Concrete mixtures are normally poured in single layers without intentional changes in the mixture properties within the thickness of the layers.
In this research paper, alternative approach is introduced with Functionally Layered Concrete (FLC) composites, which have their known functions to achieve the maximum performance index.
The performance index can be defined as the ratio of characteristics to the consumption of resources, fibres and additives. The steel fibre, polypropylene fibre, and silica fume are used in cement composites to make multilayer samples on which mechanical properties evaluations are conducted and compared to that of Mono-Layered Concrete (MLC) samples.
It is observed from the results that FLC samples have superior mechanical characteristics compared to MLC samples in terms of compressive strength, flexural strength and elastic modulus.
Given that the use of fibres/additives in FLC composites is diminished, acquiring better mechanical performance with minimised consumption of resources would be possible via functionally layered composite method.
