The Strength Properties Activated Granulated Ground Blast Furnace Slag with Aluminum Potassium Sulfate and Sodium Hydroxide

Abstract

In this paper, the effects of sodium hydroxide (NaOH) and aluminum potassium sulfate (AlK(SO 4 ) 2 ․12H 2 O) dosage on strength properties were investigated. For evaluating the property related to the dosage of alkali activator, sodium hydroxide (NaOH) of 4% (N1 series) and 8% (N2 series) was added to 1~5% (K1~K5) dosage of aluminum potassium sulfate (AlK(SO 4 ) 2 ․ 12H 2 O) and 1% (C1) and 2% (C2) dosage of calcium oxide (CaO). W/B ratio was 0.5 and binder/ fine aggregate ratio was 0.

Pore and Efflorescence Characteristics of Alkali Activated Slag-Red Mud Cement Mortar depending on Red Mud Content

“…알 칼리활성화 시멘트는 산업부산물의 재활용과 환경부하 저감 등의 환경적인 장점과 조기강도 증진, 낮은 수화열, 우수한 화학저항성 등의 기술적 장점을 가지고 있어 많은 연구가 이루어지고 있다 [3]. 알칼리활성화 슬래그 시멘트의 자극제 로서 주로 쓰이고 있는 수산화나트륨 수용액(NaOH)과 규산 나트륨 수용액(Na 2 SiO 3 )은 우수한 성능이 검증된 자극제로 서 평가되고 있다.…”

Development of Energy-Based Impact Formula—Part I: Penetration Depth

“…Various fibers have been added to increase the ductility and energy dissipation capacity of the concrete, and blast furnace slag was added to improve the fluidity and strength. Concrete with various properties has been produced by varying the concrete mixture and methods [6]. In particular, new concrete matrices exhibit improved tensile strength due to the presence/addition of steel fibers.…”
