| Abstract: | The effect of water-reducing agent dosage and water quantity used on the strength and fluidity of high strength and high fluidity concrete inner added 20% Lithium slag was studied. the compacting technology on the concrete strength was studied. According to the test results, the strength empirical equation of high strength and high fluidity concrete inner added 20% Lithium slag was summarized. C80 high strength and high fluidity concrete may be prepared with Jidong 525 grade Ⅱ portland cement, inner added 20% Lithium slag, 5～20mm broken stone, proper quantity of NF－2－6 retarding super water-reducing agent, water cement ratio not larger than 0.31. |
