An Experimental Study on the Workability of High Strength Concrete according to Temperature and Elapsed time

온도조건 및 시간경과에 따른 고강도 콘크리트의 시공성에 관한 실험 연구

The purpose of this study is to present a basic data about the workability of high strength concrete to apply to a field of construction work. The main parameters are as follows; environmental temperature, elapsed time and the use of mineral admixture or not under the same mixing proportions. From the result, Adding amounts of superplasticizer to get a target slump were different in the respective temperature condition. Slump loss according to elapsed time was influenced by environmental temperature. the amount of superplasticizer and the slump loss were decreased by using mineral admixture(garnet powder) and by making concrete under lower temperature.
