This paper brings a new insight into understanding the influence of macrocapsules in packing systems, which can be useful designing inert structure self-healing concrete. A variety tubular macrocapsules, terms types and sizes, was used to assess capsules' effect packing, together with various aggregate fractions. The voids ratios (U) mixtures were evaluated experimentally compared prediction via particle model Dewar. coarse particles found considerably affected by presence while no on fine...
The use of macrocapsules in self-healing applications offers a potential benefit by carrying larger amount healing agent comparison with microcapsules. However, the application is still limited to paste and mortar levels on lab-scale. This due concern that most capsules might be broken when mixed concrete components. In this study, cementitious tubular were used they considered as partial replacement coarse aggregates (2 vol% gravel). have dimension 54 mm 9 length outer diameter,...
Facing the aging building stock, challenging times can be expected with a sharp increase of reinforced concrete buildings requiring maintenance, repair and/or replacement. For condition assessment existing structures an in-depth and reliable inspection strategy evaluation is essential to come durable service-life extending strategy. A stepwise protocol evaluate remaining bearing capacity cantilevered (RC) balconies presented in this paper. Corrosion causing reduction steel section, incorrect...
<p>This contribution presents the preliminary research outcomes of a pilot program for validation models and test methods assessment durability related to Belgian concrete mixtures. The chloride diffusion carbonation model of<i>fib</i>bulletin 34 [1] recent reported in<i>fib</i>bulletin 76 [2] are applied evaluated. A sensitivity analysis is performed both damage mechanisms. In addition there certain parameters in which can be recalibrated compositions or...
Particle packing models (PPMs) have been developed and evolved since 1929 allow to formulate the proportioning of concrete mix constituents with minimal voids ratio.In past, this tool has led important innovations in technology, as development ultra-high performance concrete.Also regard design ecological concrete, PPM is a promising technique.In our ongoing research on incorporating recycled aggregates (RCAs), model Dewar will be applied.This theory however mainly validated for mixtures...
