Silane type surface penetrants were applied to young age mortar for the purpose of shortening the construction period when silane type surface penetrants were applied to the newly constructed concrete structure and its strength characteristics were investigated. As a result, when the silane type surface penetrants were applied to mortar with age of 7 days, slight increase in strength was observed compared with applying to 28 days of age or compared with the untethered mortar. In addition, in order to estimate this cause, mass change and pore diameter distribution were also measured. As a result, it was considered that the reason why the mortar strength increases at the age of young age was due to the curing effect with the internal water by applying silane type surface penetrants at young age. Therefore, it was considered that there were few problems of strength by applying silane type surface penetrants to the mortar at the age of young age.
