| Summary: | Concrete is the most used construction material because it’s durability, strength,
and workability but also has a large contribution to the world CO? emission that comes from
cement manufacturing process during calcination. Scientist and engineer discovered that a
“greener” replacement can be done to minimize CO? emission called as “Green” concrete.
Green concrete is widely used nowadays to minimize emissions but there still pros and cons
regarding its usage; therefore, a literature research can be done regarding green concrete as
solution for concrete environmental problems by using TRIZ method.
Green concrete still also has its disadvantages to replace conventional concrete.
Disadvantages such as concrete life and strength are a crucial consideration in construction
process. TRIZ as a knowledge based problem-solving method that provides tools needed
to innovate by overcoming innovation problems such as psychological inertia and
contradiction. Tools that are used for this research are Root Conflict Analysis (RCA+) and
contradiction matrix. These tools will provide problem understanding and discover
contradiction in innovating while also suggested inventive principles to overcome
contradictions. Finding the suitable inventive principle is done by examining each one of
the suggested principles then match with concrete theory.
Green concrete is a suitable replacement for conventional concrete according to
this literature research. Replacement such as fly ash, rice husk ash, and silica fume can be
added to reduce cement usage which will reduce CO? emission by approximately 30%.
However, there are limitation for each replacement that needs attention to preserve concrete
mechanical properties |
