Nanoindentation Size Effects for Calcium Silicate Hydrate

摘要：

Hardness of Calcium Silicate Hydrate (CSH) at different ages was measured by nanoindentation test. The results show obvious indentation size effect in hardness of CSH. Hardness decreases with increasing depth. Moreover. both Iow density CSH and high density CSH follow the same size effect law in hardness. This phenomenon further indicates that two types of CSH are of the same basic composition but different packing densities.
