Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...

Nanotechnology will serve as a suitable solution to achieve high performance in future construction and construction. Using this new technology, creativity and innovation can be achieved in the building industry. one of these new technologies of smart concrete is that in recent years, many researches and experiments have been done in scientific research centers around the world, so that the con...

this paper is based on an experimental research that examined the effects of concrete`s major parameters on durability of concrete pavements and curbs under freezing and thawing cycles. these parameters include concrete mix design parameters such as water-cement ratio, fine aggregate percentage and using air entraining admixture and simulating real freeze-thaw cycles that infrastructures underg...

Service selection and binding for building composite services is a critical but difficult to resolve issue in the domain of service-oriented computing. This paper proposes an innovative approach to address this issue, in which every abstract component service in the composition is assigned a weight value to represent its importance according to designer scoring and basis path analysis, thereby ...

    Freezing and thawing resulting from the ingression of water into concrete causes cracking or spalling. Corrosive ions such as chloride or sulfate penetrate the concrete surface and eventually reach the reinforcing steel. This causes the steel to corrode.     Because of the high maintenance and replacement costs, responsible officials should be increasingly concerned about the growing number...

As the technology evolves, the existence of different computational devices has made adhoc software development no longer acceptable in the development of multi-platform software applications. This article describes RenderXML, a software tool developed to facilitate the creation of multi-platform applications. RenderXML acts as a renderer, mapping concrete user interfaces (UI) described in UsiX...

We examine the nature of Collaborative Networked Organizations in Government (CNO-G) and identify three core capabilities characterising such organizations Partnership, Coordination and Integration. By considering these capabilities as idioms for the CNO-G domain, we define a conceptual model that expresses such capabilities using modeling abstractions provided by ARCON (A Reference Model for C...

This paper presents detailed numerical simulations predicting the effective thermal conductivity of spherical monodisperse and polydisperse core–shell particles ordered or randomly distributed in a continuous matrix. First, the effective thermal conductivity of this three-component composite material was found to be independent of the capsule spatial distribution and size distribution. In fact,...

The past several years have seen much progress in the area of propositional reasoning and sat-issability testing. There is a growing consensus by researchers on the key technical challenges that need to be addressed in order to maintain this momentum. This paper outlines concrete technical challenges in the core areas of systematic search, stochastic search, problem encod-ings, and criteria for...
