Abstract
Cellulosic sugar acids from lignocellulose biomass are composed of gluconic acid, xylonic acid, arabonic acid, galactonic acid and mannonic acid. The major application of cellulosic sugar acids is cement retarder additive. This study experimentally investigated the performance of cellulosic sugar acids on cement hydration and compared with the commercial sugar acid from crop starch feedstock. The excellent retarding efficiency of cellulosic sugar acids was demonstrated while cement strength and soundness maintained similar to that of starch based sugar acid product. X-ray diffractograms, thermograms, and microstructure analyses showed that the hydration of cement reactions and the formation of cement products were significantly delayed by the addition of cellulosic sugar acids. This study indicates that cellulosic product from low-cost agriculture residue is a promising alternative of commercial product from crop starch feedstock as cement additive.
