Many researches are conducted to reduce latex content because latex is expensive. In these study, the durability of concrete containing extra admixture was compared with latex mixing ratio. From the results, when latex content was increased, bending strength and bonding strength were increased. However, the compressive strength, relative dynamic young’s modulus and the amount of passing charge did not show a noticeable difference with latex ratio. And, the peak of micro-pores was changed from 100nm to 50nm
