 Abstract
In this paper, three kinds of poly(acrylate-co-methylacrylate) with different number average molecular weight(Mn) were synthesized and studied for the effects on the mechanical properties and the fluidities of the cement mortar admixtured with them. The physical properties of the cement mortar are more favorably enhanced by the poly(acrylate-co-methylacrylate) of Mn,, 5,000 than that of Mn, 2,000∼3,000. And the optimum dosage was decided to ca. 0.6 % of cement weight in cement mortar. However, the dispersion abilities of the polymers in cement mortar was not kept long time. This last result could not be explained by the theory that the fluidity of the cement mortar added with the slow releasing polycarboxylates is kept by the releasing of the carboxylic group of the copolymer in alkaline solution of cement paste.
