An Investigation on the Materials of Lightweight Concrete

Abstract

Lightweight concrete has drawn much interest from the building sector, due to its exceptional characteristics and possible advantages. This article thoroughly analyses the benefits of employing lightweight concrete as a practical substitute for regular concrete. The assessment includes investigating several factors, such as material properties, structural effectiveness, sustainability, and economic factors. Firstly, the types of lightweight concrete and different kinds of aggregates used for this type of concrete are discussed briefly in this article. The main objectives of the article are the primary characteristics of lightweight concrete, such as its decreased dead load and reduced density while maintaining a certain compressive strength. Reviewing several articles found that the compressive strength of lightweight concrete ranges from 2.0 to 37.0 MPa, whereas with the addition of chemicals, the strength rises to 62.0 MPa. The benefits of lightweight aggregates such as expanded clay, shale, and pumice are highlighted in connection with how they contribute to the attributes of lightweight concrete. The article also assesses the environmental features of it and the possibility of using recycled materials and different types of chemicals, such as polypropylene fiber, bottom ash, etc. The advantages of producing lightweight concrete are examined to evaluate the ecological effect of its use. These advantages include reduced shipping costs and reduced building waste. The disadvantages of its concrete are also described shortly. Not only the history of this concrete but also the scope of further research work about it is discussed.
