Abstract
The relationships between molar parameters of Mg++ ligninsulphonate fractio ns and sorption characteristics, properties of modified cement suspensions, and hardened mortar samples were studied. It has been found that the molar weight of fractions has a significant influence on the sorbed amount of mo lecules of additives, heat evolution, plasticity, volume weight, and compre ssive strength of the samples with the cement used. The sorption characteri stics depend also on the method used for determination. (C) 1999 Elsevier S cience Ltd. All rights reserved.
