Invention of new methods in strengthening concrete is under work for decades. Developing countries use the extensive reinforced construction works materials such as fly ash and bottom ash and other ingredients in RCC construction. In the construction industry, major attention has been devoted to the use of fly ash and bottom ash as cement and fine aggregate replacements.
But the recently Lightweight Expanded Clay Aggregate (LECA) has been introduced instead of coarse aggregate to make concrete have light weight.
Lightweight concrete is awkward to make a case belong to a unique category material. However, LWC (light weight concrete) has clear edges, and the plunge in the total expense created by the lower dead loads is constantly overshot by the raised production outlay. As a matter of fact, lightweight concrete has surfaced as the agreeable favorite as against the standard concrete in the perspective of a multitude of unrivaled attributes.
The dip in dead weight generally brings about cutbacks in production outlay. The self-compacting normal weight aggregate concrete (SCNC) is to be the favorite for the purpose of development. The surge in the construction expense of SCLC fares positively with that for SCNC. Lightweight aggregate concrete deadweight is assessed to be around 15%~30% lighter than standard concrete, which sufficiently fulfills the mechanical attributes that roadway support requires on the specified density degree.
Rising utilization of lightweight concrete (LWC) brought the requirement for the artificial lightweight total production, which may be accomplished by cold bonding assembling methodology. Production of artificial fly lightweight aggregates with cold bonding process needs much less energy consumption when contrasted with sintering. Lightweight concrete made with natural or artificial lightweight aggregates is accessible in numerous parts of the world. It can be utilized as a part of creating concrete in an extensive variety of unit weights and suitable qualities for different applications. Lightweight aggregates concrete livens up its potency to thwart nearby harm activated by ballistic loading. Lower modulus of flexibility and higher tensile strain limit outfits lightweight concrete opposite standard weight concrete with superior impact resistance. Light concrete material is more and more prescribed by the builders to reach a supportable improvement due to its great strength and thermal properties. The adhesive strength is accomplished from solidity in the binder and interlocking traits of the aggregates, which are constantly focused around angularity, levelness, and extension.
Lightweight Expanded Clay Aggregate (LECA), generally, includes tiny, lightweight, bloated particles of burnt clay. The hundreds and thousands of tiny, air-filled depressions successfully empower Lightweight Expanded Clay Aggregate (LECA) with its sterling strength and thermal insulation qualities and provides comprehensive strength.
