Low cost materials for highway structures

This paper describes the use of rice husk ash as a pozzolanic replacement for cement and the use of bamboo in reinforced concrete pavements and columns. The ash, produced under controlled conditions and milled to a blaine fineness of 11-12000 cm2/gm can be used to replace up to 20 percent by weight of cement in conventional concrete without any deleterious effects. The bamboo used, a variety known as thyrsostachys oliveri gamble, had tensile and bond strength properties that were adequate for crack control in pavements. However, the compressive strength of the bamboo was only slightly in excess of that of the concrete and the only marginal strength increases were achieved for concentrically loaded columns compared to the strength of loaded columns compared to the strength of the unreinforced concrete columns.
