Abstract: 
Although the self-compacting concrete (SCC) became the major hot topic in the concrete technology in this millenium, however it is still little of publication regarding the most economic and efficient sustainable SCC mix for the cold & hot weather concreting at temperature -20 0C and 30 0C respectively. The following paper study on the SCC which can provide the sustainable, antifreeze, highly workable, high early & ultimate strength, high durability by incorporating in the fly ash, new antifreeze superplasticiser and low energy cement to cater for the cold & hot weather concreting. The designed SCC for the grade of C30 and C50 can attain high workable mix with high slump flow spread > 50 cm at 1hrs even at dosage as low as 2.5 % and cube strength ratio R-7 >20 %. Their ultimate strength for the designed C30 and C50 SCC at 28 day can attain > 30 Mpa and >50 Mpa respectively by applying the appropriate curing method. Whereas for the designed SCC mixes with the low energy cement can reach the strength ratio R-7 > 20 % and attained the ultimate strength at 28day >30 Mpa and >50 Mpa. The current development of the new antifreeze superplasticiser is a non-chloride, low alkaline, low dosage high performance antifreeze admixture. In this study, the produced sustainable SCC is a perfect choice to be used for the durable, economic and high efficient concreting activities under hot & cold weather.
