<p><P>PROBLEM TO BE SOLVED: To provide a high-strength paste composition capable of promptly exerting high compressive strength only by cold curing. <P>SOLUTION: The high-strength paste composition comprises cement, a silica fume, water, a water reducing agent, a defoaming agent, an inorganic fine powder and a high-tension fiber. The cement comprises 40.0-75.0 mass% C<SB POS="POST">3</SB>S and <2.7 mass% C<SB POS="POST">3</SB>A and leaves <25.0 mass% residue on a 45μm sieve. The inorganic fine powder comprises at least one fine powder chosen from the group consisting of a lime stone powder, a silica stone powder, a crushed-stone powder and a slag powder. A mixture of the inorganic fine powder comprises 40-80 mass% particles having a particle size of≤0.15 mm and 30-80 mass% particles having a particle size of≤0.075 mm. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
