英文摘要
Pore structure in aggregate was measured by Mercury Intrusion Porosimetery (MIP) test and Gas adsorption test. In MIP test, pore structure which diameter is over 10 nm was detected. And in Gas adsorption test, pore structure which diameter is under 10 nm was detected. In this research, it was found that shrinkable aggregate contains a lot of small pore structure which is large surface area. And it was found that there is no difference in large pore structure which was detected by MIP test. This result indicated that it was difficult to identify aggregate is shrinkable or not by water adsorption test.
