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: 10.3390/ma15082760
Abstract: In this work, 3-3 type porous lead zirconate titanate (PZT) ceramics were fabricated by incorporating particle-stabilized foams using the gel-casting method. Then, Portland cement pastes with different water/cement ratios (w/c) were cast into the porous… read more here.
