Experimental Creep Tests on Concrete Made with Montmorillonite Nano Particles

The purpose of this research is to investigate and characterize the time-dependent behavior of new concrete compositions made by replacing cement with secondary aggregates — small clay particles — and then comparing them with control specimens made from ...

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Creep and shrinkage of self compacting concrete: Experimental behavior and numerical model

, 2008
In the present paper, the results of an experimental campaign concerning the rheological properties of hardened self-compacting concrete are presented. Four mixes of self-compacting concrete have been cast, with different compressive strength.

Lattice Discrete Particle Modeling for coupled concrete creep and shrinkage using Solidification Microprestress Theory

, 2015
The macroscopic continuum creep simulation always neglect internal creep/relaxation at lower scales due to the internal self-equilibrated stresses. So far, a comprehensive model for concrete creep at the meso-scale level has been lacking.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

An improved approach for the continuous retardation spectra of concrete creep and applications

Frontiers in Materials
Creep is an important physical property of concrete and can lead to additional displacement, stress redistribution, and even cracking in concrete structures, inducing prestress loss of large-scale prestressed concrete structures.
