The long-term performance of cementitious composites reinforced with coir fibre

Effective prediction of the long-term performance of natural fibre-reinforced cementitious materials is vital for their application. In this study, coir fibres of two different average lengths were combined with cementitious materials and chemical agents to form coir fibre-reinforced cementitious composites (CFRCCs). The composites long-term performance was assessed and compared with two different accelerated ageing processes, i.e. a cement-saturated water ageing, and alternate freeze–thaw ageing. The flexural properties were compared with the properties of the reference mortar. Overall, the flexural strength of 400 days naturally aged CFRCC specimens was weaker than that of the reference mortar. The toughness and ductility of the fibre-reinforced specimens, however, improved. The cement-saturated water ageing method gave a precise prediction of the flexural strength development of 400-day-old specimens, and the freeze–thaw ageing method worked very well for the toughness performance estimation of CFRCCs.

原子力显微镜研究L-半胱氨酸对鲢肌球蛋白溶液热聚集行为的影响

利用原子力显微镜技术分析L-半胱氨酸（L-cysteine,L-Cys）对鲢肌球蛋白热聚集行为的影响。在肌球蛋白溶液中添加5?mmol/L（pH?7.0）的L-Cys溶液,分别进行未加热（25?℃、30?min）、一段式加热（90?℃、30?min）、二段式加热（40?℃、60?min＋90?℃、30?min）处理,分别测定溶解度、表面疏水性、聚集行为表面形貌的变化。结果表明：3?种加热方式低盐条件下L-Cys均显著提高肌球蛋白的溶解度（P＜0.05）;一段式加热时L-Cys显著提高高/低盐条件下肌球蛋白的表面疏水性（P＜0.05）,二段式加热时高盐条件下表面疏水性显著提高（P＜0.05）,其他条件下表面疏水性无明显变化。高/低盐条件下添加L-Cys均能显著改变肌球蛋白聚集行为的表面形貌,使聚集体更加分散,抑制了肌球蛋白的聚集。L-Cys对肌球蛋白溶解度、表面疏水性的影响进一步影响了其聚集行为,改变其聚集形貌。     

Films Prepared with Oxidized Banana Starch: Mechanical and Barrier Properties

Films were prepared using oxidized banana starch and glycerol. Oxidized banana starch was synthesized at three oxidation levels (0.5, 1.0 and 1.5% of active chlorine). Thermal gelatinization and casting were used for film preparation. Tensile strength, elongation, X‐ray diffraction pattern and water vapor permeability were tested. The tensile strength of the films was higher when the oxidation level of the banana starch was higher. When films were stored for 30 and 60 days, there were no statistical differences in tensile strength. However, differences occurred when those films were compared with the films stored for 90 days. The film with added sunflower oil presented the lowest value of elongation at 30 and 60 days of storage. When elongation values were assessed at 90 days of storage no statistical differences (α=0.05) were found among the films prepared from native starch with added sunflower oil, oxidized banana starch with 1.0% and oxidized banana starch with 1.5% oxidation level. All films had a B‐type X‐ray pattern. When the oxidation level in the starch increased, the peaks of crystallinity of the films increased as well. An additive effect was shown due to the higher interactions among polymer chains and among polymer and glycerol molecules as determined by the mechanical properties of the films analyzed. The corrected water vapor permeability (WVP_c) of the films stored for 30 and 60 days did not show statistical differences (α=0.05). The films prepared with oxidized banana starch had the highest WVP_c and those values increased when the oxidation level in the starch was higher. Oxidized banana starch can be used for preparation of films with adequate physicochemical characteristics.
