The Relationship between Gel Content and Drying Shrinkage

Article Preview

Abstract:

In this paper, the relationship between gel content and drying shrinkage has been investigated. The drying shrinkage for different specimens was tested by comparator. Modified Water Absorption Method was used in the semi-quantitative analysis of gel content. Found that (1) The sample, which is high in activity, produces more gel, so does the drying shrinkage. (2) The drying shrinkage is linear correlation with gel content. (3) Sample with higher gel content has thinner pore structure.
