Hi am Arulanandan i would like to get details on sulphur impregnated concrete ppt .I came to know that sulphur impregnated concrete ppt will be available here and now i am living at Coimbatore and i last studied in the college (CIT,Coimbatore). and now am doing ME at Anna University regional campus Coimbatore,.So i need it for my project works ......etc

CONCRETE IMPREGNATED IN SULFUR
Sulfur is a low cost cast material that solidifies on cooling and meets the 9 criteria required of a material that could impregnate the concrete. High strength concrete has been produced by impregnation of low strength concrete (aggregate ratio: cement of 8-8.5) with sulfur. Lean concrete requires only 3/4 or less of the amount of Portland cement used in high strength concrete. Sulfur impregnation of lean concrete increases its compressive strength from less than 1/3 to 1-1 / 2 times that of high strength concrete. The maximum absorption of sulfur is achieved by impregnation in sulfur melt under vacuum. Recent work indicates that satisfactory impregnation levels can also be achieved without the use of vacuum. The 8-fold increase in the compressive strength achieved in vacuum is reduced to 5 times without vacuum. Studies also show that while the impregnation of high strength concrete increases its final strength to a value higher than that of low strength concrete, the relative increase in strength and the amount of sulfur absorbed are lower. Sulfur-impregnated concrete (SIC) may be used when resistance, water penetration, chemicals, etc. are required. The available impregnation technology is applicable to prefabricated concrete structures, while the appropriate technology for the impregnation of cast concrete in place needs to be developed.
