Water based inorganic alkali silicate binder of zinc rich primer was modified by adding acrylic resin derivatives. Several series of primer coatings were formulated by adding 5, 10 and 15 wt of acrylic and acrylic/styrene copolymer to potassium silicate binder and used as binder in zinc rich coatings. The formulated primers were applied on low carbon steel plates and the corrosion protection pr...

Gel filtration studies on erythrocyte hemolysate demonstrated the presence of a folate binding protein, apparently of the low-affinity type, that co-elutes with hemoglobin. Further, the folate binder eluted with a low salt concentration after DEAE-Sepharose CL-6B anion-exchange chromatography of erythrocyte hemolysate at pH 6.3. The chromatographic behavior of hemoglobin labeled with [3H]folate...

UNLABELLED Splanchnic venous pooling is a major hemodynamic determinant of orthostatic hypotension, but is not specifically targeted by pressor agents, the mainstay of treatment. We developed an automated inflatable abdominal binder that provides sustained servo-controlled venous compression (40 mm Hg) and can be activated only on standing. We tested the efficacy of this device against placebo ...

This study aimed to investigate the strength and permeability properties of binary ternary systems for producing concrete mixes with a cure time 7, 28, 90, 180 days under high ambient temperatures (about 35–45 °C). The key variables were silica fume (SF) fly ash (FA) water-to-binder ratio (0.18 0.55) needed cementitious normal ultra-high-performance (UHPC). tests conducted BS 1881 ASTM C 1202. ...

abstract: The microstructure of cement pastes is important to understand the effect some parameters in hydration process. In this context, study had as objective evaluate different water/binder (w/b) ratios process cementitious produced with and without incorporation silica fume metakaolin. were obtained 0.3, 0.4 e 0.5, replacement, by weight, Portland for metakaolin, contents 10% 20%, respecti...

This is an experimental study on the development of a low-carbon, eco-friendly cement containing calcium sulfoaluminate expansive agent (CSAe), slag, and silica fume (SF). The to be developed has low water/binder ratio (w/b) 0.5 designed used for structural purposes, with focus its mechanical performance. CSAe, SF were mixed at various mixing ratios. main hydration product slag-based CSAe in ex...
