Study on the Strength Development of cement paste using High-Early-Strength Cement and Hardening Accelerator

조강시멘트와 경화촉진제가 압축강도에 미치는 영향에 대한 실험적 연구

In order to develop concrete generating compressive strength of 15MPa~30MPa aging for 6~12 hours in the room temperature curing, Hardening accelerator containing Ca²⁺ mixed with rapid hardening portland cement containing C₃S in quantity. The result was that the more addictive contents of Hardening accelerator is, the more greatly early compressive strength was improved. That s because the composition of Ca(OH)₂ was mass-produced at early-ages.
