Veeger, M.I.A. (author), Ottele, M. (author), Prieto Hoces, A.I. (author)Increased urbanisation will put an increasing strain on our green spaces, which is expected to have a significant effect on our physical and mental health, as well as the health of our ecosystems. As such it is important to integrate more green spaces in our urban fabric. One way of doing this is by making use of so-called bioreceptive concrete...journal article 2021

Lu, T. (author), Li, Z. (author), Huang, H. (author)Shrinkage-induced cracking can impair the durability of concrete structures. In the past few decades, this topic has drawn more and more attention. Shrinkage of mortar and concrete is actually the result of the interaction between the shrinking cement paste and the non-shrinking aggregates. In recent years, different models that consider the...journal article 2021

Pardo Redondo, G. (author), Franco, Giovanna (author), Georgiou, Antroula (author), Ioannou, Ioannis (author), Lubelli, B. (author), Musso, Stefano F. (author), Naldini, S. (author), Nunes, Cristiana (author), Vecchiattini, Rita (author)Historic concrete buildings are at risk. Limited knowledge of concrete technology until the 1960s led to more sensitive buildings than modern concrete buildings. In addition, the lack of sensibility regarding their heritage value and insufficient protection is leading to remorseless demolition. Still, concrete has proved to be a resilient...journal article 2021

Kongshaug, Simen Sørgaard (author), Oseland, Oddbjørn (author), Kanstad, Terje (author), Hendriks, M.A.N. (author), Rodum, Eva (author), Markeset, Gro (author)The alkali silica reaction (ASR) in concrete causes internal localized swelling and micro cracking, which result in expansion and correlated deterioration of the concrete material. The stress state of the concrete is known to affect expansion due to ASR, with an anisotropic stress state giving rise to anisotropic expansion. Similarly, the...journal article 2020

Chang, Z. (author), Zhang, Hongzhi (author), Schlangen, E. (author), Šavija, B. (author)The lattice fracture model is a discrete model that can simulate the fracture process of cementitious materials. In this work, the Delft lattice fracture model is reviewed and utilized for fracture analysis. First, a systematic calibration procedure that relies on the combination of two uniaxial tensile tests is proposed to determine the input...journal article 2020

Liaudat, J. (author), Carol, Ignacio (author), López, Carlos M. (author)Alkali-Silica Reaction (ASR) is a particular type of chemical reaction in concrete, which produces cracking and overall expansion of the affected structural element due to the formation of expansive reaction products within the cracks. This paper develops the formulation of a coupled Chemo-Mechanical (C-M) Finite Element (FE) model for...journal article 2020

Mors, R.M. (author), Jonkers, H.M. (author)Bacteria‐based self‐healing concrete is an innovative concrete that contains a self‐healing agent that provides the material with enhanced autonomous crack‐sealing performance. A specific type of this concrete, based on a healing agent composed of bacterial spores and lactate as carbon source, has been developed and applied by the Delft...journal article 2020

Yu, C. (author)It is difficult to accurately predict the strength of masonry and concrete structures. The most widely used method for simulating their behaviour is finite element analysis with the Newton-Raphson method and arch length control. However, the Newton-Raphson method can diverge and not produce a result, for example in bifurcations or during snap...doctoral thesis 2019

Shamsutdinova, Guzel (author), Hendriks, M.A.N. (author), Jacobsen, Stefan (author)Topography studies of concrete-ice abrasion were made to proceed in our understanding of the mechanisms of concrete wear by ice on Arctic offshore structures. The effects on various initial surfaces of a B75 normal-weight concrete (smooth, rough, sawn) and on the sawn surface of a LB60 lightweight concrete were studied during concrete-ice...journal article 2019

Xiong, Zhihua (author), Liu, Yuqing (author), Zuo, Yize (author), Xin, H. (author)In order to evaluate the shear performance of sand-coated glass fiber-reinforced polymer (GFRP) perforated connectors (SCGPC) embedded in concrete, 8 pull-out tests were conducted. Finite element (FE) analysis considering GFRP failure and cohesion between GFRP and concrete of SCGPC were conducted for parametric analysis. Effects of surface...journal article 2019

Li, Z. (author), Liu, Jiahua (author), Ye, G. (author)This study investigates the drying shrinkage and the shrinkage-induced stress of alkali-activated blast furnace slag and fly ash concrete (AC) in comparison with ordinary Portland cement concrete (OC). For samples that were dried from 1 day after casting, the drying shrinkage of AC was much higher than that of OC. For samples that were stored...journal article 2019

Abambres, Miguel (author), Lantsoght, E.O.L. (author)When concrete is subjected to cycles of compression, its strength is lower than the statically determined concrete compressive strength. This reduction is typically expressed as a function of the number of cycles. In this work, we study the reduced capacity as a function of a given number of cycles by means of artificial neural networks. We used...journal article 2019
