Description
Summary:This article disclosed to design a series of polycarboxylate superplasiticizer (PHC) by free radical polymerization. The PEO grafting side chain desity and main chain compositon of PCE greatly influenced the concrete performance. The PEO long side chain of PCE can produces steric hindrance effect in concrete to provide the flowability. The functional monomer DAC and AMPS incorporated into the main chain can improve the compressive strength. The suitable water dosage in the PHC mix proportion is 145 kg/m3 and 150 kg/m3.
