Closed-Form Solution to the Poromechanics of Deep Arbitrary-Shaped Openings Subjected to Rock Mass Alteration
Dong, Xiangjian; Karrech, Ali; Basarir, Hakan; Elchalakani, Mohamed; Qi, Chongchong (Peer reviewed; Journal article, 2020)The aim of this paper is to propose a closed-form solution to the poromechanics problem of stress and pore pressure distribution around noncircular openings at great depth subjected to hydrostatic water pressure and far-field ... -
Development of ECO-UHPC utilizing gold mine tailings as quartz sand alternative
Ahmed, Tanvir; Elchalakani, Mohamed; Basarir, Hakan; Karrech, Ali; Sadrossadat, Ehsan; Yang, Bo (Peer reviewed; Journal article, 2021)To ensure ultra-high performance, in terms strength and durability, coarse aggregate is typically avoided in UHPC (ultra-high performance concrete). Instead, very fine quartz sand is usually used as the only aggregate. ... -
An engineered ML model for prediction of the compressive strength of Eco-SCC based on type and proportions of materials
Sadrossadat, Ehsan; Basarir, Hakan; Karrech, Ali; Elchalakani, Mohamed (Journal article, 2022)Recently, various waste materials and industrial by-products such as supplementary cementitious materials (SCMs) have been proposed to improve the properties of self-compacting concrete (SCC). This profitable waste management ... -
Multi-objective mixture design of cemented paste backfill using particle swarm optimisation algorithm
Sadrossadat, Ehsan; Basarir, Hakan; Luo, Gunhao; Karrech, Ali; Durham, Richard; Fourie, Andy; Elchalakani, Mohamed (Peer reviewed; Journal article, 2020)In order to achieve a successful cemented paste backfill (CPB) mixture design, multiple project requirements such as strength, flowability and cost should be met. For this achievement, the key design parameters, solid ...
