The ureolytic bacteria and nutrients were immobilized in the artificial functional carrier (AFC) self-healing cement mortar, based on AFC-encapsulated bacteria, was prepared for this paper. crack effect of mortars with without under different exposure environments (standard curing, dry–wet cycle water curing) investigated by visual observation surface internal cracks, permeability tests, mechan...

The learning algorithms for working with textual information, proposed by the authors of article, allow not only to speed up process understanding and consolidating course content but also provide a self-reflection component students' activity, which makes it possible control, correct modify algorithm under influence changing communication conditions.

The mechanism of corrosion of reinforcing steel in concrete is discussed based on electrochemical and electron microscopy observations. The importance of calcium hydroxide precipitation on the steel surf ace in the steel/mortar interface is evaluated by placing filter paper around reinforcing steel bar specimens prior to casting in mortar, thus preventing direct contact between steel and mortar...

Discontinuous Galerkin (DG) methods employ discontinuous piecewise polynomials to approximate the solutions of differential equations with boundary conditions and interelement continuity weakly imposed through bilinear forms. Examples of these schemes include the Bassy-Rebay method, the Local Discontinuous Galerkin (LDG) methods, the Oden-Babuška-Baumann (OBB-DG) method and interior penalty Gal...

This paper aims to analyze the characteristics of self-compacting mortar (SCM) with partial replacement cement by water treatment sludge (WTS). contribute minimize environmental degradation arising from production materials used in construction and give a sustainable destination generated plants. In this study, substitution 10 20% for WTS Itajubá Water Treatment Plant Minas Gerais was analyzed....

Polymer modification of mortar and concrete can lead to improved transport and mechanical properties and thus its potential for an inhibiting effect on ASR or on resulting damage was investigated. An accelerated mortar bar test in a NaOH solution bath at 80 oC had already been established as inadequate to assess the behaviour of polymer-cement mortars (PCMs) under ASR, but compared to that of a...

This paper presents part of a research into the small scale modelling of masonry. Small scale testing of masonry has been carried out by many authors, but few have attempted a systematic determination of the parameters that affect masonry at a small scale. The effect of increasing mortar strength and different sand gradings under compression were investigated. The results show masonry strength ...
