Preparation and properties of retarded cellulose-based polycarboxylic superplasticizers

Journal of Polymer Research
Abstract Cellulose is an important biomass, and the synthesis of chemical products using cellulose is the current hotspot for sustainable economic development. A cellulose-based polycarboxylic acid superplasticizer (CBPCS) was prepared from cellulose hydrolysate, and its properties and mechanism of action were investigated.

Synthesis and rheological properties of retarding polycarboxylate superplasticizers

IOP Conference Series: Earth and Environmental Science, 2019
Abstract In this paper, different types of retarding polycarboxylate superplasticizers (PT-1, PT-2 and PT-3) were synthesized. The structure information and functional groups of the water reducing agent were characterized by gel chromatography and infrared spectroscopy.
