Predicting damage in aggregates due to the volume increase of the alkali-silica reaction products

E. R. Gallyamov et al.

Summary: This paper studies the possibility of crack growth due to internal loading caused by alkali-silica reaction. The study reveals the dependence of crack growth potential on the shape of the ASR product, particularly spherical and spheroidal shapes. For a chosen material properties and expansion value, there exists a critical spheroid radius below which no crack growth is expected.

Alkali-silica reaction products and cracks: X-ray micro-tomography-based analysis of their spatial-temporal evolution at a mesoscale

Mahdieh Shakoorioskooie et al.

Summary: In this study, a laboratory-scale methodology using X-ray micro-tomography and cesium as a contrast agent was proposed to advance the understanding of cracking due to alkali-silica reaction (ASR) in concrete. The addition of cesium slightly accelerated the ASR kinetics, but the crack patterns with and without cesium were statistically equivalent. The study also found that ASR products may initially be a low-viscosity gel that can flow away from the source aggregate and settle later elsewhere as a rigid phase upon calcium uptake.

A multi-surface interface model for sequentially linear methods to analyse masonry structures

M. Pari et al.

Summary: In the finite element modelling of masonry structures, a numerically robust sequentially linear solution procedure and a suitable discretised tension-shear-compression failure model for interfaces are proposed to simulate the cracking-crushing-shearing failure possibilities in masonry. The applicability of these formulations are illustrated using 2D and 3D models in a pushover analysis on a squat unreinforced masonry wall, reproducing the experiment results in a stable manner.
