3.PREFORMED CORK EXPANSION JOINT FILLER FOR CONCRETE PAVING ANDSTRUCTURAL CONSTRUCTION
7.Abstract: The basic mechanical properties of full mix concrete and its wet-screened concrete incorporating water-reducing agent and air entrained agent tested,such as compressive strength,tensile strength,compressive elastic modulus,tensile elastic modulus,ultimate tensile elongation,flexural characteristics and abrasion resistance,and the relationship of various mechanical properties for the two kinds of concrete is established.The results are important for mass full mix concrete,especially for concrete incorporating air entrained agent.
