Synthesis and performance study of new polycarboxylate superplasticizer
Journal of Physics: Conference SeriesAbstract Acrylic acid, oxidant, and reducing agent are essential raw materials for the synthesis of the polycarboxylate superplasticizer. Adjusting their amounts can change the molecular weight and structure of the polycarboxylate superplasticizer.

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.

Influences of chloride immersion on zeta potential and chloride in concentration of cement-based materials [PDF]
, 2015 In this paper, the zeta potential of freshly mixed cement paste and hardened cement pastes, as well as the concentration index, was measured. The influences of chloride concentration in mixing water and slag content on zeta potential of freshly mixed ...

Investigation on the mechanisms govergning the robustness of self-compacting concrete at paste level [PDF]
, 2016 In spite of the many advantages, the use of self-compacting concrete (SCC) is currently widely limited to application in precast factories and situations in which external vibration would cause large difficulties.
