| description | This study analyzes the feasibility of valorizing industrial by-product, fly
ash from a thermal power plant as a partial replacement of mineral
filler-limestone for the production of self-compacting concrete (SCC). Three
types of SCC mixtures with different portions of fly ash and the reference
mixture with limestone were designed. The synthesized SCCs in the fresh
state were examined for density, entrained air content, flowability (Slump
flow, Slump flow time (t500), V-funnel time (tv)), passing ability (L-box),
and segregation resistance, while hardened state testing included: density,
compressive and flexural strength, static modulus of elasticity, water
permeability, resistance against freezing in the presence of de-icing salt,
and SEM analysis. Taking into account the obtained results it can be
concluded that the addition of fly ash has a positive impact on the concrete
properties and that the optimal content of fly ash is 20 % with respect to
the total filler mass. |
