Abstract:Three new polycarboxylate-based liquid superplasticizers (SPI-3) and powder superplasticizers (PSPI-3), which are made from SPI-3, are synthesized and evaluated. SP3, which has two different lengths of polyoxyethylene chains in one polymer molecule, showed high cement dispersing capability, good fluidity retention and short setting time. PSP3, which is made from SP3, showed low moisture absorption and excellent antiblocking property. The results show the following properties of PSP3, compared to those of general powder type superplasticizers such as Naphthalene-based powder superplasticizer (NS) and Melamine-based powder superplasticizer (MS). 1) Necessary dosage to obtain equal fluidity is about a tenth. 2) Fluidity retention is better. 3) Setting time is shorter. 4) Compressive strength of mortar is higher. 5) PSP3 is non-formalin type superplasticizer.
