To comply with recent international trends and initiatives, and in order to help achieve sustainable development, Korea has established a greenhouse gas (GHG) emission reduction target of 37% (851 million tons) of the business as usual (BAU) rate by 2030. Regarding environmentally-oriented standards such as the IGCC (International Green Construction Code), there are also rising demands for the ...

this paper presents theoretical and numerical state-of-the-art information in the field of hygro-thermo-mechanical deformation simulation in structural concrete. the aspects discussed include coupled hygro-thermo-mechanical performance of porous materials including concrete, multi-scale simulation of concrete properties especially the volumetric and structural deformation performance, and the m...

todays applying concrete structures is more usual than other structures which are used in buildings as in most of the world’s countries the application ratio of concrete to steel has increased from 10 to 1. sometimes these structures require strengthening vulnerable members because of deficiency in their loading system in usual and critical conditions. there are different methods for strengthen...

Earth-moist concrete mixes are the starting substance for the mass production of concrete products like pipes, slabs, pavement stones and curb stones. The working properties of earth-moist concrete (EMC), caused by its dry consistency, are advantageous. So, in comparison to normal-weight concrete, the consistency of EMC allows for direct stripping of concrete products after filling and vibratin...

Tribolium castaneum (Herbst) is a cosmopolitan pest of stored products, grain processing, and foodwarehouses. This studywas initiated tomore fully characterize the role of structure, sanitation, and trap location on capture of T. castaneum in pheromone-baited pitfall traps commonly used in insect monitoring programs. Food patches, spatial structure, and trap position were manipulated in pilot s...

Since the aggregate is 80 % of the total volume of the concrete and mortar, the characteristic properties of the aggregate affect the fresh and hardened properties of the concrete and mortar [1]. The characteristic properties of the aggregate such as the shape, the size and structure affect the properties of the fresh concrete and the mortar like workability, settlement, pumping and segregation...
