Abstract: Artical analyses factors which affect concrete strength and introduce ways in producing highstrength concrete. It also compares the action of sillica fume in concrete with that of water-reducer, and concludes that potencially sillica fume has stronger influence in producing high-strength concrete than water-reducer does.

Key words: high-strength concrete, water-reducer, sillica fume
