High-workability concrete
The invention discloses a concrete which is composed of the following components in parts by mass: 700-710 parts of fine sand, 1000-1200 parts of macadam, 400-450 parts of cement, 0.4-0.5 part of water reducing agent and 150-160 parts of water. The water reducing agent comprises acrylic acid, an acrylamide water solution, thioglycolic acid, sodium hydroxide, 2,2-azobis(2-aminodipropenyl)hydrochloride and water. The concrete disclosed by the invention is especially suitable for manufacturing cement pipes.
