Acrylamide (AA) is a water soluble white crystalline solid commonly used in industries. It was listed as an industrial chemical with potential carcinogenic properties. However to date, AA was used to produce polyacrylamide polymer, which was widely used as a coagulant in water treatment; additives during papermaking; grouting material for dams, tunnels, and other underground building constructi...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
To improve the construction efficiency of the Longtan Hydropower Project, this paper studies the multi-mode resourceconstrained project scheduling problem in its Drilling Grouting Construction Project. A multiple objective decision making model with bi-random coefficients is first proposed for this practical problem to cope with hybrid uncertain environment where twofold randomness exists. Subs...
A new fully integrated ultrasound based in-line fluid characterization system, FlowViz, has been developed especially for opaque, non-Newtonian industrial fluids. The new embedded and commercially available system is designed to meet industrial requirements. Flow-Viz enables true non-invasive, real-time Doppler measurements and is able to visualize the flow and to rheologically characterize ind...
To reveal the strengthening mechanism and re-failure of grouting on fractured rock, variable-angle shear tests, real-time acoustic emission (AE) tests VIC-3D (non-contact full field strain measurement system) were carried out intact red sandstone (IRS) grouting-reinforced body (GRBFRS). The results show that peak strength IRS GRBFRS decreases with increase angle. Grouting reinforcement mainly i...
Dalam pembangunan bendungan urugan kekuatan pondasi sangat penting. Pondasi harus dipastikan memiliki daya dukung yang kuat, maka dilakukan perbaikan dengan cara grouting. Terdapat dua metode saat pekerjaan grouting yaitu downstage dan upstage. Tujuan penelitian ini untuk mengetahui mana memberikan keuntungan lebih banyak. Metode upstage biaya sebesar Rp2.704.279.000 waktu selama 2350 menit, se...
