Application of sulfur Concrete for lining of Irrigation canals

In spite of that، there are variety of construction materials and methods for lining of irrigation canals، cement concrete is the most common construction material used for canal lining in Iran. However، due to high costs of preparation and application of cement concrete and its sensitivity to technical criteria such as mixing design، executive and curing methods، and impossibility of total observance of such criteria in small projects e. g. canal lining، an feasibility study of the use of alternative materials is inevitable. So، in this research using of precosted sulfur concrete tiles for lining of irrigation canals was investigared. Sulfur concrete is made up of molten sulfur and sulfur modifier additive، fine and coarse aggregates which results in a hard material similar to cement concrete that can be used as a construction material. For this purpose، a small canal with a length of 60 meters was constructed and lined using sulfure concrete tiles. Then the seepage losses and roughness of lining were evaluated. Based on the results of the investigation، the seepage losses and Maning coefficient of lining were determined about 0. 14 m3/m2/day and 0. 013 respectivly. Also lake of improper equeipments for construction and application of sulfur concret was determined as the main excutive problem in lining of small irrigation canal using sulfure concrete tiles.
