OVERVIEW Elastic Composite Reinforced Lightweight Concrete; ECRLC as a Type of Resilient Composite Systems; RCS [Hidden Content] - ABSTRACT - A kind of "Elastic Composite, Reinforced Lightweight Concrete (ECRLC)" with the mentioned specifics is a type of "Resilient Composite Systems (RCS)" in which, contrary to the basic geometrical assumption of flexure theory in Solid Mechanics, "the strain changes in the beam height during bending" is typically "Non-linear". i Through employing this integrated structure, with significant high strain capability and modulus of resilience in bending, we could constructively achieve high bearing capacities in beams with secure fracture pattern, in less weight. i Due to the system particulars and its behavior in bending, the usual calculation of the equilibrium steel amount to attain the low-steel bending sections with secure fracture pattern in the beams and its related limitations do not become propounded. Thereby, the strategic deadlock of high possibility of brittle fracture pattern in the bending elements made of the usual reinforced lightweight concretes, especially about the low-thickness bending elements as slabs, is being unlocked. i This simple, applied technology and the related components and systems can have several applications in "the Road and Building Industries" too. i Regarding the "strategic importance of the Lightweight & Integrated Construction in practical increase of the resistance and safety against earthquake" and considering the appropriate behavior of this resilient structure against the dynamic loads, shakes, impacts and shocks and capability of making some lightweight and insulating, non-brittle, reinforced sandwich panels and pieces, this system and its components could be also useful in "seismic areas". i This system could be also employed in constructing the vibration and impact absorber bearing pieces and slabs, which can be used in "the Railroad & Subway Structures" too. i In the relevant paper, the "Resilient Composite Systems (RCS)" and particularly, "Elastic Composite, Reinforced Lightweight Concrete (ECRLC)" as a type of RCS have been concisely presented. [Meanwhile, in the related pictures & figures, an instance of the said new structure and its components and the results of some performed experiments (as the "in-bending" & in-compressive loadings of the slabs including this structure, similar to ASTM E 72 Standard) have been pointed.] i .

FINAL REVIEW ACKNOWLEDGEMENTS REFERENCES *** - General Review - A kind of "Elastic Composite, Reinforced Lightweight Concrete" with the said specifics is a type of the "Resilient Composite Systems (R.C.S.)" in which, contrary to the basic geometrical assumption of flexure theory in the Solid Mechanics, the strain changes in the beam height during bending is typically "Non-linear". i Indeed, the RCS, as the Elastic Composite, Reinforced Lightweight Concrete (ECRLC), do not behave as most of the solid materials in bending. i In the "Resilient Composite Systems", distributed pores and/or appropriate lightweight aggregates or beads, accompanied by the reticular structure of the strengthened conjoined matrix, bring about the expedient internal shape changes during bending and continuing the elasticity in bending with the said nonlinearly pattern. This means better distribution of the stresses and strains and better utilizing the potential capacities of the employed reinforcements in bending and tension; whereas, in the usual lightweight concretes for instance, distributed hollow pores (such as the gas bulbs in the cellular concretes) or lightweight aggregates (such as Plastic, Rubber or polystyrene beads or any other kind of lightweight aggregates such as Perlite and Vermiculite) decrease the modulus of resilience in bending and could increase "the possibility of beam fracture of brittle and primary compressive type" in bending (compared to the concrete with higher density) according to the case. i In this way, by using the mentioned method to make the said particular composite systems, we could considerably increase the modulus of resilience and bearing capacity in bending "together with" significant decrease of the weight and also possibility of beam fracture of primary compressive type. Through making these particular integrated functioning systems, for the first time, the said (paradoxical) properties have been concomitantly fulfilled in "one functioning unit" altogether. i Respect to the special pattern of the strain changes during bending in the particular Resilient Composite System called as the ECRLC, this system as an integrated functioning unit with the reticular arrangement and texture has more strain capability (particularly within the elastic limit), energy absorption and load bearing capacities in bending compared to the usual reinforced concrete beams. i Thereby, through employing this applied structure, solving some of the main problems in lightweight concretes application, especially the deadlock of brittle and insecure being of fracture pattern in many of the usual reinforced lightweight concrete structures, is provided; reaching to the high bearing capacities in bending elements (even with low dimensions & weights) is to hand, and getting access to a simple and practical opportunity for "qualitative development of capabilities of using lightweight concretes" (especially with oven-dry densities of < 1350-1400kg/m3 and compressive strengths of <14-17mpa, and even with oven-dry densities of < 800kg/m3) is conceivable . i Naturally, by more studies in the field, these structures and their applications in various fields could be developed more. i *** - (Source (Open Access - Kamyar Esmaeili: "Elastic Composite Reinforced Lightweight Concrete as a Type of Resilient Composite Systems"; The Internet Journal of Innovative Technology and Creative Engineering (IJITCE); 2012; 2(8): 1-22.
