METHOD FOR IMPROVING DURABILITY OF POROUS CONCRETE |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a method for improving durability of porous concrete and its strengths as well. <P>SOLUTION: Fine powder such as silica fume and an extra-thin and short synthetic fiber having a high strength, a low ductility, and a high elastic modulus are mixed into a porous concrete to improve its strengths and durability. Especially for generating high durability and a high strength, this kind of consideration on materials is required. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
