The present invention relates to a self-filling geopolymer concrete composition that can exhibit the same or better performance than the cement through the alkali active reaction without using cement, and can improve the quenching phenomenon and low workability of the geopolymer binder. , The self-filling geopolymer concrete composition of the present invention is 0.4 to 0.6 parts by weight of blast furnace slag fine powder, 0.2 to 0.4 parts by weight of fly ash fine powder, and silica based on 1.0 part by weight of the blast furnace slag fine powder, fly ash fine powder and silica fume fine powder. Fume fine powder 0.1-0.2 parts by weight, powder type alkali activator 0.1-0.2 parts by weight, sodium carbonate 0.05-0.1 parts by weight, aggregate 3.0-4.5 parts by weight, antifoaming agent 0.003-0.007 parts by weight, fluidizing agent 0.01-0.025 parts by weight, shrinkage reduction 0.001 to 0.003 parts by weight. |
