Abstract In order to study the effects of graphite and carbon fiber on strength conductivity concrete, compressive three types composite concrete with different mixing ratios graphite, glueless rubberized were tested. The results show that 5000 mesh is weakened, but ability reduce resistivity improved, can be stabilized at about 10 Ω·m. performance glue-free in better than fiber. Carbon signifi...

In this study, an FeS2@carbon fiber electrode is developed with FeS2 nanoparticles either embedded in or attached to carbon fibers by using an electrospinning method. By applying this binder-free, metal-current-collector-free FeS2@carbon fiber electrode, both the redox reaction and capacity decay mechanisms for the Li-FeS2 system are revealed by changing the electrolyte (conventional carbonate ...

Today, along with the conventional materials and technologies for reinforcement of building structures, structural systems based on polymer composites are rise. A system consists reinforcing filler (normally, carbon fiber fabric or cloth) adhesive binder. This paper investigated modification epoxy nobake binders to provide a higher thermal resistance mechanical strength. The influence novolac r...

To evaluate whether the increase in serum transcobalamin I, seen in patients with carcinoma, is caused by synthesis of R-binder to tumour cells, the distribution of vitamin B12 R-binder in 125 malignant growths of the digestive tract was studied. Positive staining for R-binder with immunoperoxidase was observed in 85 (70%) carcinomas. Positive staining for R-binder was observed in all four chol...

Zeolite-based catalyst bodies are commonly employed in a range of important industrial processes. Depending on the binder and shaping method chosen, vast differences in the reactivity, selectivity and stability are obtained. Here, three highly complementary micro-spectroscopic techniques were employed to study zeolite ZSM-5-binder interactions in SiO2-, Al2O3-, SiO2 : Al2O3- (2 : 1 mix) and kao...

This study investigates the utilization of slag and fly ash (FA) as alternative cementitious binder. Combination of 60% slag and 40% FA was used as new binder. In addition, for activation of slag and FA, sodium hydroxide and calcium hydroxide was used as a chemical activator by 5% weight of the binder, separately. Water to binder and sand to binder ratios was kept 0.55 and 3 in mortar preparati...

As a new cement-matrix composite material, fiber-reinforced concrete performs excellently in freeze–thaw resistance, tensile and seepage resistance. Since resistivity can be used to evaluate the performance of concrete, basalt–polypropylene (BPFRC) was investigated this study. Various parameters such as fiber type, content, water–binder ratio were also analyzed. The BPFRC tested by an improved ...

Geopolymer is a relatively new substance that has sparked surge of research into nearly every field geopolymers in recent years. It's still on the verge becoming competitive OPC concrete alternative. Mechanical, hardness, and fire resistance properties geopolymer are exceptional. There been no/limited effect fiber integration concrete. In fire-exposed concrete, can help to resist spalling. The ...

forms of radioactivity is apparent when the corticosteroid binder is purified to homogeneity by a series of column Chromatographie fractionation procedures. The binder for 3-methylcholanthrene also has a molecular weight identical to that of the corticosteroid binder as determined by calibration on Sephadex G-75 columns and by sedimentation velocity experiments in the analytical ultracentrifuge...
