气化炉渣的碱活性研究

目前混凝土骨料资源短缺问题突显,气化炉渣是潜在资源.若采用气化炉渣作细骨料,首先需要判别气化炉渣的碱活性.试验按照砂浆棒快速法研究气化炉渣的碱活性,用三个主要粒级的气化炉渣替代天然砂制作砂浆棒,测定各龄期砂浆棒的长度.试验结果表明天然砂砂浆棒28 d的膨胀率为0.09%,而含有气化炉渣的各组砂浆棒膨胀率均小于0.06%,且0.63 mm粒级是碱硅酸型碱骨料反应的敏感粒级.作为混凝土细骨料使用时,气化炉渣不属于碱活性骨料,反而对碱骨料反应膨胀有一定抑制作用.应用于混凝土时,不必担忧气化炉渣会引起碱骨料反应危害.     

Effects of Halogen Substitution on Naphthazarin Tautomerism in the Ground and Excited States

5,8-Hihydroxyl-1,4-naphthazarin was taken as a model compound to explore the effect of halogen substitution on intramolecular proton transfer process. Calculations indicate that the substitution in the R2- and R4-positions far away from the active region has much weaker influence on the IPT process than that in the R1-and R3-positions. IPT barriers for substitution in the R1-position are higher than that of parent molecule. However, it is quite reverse for substitution in the R3-position. The IPT process is a proton transfer process coupled with charge separation and coulombic interaction would be dominant during this process. As for naphthazarin, halogen substitution would decrease the quantum yields of O2 but increase those of 1O2.     

Reactivity Ratios of Diethyldiallylammonium Chloride with Acrylamide or Acrylic Acid

The compositions of copolymers of diethyldiallylammonium chloride (DEDAAC) with acrylamide (AM), acrylic acid (AA) or sodium acrylic acid (NaAA) at low conversion were determined by elemental analysis, and the reactivity ratios of monomers in copolymerization were obtained by Kelen-Tudos method. The results showed that the reactivity ratios rDE and rAM are 0.31 and 5.27 for DEDAAC with AM, rDE and rAA are 0.28 and 5.15 for DEDAAC with AA, and rDE and rNaAA are 0.40 and 3.97 for DEDAAC with NaAA, respectively. The copolymerizations for DEDAAC with AM, AA or NaAA are non-ideal copolymerization and the products are random copolymers.
