Abstract The hypothetical human exploration and inhabitation on Mars would certainly be difficult as the planet itself is vulnerable to outer space radiation. radiation consists of solar particle events (SPEs) that could easily penetrate very thin atmospheric layers Mars. Since sulfur concrete identified feasible in situ building material Mars, its shielding capability yet clarified. Here we re...

Multiscale modeling for cement-based materials, such as concrete, is a relatively young subject, but there are already a number of different approaches to study different aspects of these classical materials. In this paper, the parameter-passing multiscale modeling scheme is established and applied to address the multiscale modeling problem for the integrated system of cement paste, mortar, and...

In recent years, the Lamb wave analysis by the multi-channel analysis of surface waves (MASW) for concrete structures has been an effective nondestructive evaluation, such as the condition assessment and dimension identification by the elastic wave velocities and their reflections from boundaries. This study proposes an effective Lamb wave analysis by the practical application of MASW to concre...

We analyze the concrete security provided by a signature scheme described in a recent Internet Draft by McGrew and Curcio.

In this study, novel cross-shaped concrete-filled steel tube (CFST) and (ST) columns were developed. CFST have a high load-carrying capacity excellent performance under seismic conditions, the construction process is fast. order to investigate axial load bearings failure mechanisms, six specimens of ST tested load. Three different forms employed in study; one was an ordinary (OC-CFST), while ot...

This paper presents an experimental study on circular stirrup-confined concrete specimens under uniaxial and monotonic load. The effects of stirrup volume ratio, stirrup yield strength and concrete strength on damage evolution of stirrup-confined concrete were investigated. The experimental results showed that the strength and ductility of concrete are improved by appropriate arrangement of the...

Concrete is the primary building material worldwide with a substantial impact on built environment sustainability. Hence, it necessary to assess concrete’s combined functionality, economic and environmental impact. In this paper, two concrete sustainability assessment frameworks, MARS-SC CONCRETop, were studied. Building identified gaps, new framework, ECO2 was developed. multi-criteria decisio...

This work presents the attempt to develop a production technology for grape–plum low-alcohol beverages and enhance their chemical composition flavor complexity through non-Saccharomyces species. Saccharomyces cerevisiae (SC) pure cultures were used as reference beverages. Pure of Lachancea thermotolerans (LT) co-inoculated with (MIX) included must fermentation at pilot scale. The process involv...
