stronger houses for less material
Reductions in CO2 produced could be as much as 60%
Fairly recent study (September 2014), so not many impacts as of now
Research is still on the molecular level
Biggest problem the industry will have wit switching over is cost
Focus is on making material cost effective while retaining its new strength and lesser emissions
