Analysis of Carbonation Behavior of Cracked Concrete

The crack and carbonation of concrete pose a great challenge to its durability. Therefore, this paper studies the effect of cracks on the carbonation depth of cement paste under different factors. The relationship between carbonation and cracks was determined, and the carbonation mechanism of cement paste with cracks was clarified. The results show that a small water–binder ratio can effectively inhibit the carbonation process. The bidirectional carbonation enlarged the carbonation area around the crack. Within 21 days of the carbonation, the carbonation depth increased with carbonation time, and the Ca(OH)₂ on the surface of the specimen was sufficient, allowing for a convenient chemical reaction with CO₂. The influence of crack width on the carbonation process at the crack was greater than the influence of the crack depth. Carbonation influenced the hydration of cement-based materials, altering the types and quantities of hydration products. In conclusion, accurately predicting the regularity of carbonation in cracked structures is critical for improving the durability of concrete.

Box-Behnken响应面法优化“三六九”复方膏剂的制备工艺

目的 优化“三六九”方剂中挥发油组分的提取工艺,制备“三六九”缓释凝胶膏剂。方法 采用Box-Behnken效应面法,以“三六九”组方挥发油得率为响应指标,原料粒度、萃取温度、萃取时间为考察因素,结合二项式方程拟合试验结果以确定组方挥发油提取的最优提取条件,并采用乳化超声-旋转蒸发法制备基于 β-环糊精纳米脂质载药的凝胶膏剂,以感官评价、赋型性测定、皮肤追随性、耐寒性评价、耐热性评价作为其质量评价标准。结果 “三六九”方剂挥发油的最佳处方工艺为原料粒度过40目筛,萃取时间3 h,萃取温度50 ℃。提取得到挥发油量(0.469±0.021)mL,即挥发油得(1.78±0.08)mL·g^-1。评价结果显示,“三六九”凝胶膏剂具有稳定的赋型性、耐热性与耐寒性,同时具有较好的黏性与皮肤适贴性。结论 Box-Behnken响应面优化法应用简便、预测性好,制备得到的“三六九”凝胶膏剂质量较好。

Development of a lyophilized soybean paste certified reference material for the analysis of ochratoxin A

A certified reference material (CRM) [²KRISS CRM # 108-10-018] for the analysis of ochratoxin A (OTA) in doenjang (fermented soybean paste and popular food in Korea) was produced to ensure the reliability of analytical results in testing laboratories. A home-made doenjang was chosen as a raw material after testing its OTA level. The raw material was freeze-dried, pulverized, sieved and homogenized. An isotope-dilution-liquid chromatography/tandem mass spectrometric method (ID-LC/MS/MS) which was previously developed and validated in this laboratory was used as a higher-order reference method for characterization, homogeneity studies, and short-term stability studies. The CRM had good between-bottle homogeneity with 0.56% relative standard deviation among 10 selected units. The stability of the CRM at −70 °C (the storage condition in our laboratory) and at −20 °C (the possible storage temperature at user sites) were tested for up to 8 months. No change in the OTA content was observed within the measurement uncertainty. The stability of the CRM at room temperature (for regular use and transportation) was also tested and confirmed. The certified value was (49.50 ± 1.17) μg/kg, where the expanded uncertainty was in the confidence level of 95%.
