EXPERIMENTAL STUDY ASSESSING THE STRENGTH AND CRACK RESISTANT CHARACTERISTICS OF SISAL FIBRE REINFORCED CONCRETE
Abstract
Generally, cement concrete is weak in tensile strength and even the steel reinforced concrete has limited ductility and little resistance to cracking. Researchers are using agricultural and industrial waste to improve the strength properties of concrete and to lead sustainable development. This environmental reason has generated a lot of
concern in the construction world. Natural fibres, as reinforcement, have recently attracted the attention of researchers because of their advantages over other established materials. Addition of fibres can increase strength and also reduce plastic shrinkage and drying shrinkage by arresting the propagation of crack. In this project, a
study is conducted to analyze impact of using sisal fibre to reinforce the cement concrete components. Sisal fibre is one of the prospective reinforcing materials that its use has been more experiential than technical until now. Presently, Sisal represents the first natural fibre in commercial application, in which it is estimated in more than
half of the total of all natural fibres used. They are environmentally friendly, abundantly available, renewable, economical and have low density. From this experimental study to overcome the deficiency of the conventional concrete, it is found that sisal fibres in combination with steel fibres can prevent the concrete from cracking. By testing the samples, we have also noticed an increase in strength of the concrete too.
