Abstract: Abstract Lignosulfonates are waste products of the pulp and paper industry. The effects of various metal-cation-containing lignosulfonate-based plasticizers on the properties of concrete mixtures produced using cements with various Ca(SO4)ยท2H2O, tricalcium aluminate, and tetracalcium aluminoferrite… read more here.

DOI: 10.1016/j.conbuildmat.2019.117255
Abstract: Abstract The development of formwork pressure is essentially affected by the rheological behavior of fresh concrete, while the shear behavior itself might be influenced by the magnitude of normal pressure. A test set-up was developed… read more here.

DOI: 10.3390/fluids3040106
Abstract: Rheology of a concrete is mainly controlled by the rheological behavior of its cement paste. This is the main practical reason for the extensive research activity observed during 70 years in this research subfield. In… read more here.
