Fundamental Evaluation and Hydration Heat Analysis of Low Heat Concrete with Premixed Cement

(Received February 11, 2014 / Revised March 19, 2014 / Accepted March 24, 2014)This study carried out to evaluate the hydration heat analysis and fundamental characteristics such as air content, slump, compressive strength and dry shrinkage according to concrete with premixed cement, ternary concrete and OPC concrete for using concrete wit hpremixed cement. The results of experiment are founded that concrete with premixed cement have sufficient performances such as workability, compressive strength and dry shrinkage. Also, the results of hydration heat analysis are founded that concrete with premixed cement have more performance than ternary concrete and OPC concrete at a point of view for the quality control such as thermal crack reducing and economic benefit. Therefore, it is desirable that concrete with premixed cement should be used to rise durability performance and convenience of maintenance.키워드 : 혼합 시멘트, 기초물성, 수화열 해석, 현장적용Keywords : Premixed cement, Fundamental characteristics, Hydration heat analysis, Field application* Corresponding author E-mail: jkjeon31@kolon.com
