A step towards sustainable glass fiber reinforced concrete utilizing silica fume and waste coconut shell aggregate
Abstract Today, it’s getting harder to find natural resources for concrete production. Utilization of the waste materials not just helps in getting them used in concrete, cement, and other construction materials, but also has various secondary advantages, for example, saving in energy, decrease in l...
