Construction of Sustainable Rigid Pavements by Usage of Vitrified Polish Waste Admixed Fibre Reinforced Concrete
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 8
Abstract
Rigid pavements are considered to be superior to other types of pavements because of their load carrying capabilities and long life, they also require less maintenance and rehabilitation when compared to bituminous pavements. But rigid pavements do not form a major part of India’s transportation system because of their high initial construction cost, with cement being its primary ingredient. But the condition is slowly changing, by knowing the advantages of rigid pavements they are also now constructed vastly along many road transit networks of the country and white toppings are provided on damaged bituminous pavements, Various mineral and chemical admixtures are used in construction of concrete pavements to improvise the engineering properties of concrete and to reduce their initial cost of construction. Currently a wide research is going on in using industrially generated waste materials as a partial replacement of cement in Pavement Quality Concrete (PQC). In previous studies, industrially generated wastes such as fly ash, silica fume, etc., are used successfully as partial cement replacement in PQC. Here in this study, an attempt is made to replace the cement partially with industrial generated waste material, Vitrified Polish Waste (VPW) in varying proportions of 5% and optimum addition is found out. There by improving pavement sustainability and reduction of waste disposal problems for vitrified tiles industry, also considering other major issues in concrete pavements like micro shrinkage, cracking and low flexural strength the usage of polyester fibre Recron -3S is also done to cope up with above problems. The optimum replacement of VPW is again mixed with varying proportions of polyester fibre Recron-3S from 0.1% there by improving the pavement’s flexural strength and other properties at optimum fibre dosage. Then the results are compared with ordinary M40 grade of concrete.
