The polymer-modified mortar has better tensile strength, impact resistance, wear resistance, durability. Low thermal and electrical conductivity, high corrosion resistance and very good strength to weight ratio makes polymers are very attractive materials for such engineering applications. Polymer and composite materials are up to ten times lighter than typical metals. Polymer binders set very quickly and give resistance to the weathering effect, and thus useful for repairing existing structures. of Advantages and Disadvantages Relative to Traditional DSC Leonard C. Thomas TA Instruments, 109 Lukens Drive, New Castle, DE 19720, USA ABSTRACT This paper outlines the basis for the Modulated DSC technique and shows its value in solving analytical problems that cannot be readily tackled by traditional DSC.
