STUDY ON HIGH STRENGTH AND HIGH FLUIDITY CONCRETE WITH LITHIUM SLAG AND SILICA FUM

It was studied that the effect of addition of lithium slag and silica fume on th e strength and fluidity of concrete; according to the data obtained from the tes t, the rule of 28 day compressive strength of concrete inner added with lithium slag and silica fume was summarized, and the increasing rule of later stage stre ngth of concrete was also studied. A high strength and high fluidity concrete (1 00MPa) can be prepared using grade 42\^5 ordinary Portland cement, medium sand, 5～25mm broken stone, addition of 10%～15% lithium slag and 5% silica fume, wate r cementitious materials ratio 0\^255～0\^268, or inner added 0～15% lithium slag an d 10% silica fume, water cementitious materials 0\^260～0\^305, and proper quant ity of NF-2-6 retarding high effect water-reducing agent.
