Key Points

This research aims to evaluate how different shapes of synthetic calcium carbonate affect the flowability of cement paste.
Evaluated viscosity of cement paste with varying synthetic calcium carbonate shapes.
Compared with traditional cement paste and limestone powder substitutes.
Analyzed particle shape coefficient and surface texture.
Cement paste with calcium carbonate showed higher viscosity than that with only cement or limestone.
Viscosity changes could not solely be explained by particle size distribution or crystal polymorphism.
A significant correlation was found between high shape coefficients (10+) and flowability.

Implication

Evaluation of particle shape's influence on flowability and viscosity in cement paste, indicating significant correlations.
