Use of municipal solid waste incineration bottom ash for roller compacted Concrete
2020Co-Authors: Zhao Zengfeng, Hyoumbi Tchungouelieu William, Michel Frédéric, Courard LucAbstract:audience: researcher241 million tons of municipal solid waste (MSW) is generated annually in the European Union (data from 2014), which produce 16 million tons of MSW incineration bottom ash (MSWIBA) per annum. Due to the promotion of waste recycling, the use of MSWIBA as construction materials has gained much attention during the last decade. In this paper, the use of MSWIBA as aggregate for roller compacted Concrete has been assessed.Ecolise

A study on performance of Roller-Compacted Concrete for pavement
Construction and Building Materials, 2017Co-Authors: Chamroeun Chhorn, Seong Jae Hong, Seung Woo LeeAbstract:Abstract In this study, field test investigation is conducted on Roller-Compacted Concrete pavement (RCCP). A total of five sections of RCCP were constructed in Seokcho of South Korea for this test. Vebe time, a represented parameter of consistency, is employed as quality control parameter for RCC mixture. Performance related properties and surface properties of each section were investigated and correlated to the quality control parameter. Based on the findings from previous researches and results from this field performance investigation, some recommendations for improving mixture design of RCC are suggested.

A Study on Construction Methods of Roller Compacted Concrete Pavement for Bike Roads
Journal of the Korean Society of Road Engineers, 2011Co-Authors: Changho Lee, Young-kyu Kim, Jae-gyu Kang, Cheolwoo Park, Seung Woo LeeAbstract:Usage of bicycle has been supported the universal reduction of energy consumption and . For the same purpose, new constructions for long length bike roads are planned in Korea. Recently, laboratory tests of physical properties and resistance against environmental loading about optimum mix design of roller compacted Concrete, that have advantages of high structural performance by cement hydration and aggregate interlocking, simple construction procedure and low construction cost, are performed for the effective construction of new bike roads. However, properties of roller compacted Concrete had different results between laboratory and field tests since it had different compaction method. Also, construction method of roller compacted Concrete are not defined for the application of bike roads since it had different demand performance such as thin pavement thickness, low strength and etc with road pavements. Thus, in this experimental research was launched to evaluate the core properties, visual inspection, compaction ratio, water content, thickness reduction rate of roller compaction, skid resistance and roughness by experimental construction about variable mix proportion and compaction method based on laboratory test results. And construction method of roller compacted Concrete pavement were suggested for the application of bike roads.

Three dimensional modeling of thermal and structural analysis of roller compacted Concrete dam
2010Co-Authors: A. A. Abdulrazeg, Khaled Hamood Bayagoob, Jamaloddin Noorzaei, Mohd Saleh Jaafar, Thamer Ahmed MohammedAbstract:Cracking due to thermal stress is one of the most important problem arising during the consecution phase in roller compacted Concrete dams. This phenomenon is due to cement hydration, and environmental boundary condition which introduce thermal gradients in the dam body. The present investigation an attempt is made to develop a three-dimensional finite element code for coupled thermal and structural analysis of roller compacted Concrete dams. The crack development within the dam body has been assessed using the proposed crack index. Finite element results have shown that, the higher temperature zone is the centre of the dam body with maximum predicted temperature of 42 0C, which gradually decreased to reach approximately the air temperature at the boundaries. The tensile stress developed in the dam body rang is 1.0 and 5.0 Mps.

Three Dimensional Nonlinear Temperature and Structural Analysis of Roller compacted Concrete Dam
Cmes-computer Modeling in Engineering & Sciences, 2009Co-Authors: Jamaloddin Noorzaei, Khaled Hamood Bayagoob, A. A. Abdulrazeg, Mohd Saleh Jaafar, Thamer Ahmed MohammedAbstract:This paper focuses on the development, verification and application of a three-dimensional finite element code for coupled thermal and structural analysis of roller compacted Concrete dams. The Kinta RCC gravity dam, which is the first roller compacted Concrete dam in Malaysia, has been taken for the purpose of verification of the finite element code. The actual climatic conditions and thermal properties of the materials were considered in the analysis. The structural stress analysis was performed using the elasto-plastic stress analysis. The Mohr yield criterion which is widely used for Concrete plasticity modeling was adopted in this study. The results have shown that, the elasto-plastic analysis can redistribute the state of stresses and produces a more realistic profile of stresses in the dam.
