Study on High-Temperature Behavior of Coal Gangue-Based Geopolymer Concrete Beams
نویسندگان
چکیده
A newly coal gangue-based geopolymer concrete made from alkaline dry powder activator, gangue, and fly ash has been proposed by the authors. High-temperature behavior of beams with different cross sections reinforced steel bars is investigated in work here. numerical simulation validated existing experiment. analysing section dimensions. Temperature distribution deformation room temperature to fairly high are studied. The isotherm contours at temperatures thermal stress beam time steps obtained analyzed. First, cracking load ultimate cover thicknesses analyzed under conditions. It found that centerline gradually decreases along vertical direction. affected thickness cover. With increase temperature, mid-span deflection increases gradually. High a key factor for behaviors beams.

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
Separation Of Gangue From Coal Based On Histogram Thresholding
Coal gangue is residual abandoned coal, produced after the pre-processing steps of mining. It is an amalgam of several unwanted substances. It is important to separate coal gangue from lump coal before fed to thermal power plants. In this paper, investigation on the fundamental characteristics of coal images and gangue images with digital image processing technology is proposed. The system dete...
متن کاملCoal Gangue Interface Detection based on IMF Energy and SVM
A new method to detect coal gangue interface by utilizing vibration signal of coal and gangue is presented for coal and gangue interface detection on fully mechanized mining face. Because of non-stationary characteristics contained in response signals under complicated environment, empirical mode decomposition algorithm was used to decompose the original vibration signal into the intrinsic mode...
