چکیده

Beton ringan geopolimer merupakan salah satu beton yang ramah lingkungan karena proses pembuatannya memanfaatkan prekursor berasal dari alam dan/atau limbah seperti kaolin, abu terbang, dan pozzolan lainnya. ini juga termasuk jenis inovasi memadukan kelebihan geopolimer. Penelitian menggunakan material terdiri prekursor, larutan alkali aktivator, agregat halus, superplasticizer, foam dengan target berat ≤ 1500 kg/m3. Prekursor kaolin terbang persentase 0%, 5%, 10%, 15%, 20% terbang. Perbandingan Na2SiO3 NaOH 2,5:1 konsentrasi 12 M 14 M. aktivator sebesar 0,5. halus 2. Untuk memproduksi digunakan perbandingan foaming agent air 1:40 presentase 50% volume campuran. Perawatan benda uji dilakukan selama 24 jam pada suhu oven 60°C. Hasil pengujian kuat tekan menunjukkan bahwa campuran BRG-0%-14M menghasilkan paling optimum 19,20 MPa 1481,12 SEM XRD peningkatan 0% pori-pori sangat kecil matriks lebih padat (C-S-H) dihasilkannya struktur amorf, akan tetapi adanya semakin besar kurang (C-H) amorf. Berdasarkan penelitian dapat disimpulkan mikrostruktur jauh baik.

Nano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy

ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...

X-ray Microanalysis of Cultured Cells in the Scanning Electron Microscope and in the Scanning Transmission Electron Microscope: a Comparison

X-ray microanalysis of cultured cells as “whole mounts” (i.e., not sectioned) is used frequently e.g., to study mechanisms of ion transport. Cells can be cultured either on solid substrates or on thin plastic films on grids. Cells cultured on solid substrates are analyzed in the scanning electron microscope at relatively low accelerating voltage, cells cultured on thin films can be analyzed in ...

Smart Flexible Microrobots for Scanning Electron Microscope (SEM) Applications

In the scanning electron microscope (SEM), specially designed microrobots can act as a flexible assembly facility for hybrid microsystems, as probing devices for in-situ tests on IC structures or just as a helpful teleoperated tool for the SEM operator when examining samples. Several flexible microrobots of this kind have been developed and tested. Driven by piezoactuators, these few cubic cent...
