Novel concrete synergist and preparation process thereof
The invention discloses a novel concrete synergist. The percent of the components of the novel concrete synergist is 60% to 80% of anti-bleeding component, 5% to 15% of enhancement component, 2% to 20% of densification component, 0.5% to 10% of dispersion component, 0.2% to 2% of entraining component and 1% to 8% of compounding component; the anti-bleeding component contains polysaccharides and/or cellulose ether and/or polyacrylamide; the enhancement component contains ethylene glycol isopropanolamine and composition of the ethylene glycol isopropanolamine, triethanolamine and triisopropanolamine; the densification component contains nano silicon dioxide and/or colloid silicon dioxide monomers; the dispersion component contains MF and/or TCL and/or NNO; the entraining component contains sodium dodecyl benzene sulfonate and/or sodium lauryl sulfate; the compounding component is polymeric alcohol amine and/or polymer polyol, respectively. The invention further provides a preparation process of the novel concrete synergist. The novel concrete synergist and the preparation process have the flowing technical effects that 1, the strength of concrete can be enhanced; 2, the usage of cement is reduced under the same strength; 3, the permeability coefficient of chloride ions can be reduced, and the slump loss is reduced.
