The present invention relates to a latex modified concrete composition, and more specifically, unlike a method of filling concrete pores by silica fume, slag, etc. using an ion-supplying admixture, the pores of concrete are completely closed, and as latex is additionally used The present invention relates to a modified concrete composition having greatly improved bending resistance, water tightness, chloride penetration resistance, and compressive strength. The modified concrete composition according to the present invention includes 100 parts by weight of cement, 300 to 800 parts by weight of aggregate, 20 to 80 parts by weight of water, and 2 to 6 parts by weight of latex, and 0.2 to 2 parts by weight of ion supply admixture, and organic It comprises a metal salt 0.3 to 1.5 parts by weight. |
