Abstract
Porous ceramic having a homogenous pore structure in which pores having radii in a narrow range of 300 to 4000 nm occupy 90% or more of the total pore capacity. The porous ceramic is manufactured by a method including a first step of drying an initial composition containing waste as a main component, an aggregate and a binder. A second step mixes the components of the initial composition dried in the first step. A third step adds water to the mixture obtained in the second step. A fourth step performs extrusion molding with the water-added mixture obtained in the third step. A fifth step fires an intermediate molding product obtained in the fourth step.
Claims6
A porous ceramic comprising:
- a plurality of pores, wherein the pores have a pore radius distribution in which pores with radii of 300 to 4000 nm when measured by performing mercury intrusion porosimetry occupy 90% or more of the total pore capacity.
A method for manufacturing a porous ceramic comprising:
- drying an initial composition of waste, an aggregate, and a binder;
- mixing the initial composition after said drying without adding water;
- adding water to the mixture obtained in said mixing;
- extrusion molding the water-added mixture obtained in said adding to obtain an intermediate molding product;
- and
- firing the intermediate molding product obtained in the extrusion molding.
