<p><P>PROBLEM TO BE SOLVED: To provide a method of controlling pores in porous concrete because the arrangement of the pores in the porous concrete seriously affects the physical property, so that the control of the pores is necessary. <P>SOLUTION: In the method, a three dimensional particle element method program, which is prepared by classifying aggregate by particle diameter, modeling aggregate around which a binder is uniformly stuck, expanding to consider the deformation of the surrounding binder under simulation and further expanding to consider the tamping by compaction and vibration and by which the continuous void in the porous concrete is calculated, is uploaded in a computer. By the method, the arrangement of the aggregate/pores in the porous concrete, the solid volume percentage, the open/closed pore distribution and the open/closed pore volume are controlled by simulating with each physical property value and blending variables of each of the binder, the aggregate and a mold form and the non-deformation quantity of the binder as parameters. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
