Simple and Experienced Use of Elastic Composite, Reinforced Lightweight Concrete (ECRLC) for Lightweight and Integrated Construction to Improve the Earthquake Resistance of Buildings, On the Large Scale

"Lightweight and integrated construction" can be considered a pivotal tactic to improve the earthquake resistance of buildings, on the large scale. "Elastic Composite, Reinforced Lightweight Concrete (ECRLC)", as a cement-based LFNLC ("Lightweight Flexible Nonlinear Composite"), can simply be used to broadly implement this practical policy. Lightness is important in saving energy and reducing the total cost of building construction. The lightweight panels made of ordinary reinforced ultra-lightweight concrete, like insulation concrete, are usually "brittle". The behavior, resilience and toughness of them in bending, shock and impact are not appropriate. By using ECRLC, "the modulus of elasticity and the toughness in bending can be increased" together with "reducing the density" as well as "the removal of the possibility of failing in a brittle, compressive mode". By applying this integrated structure, it is feasible to make flexible (resilient) ultra-lightweight concrete with more flexibility and performance. ECRLC can also be utilized in easily making "ultra-lightweight and insulation, Non-brittle reinforced sandwich panels" (relatively similar to the so-called "3D-panels"), with appropriate behavior in shock and impact. These panels can be cast-in-place or precast upon the case. In general, the items as follows are also considered in selecting any material and construction method speed and ease of transportation and installation and low waste of materials; heat insulation; moisture insulation; being an obstacle to sound; resistance to fire; durability; the rates and amounts of any shrinkage and creep; any capability of self-healing; workability also including formability and the capabilities of cutting, sawing, abrading, repairing, nailing, holding screws, installing installations, and applying the coverings and paints; the amount of covers and coatings, like stucco or plaster, that can be adequate for finishing the surface; usable in-door space; etc. Using ECRLC, as a formable material, in making the "non-brittle ultra-lightweight panels", which are used as non-load-bearing interior and exterior walls, is "a very simple and practical application of ECRLC". Likewise, ECRLC can simply be utilized to make flat and curved roofs & decks and dome-shaped buildings too. (Such simple usages of ECRLC can be done within within the relevant standards and common regulations.)
