This paper deals with the study of Nanotechnology experimentation in Civil Engineering which includes the development, advantages and limitations of Nano concreting technologies. For reducing carbon emission during cement manufacturing fly ash is used as a replacement in ordinary Portland cement which is termed as Portland pozzolana cement(PPC), this inclusion relatively increases the workabili...

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.

The following work refers to the issues of increasing strength portland cement with pozzolanic additive due some multifunctional additive. Currently, it is multifactorial additives for ready-mixed concrete that are in demand, which differ from others their multicomponent composition. In this respect, lithoid pumice, a new type aluminosilicate raw material industry, can make worthy competition.
