Guo, Bingbing (author), Li, Z. (author), Fu, Qiang (author), Wang, Yan (author), Huang, Daguan (author), Niu, Ditao (author)Utilizing coral aggregate concrete (CAC) for construction on remote islands can significantly reduce construction cost and period, CO<sub>2</sub> emission, and consumption of non-renewable energy. The durability of reinforced CAC structures is critically influenced by their resistance to chloride attack. In this study, a reactive transport...journal article 2021

Li, Z. (author), Lu, T. (author), Chen, Y. (author), Wu, B. (author), Ye, G. (author)This study aims to predict the autogenous shrinkage of alkali-activated concrete (AAC) based on slag and fly ash. A variety of analytical and numerical models are available for the prediction of autogenous shrinkage of ordinary Portland cement (OPC) concrete, but these models are found to show dramatic discrepancies when applied for AAC due...journal article 2021

Zhang, Hongzhi (author), Yuan, Huaqiang (author), Ge, Zhi (author), Wu, Jiajie (author), Fang, Cheng (author), Schlangen, E. (author), Šavija, B. (author)Clay brick is one of the major components of demolition waste, which is generally landfilled. Effective and new uses of recycled clay brick may provide sustainability benefits in terms of landfill reduction. Therefore, this research aims at applying Recycled fine clay brick aggregates (RFCBA) with sizes from 0.075 mm–4.75 mm to prepare Self...journal article 2021

Kebriaei, Hamed (author), Sadati-Savadkoohi, S. Jafar (author), Shokri, Mohammad (author), Grammatico, S. (author)In this article, we extend the theory of deterministic mean-field/aggregative games to multipopulation games. We consider a set of populations, each managed by a population coordinator (PC), of selfish agents playing a global noncooperative game, whose cost functions are affected by an aggregate term across all agents from all populations. In...journal article 2021

Del Pia, Alberto (author), Gijswijt, D.C. (author), Linderoth, Jeff (author), Zhu, Haoran (author)An integer packing set is a set of non-negative integer vectors with the property that, if a vector x is in the set, then every non-negative integer vector y with y≤x is in the set as well. The main result of this paper is that integer packing sets, ordered by inclusion, form a well-quasi-ordering. This result allows us to answer a recently...journal article 2021

Okur, Ö. (author), Heijnen, P.W. (author), Lukszo, Z. (author)Flexibility coming from consumers in residential and service sectors has received significant attention to deal with uncertainty and variability of renewable energy sources. Since these consumers are too small individually to participate in the electricity markets, their assets can be pooled by an aggregator. The aggregator can implement...review 2021

(author), Wei, Jiangxiong (author), Yu, Qijun (author)Non-uniform stresses, strains and microcracking of the concretes with three coarse aggregate sizes (5–10 mm, 10–16 mm, 16–20 mm) dried under 40% relative humidity (RH) for 60 days were quantified using digital image correlation and lattice fracture modelling. The influencing mechanism of coarse aggregate size on the drying-induced...journal article 2021

Qiu, Xiujiao (author), Chen, J. (author), Deprez, Maxim (author), Cnudde, Veerle (author), Ye, G. (author), De Schutter, Geert (author)The microstructure of alkali-reactive aggregates, especially the spatial distribution of the pore and reactive silica phase, plays a significant role in the process of the alkali silica reaction (ASR) in concrete, as it determines not only the reaction front of ASR but also the localization of the produced expansive product from where the...journal article 2021

Tindemans, Simon H. (author), Strbac, Goran (author)Thermostatically controlled loads such as refrigerators are exceptionally suitable as a flexible demand resource. This article derives a decentralized load control algorithm for refrigerators. It is adapted from an existing continuous time control approach, with the aim to achieve low computational complexity and an ability to handle discrete...journal article 2021

These protocols can be extended with zero-knowledge proofs and commitments to work in the malicious model, but this incurs a significant computational cost on the end users, making adoption...conference paper 2021

Pan, L.Y. (author)Porous asphalt resides on most top layers of Dutch roads. Scheduling maintenance for these roads is generally dependent on several factors, but ravelling, the loss of aggregates in the top layers, is the main reason for maintenance on Dutch roads. With the recent framework of the DOS-LCMS scheme generating values for aggregate loss in...master thesis 2020
