A Relook on Dosage of Basalt Chopped Fibres and Its Influence on Characteristics of Concrete
In recent years, the need for sustainable yet economically viable structural materials has drawn special attention of the construction industry apart from the traditional parameters concerning safety and serviceability. One such material of interest gaining popularity in the twentieth century is the basalt fibre, due to its cost-effectiveness and desirable engineering properties, especially with respect to fire resistance. Basalt fibres are formed from basalt rocks and hence fulfil the concept of sustainable design and green building. Basalt can commonly be used as a structural reinforcing material in the form of bars, sheets, chopped fibres, etc. Talking specifically about chopped basalt fibres, the dosage of fibre plays an important role in its case. This paper mainly highlights the existing studies on the optimum dosage of chopped basalt fibres with respect to strength aspect and points out several critical comments on the relation of fibre content with workability through experimental testing.
