 note = {Concrete has a fault that crack is caused by relatively small drying shrinkage because of its low tensile strength. Recently, polymer is mixed into concrete to improve some physical properties such as modulus of rapture, tensile strength, drying shrinkage and permeability. This paper reports the result of an experiment carried out in order to reveal several properties of a polymer cement concrete which is prepared using polypropylene emulsion. 
   The results obtained are as follows;
(1)	The polymer selected here has little effect on compressive strength.
(2)	Tensile strength of concrete increases by about 20%, when the polymer is added.
K3A	The polymer cement concrete shows smaller shrinkage by about 20-30% than the additive-free concrete.
K4)	The addition of the polymer improves bond strength of concrete.
(5)	The absorption of water of concrete decreases as the amount of the polymer added increases.},
