Strength Properties of Mortar According to Types of Binders for Reducing Curing Process of Concrete Secondary Products for Reduction CO2

Abstract Carbon dioxide generated from construction materials and construction material industry among the fields of construction isapproximately 67 million tons. It is about 30% of the carbon dioxide generated in the fields of construction. In order to reducecarbon dioxide in the fields of construction, it is necessary to control the use of fossil fuel consumed and decrease carbon emis-sion by reducing the secondary and tertiary curing generating carbon dioxide in construction material industry. Therefore, thisstudy manufactured mortar by having cement as the Plain and substituting three binding materials up to 50% and then adopteddifferent curing methods to analyze congelation and strength characteristics. Test results for strength property by changing bind-ing materials showed that specimens with blast furnace slag, CSA 15% and CAMC 5% resulted in positive effect for strengthimprovement. Especially, specimens with 50% of blast furnace slag, CSA 15% and CAMC 5% showed the most apparent · Received : May 29, 2014 · Revised : July 4, 2014 · Accepted : August 4, 2014Corresponding Author : Ha-Seog Kim (E-mail : bravo3po@kict.re.kr)Advanced Building Research Division Building Research Department, Korea Institute Construction Technology, 283, Goyangdae-Ro, Ilsanseo-Gu, Goyang-Si, Gyeonggi-Do, 411-712 KoreaTel : +82-31-9100-231 / Fax : +82-31-9100-713 ⓒThe Korean Institute of Resources Recycling.
