In the thesis,we had prepared P(AA/AM)/RHA hydrogel composites, and changed the dosage of RHA, compared to P(AA/AM) hydrogel without RHA. FT-IR spectrum was used to identity the functional group of hydrogels. SEM was observed the surface of hydrogels. Then the hydrogels was determined water absorbency in deionized water、saline solution of different concentration and pore solution. P(AA/AM)/RHA hydrogel composites were used as self-curing agent, added to cement paste and mortar. We compared mortar added to RHA composites with that added general P(AA/AM) hydrogel for the influences of weight-loss、relative humidity、drying shrinkage、autogenous shrinkage and setting time. Further, the cracking index in cement paste and the surface of cement paste were determined, observed and discussed cement hydration. The results indicated that the higher water absorbency of all tested P(AA/AM)/RHA hydrogel composites in saline solution, and better water retention in pore solution. When P(AA/AM)/RHA composites was added to mortar and cement paste, it reduced weight-loss、drying shrinkage and autogenous shrinkage, improved compressive strength and internal humidity, lower cracking formation had good influences in cement paste.

碩士 === 國立臺灣師範大學 === 化學系 === 106 === Rice husk ash (RHA) was very common waste in agricultural production. In the thesis,we had prepared P(AA/AM)/RHA hydrogel composites, and changed the dosage of RHA, compared to P(AA/AM) hydrogel without RHA. FT-IR spectrum was used to identity the functional group of hydrogels. SEM was observed the surface of hydrogels.
