The porosity and distribution of micro-pores inside concrete have important influence on the character of concrete materials,the micro-pores inside concrete distribute mainly in cement-stones of hardened cement grout .

Due to the reducing the bleeding rate and shrinking rate of cement grout and increasing the compactness of the duct grouting,the safety and durability of prestressed concrete structure are improved.
