Abstract
Disclosed herein is a method for adjusting the consistency of a concrete mix by adding a water-absorbing polymeric material or a thickening agent of carboxymethylcellulose to a fresh concrete mix.
Claims2
A method for adjusting the consistency of previously-mixed concrete having a slump value of 8 cm which comprises adding water-absorbing polymeric materials comprising one of a copolymer of acrylic acid with vinyl alcohol, and a polymer of sodium acrylate to the previously-mixed concrete in a ratio of 1-2 kg water-absorbing polymeric material per m.sup.3 of said previously-mixed concrete to adjust the consistency of said previously-mixed concrete to a slump value of lower than 3 cm before hardening.
A method for adjusting the consistency of previously-mixed concrete having a slump value of 8 cm which comprises adding a thickening agent of carboxymethylcellulose to the previously-mixed concrete in a ratio of 0.1-0.2 kg thickening agent per m.sup.3 of said previously-mixed concrete to adjust the consistency of said previously-mixed concrete to a slump value of lower than 3 cm before hardening.
