International Conference on
An innovative material of fiber low-cement and cementless composite for building Industry

T
he carbon dioxide (CO
2
) emission during a manufacturing
process of the ordinary Portland cement is up to about 7.0
% of global manmade CO
2
. In order to improve the material
and mechanical characteristics of concrete and cement-based
material, an innovative near-environmental material of fiber-
reinforced low-cement and cementless composites has been
manufactured. The low-cement or cementless composites
were manufactured by replacing 60% of the amount of
cement with ground granulated blast-furnace slag with or
without using alkali activators or replacing with fly ash. Short
synthetic fibers were mixed in the composite binders in order
to improve the brittle tensile behaviour after cracks were
taken place. In the evaluation of the flow and mechanical
characteristics of the composites, a series of experiments
has been conducted on slump flow, compressive strength,
direct tensile strain, ductile bending, and shear strength test.
