Abstract
C-S-H is a dominant hydration product of hardened cement materials. Thus, changes of composition of C-S-H have a huge effect on the physical-chemical properties of that. These properties are diffusivity of ion in concrete and shrinkage, and all that. Therefore, it is important to figure out the specific surface area of C-S-H accurately.<br/>The purpose of this study is to figure out the specific surface area which is physical properties of C-S-H. Specific surface area of C-S-H generated from alite was checked up already in our laboratory. So we measured the specific surface area of C-S-H generated from belite, and compared with the specific surface area of C-S-H generated from alite. As the result, it was found that composition of each C-S-H generated from alite and belite were about the same. Furthermore, both specific surface area were in the same range.<br/>Next, we measured amount of gel water at relative humidity 11% to examine the experimental results. The volume of gel pore can be calculated from the amount of gel water. As the results, the amount of gel water of C-S-H generated from alite and that of C-S-H generated from belite were the same. Therefore, validity of experiment results of the specific surface area was recognized. Finally, the specific surface area of C-S-H is not affected by clinker minerals.
