Furnace slag is an inevitable by-product of the steelmaking process, and the reuse of furnace slag resources is also an international trend. We used blast furnace slag powder as the alkali excitation material in this study. The alkali-activated binder is mixed with coarse and fine aggregates to form alkali-activated concrete. To meet the high-flow performance of alkali-activated pozzolanic concrete (AAPC), added the plasticizer in a proportion of 1.25%. The concrete was well mixed using a fixed base modulus ratio (Ms), three different liquid-solid ratios (LS) of 0.45, 0.50, and 0.55, and three different normalities (N) of sodium silicate solution of 5%, 6%, and 7% and remained them in the atmosphere. At 7, 28, and 56 days of age, carrying out the engineering properties tests such as hardness, durability, and mechanical properties, and using microscopic to verify the test data. The results show that the slump of AAPC is 550mm to 650mm, which has a longer setting time than the general proportion of concrete, but it has better workability. The high liquid-solid (LS) ratio influences engineering properties significantly, confirming that the proper LS ratio and the normality can improve the hardening properties and durability of high-fluidity AAPC. When the LS ratio=0.45 and the N is 7%, the interface of the furnace slag can destroy through more sodium silicate solution, and the polymerization behavior can stimulate. At 28 days, the compressive strength can reach 29.8Mpa, and the initial ultrasonic wave speed reach more than 3000m/s, which can meet the needs of engineering use.
