Abstract
Effect of three types of setting accelerators such as calcium nitrous, calcium nitrate and C-S-H micro crystal dispersion on early strength enhancement of mortar with blast furnace slag cement were investigated. As a result, it was confirmed that compressive strength of mortar at early age had been enhanced by each accelerator, among them, the accelerator of C-S-H type showed the highest promoting effect. Furthermore, it was found that when the dosage is 4% or more, the initial strength designated by construction procedure can be secured and the productivity of construction work can also be improved.
