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

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

(author), Wijte, Simon (author)The sustainability of infrastructure projects is becoming increasingly important issue in engineering practice. This means that in the future the construction materials will be selected on the basis of the contribution they can make to reach sustainability requirements. Geopolymers are materials based on by-products from industries. By using...journal article 2019

Bos, Freek (author), Ahmed, Zeeshan Y. (author), Romero Rodriguez, C. (author), Chaves Figueiredo, S. (author)Recent years have seen a rapid growth of additive manufacturing methods for concrete construction. Potential advantages include reduced material use and cost, reduced labor, mass customization and CO2 footprint reduction. None of these methods, however, has yet been able to produce additively manufactured concrete with material properties...journal article 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

Smits, J.E.P. (author), Eigenraam, P. (author), Gkaidatzis, R. (author), Visser, Dirk Rinze (author), Wong, Kailin (author), Wassermann-Fry, Stephan (author)This paper investigates the symbiotic relationship between the architectural appearance of a bridge and the structural design. The research is done by reviewing and comparing the design methodology employed by the first author in the conceptualization of two of his bridges; an early work from 1997 and a recent work from 2017. The review of the...journal article 2018

Shamsutdinova, Guzel (author), Hendriks, M.A.N. (author), Jacobsen, Stefan (author)Concrete structures in the Arctic offshore are often exposed to drifting ice causing abrasion of concrete surfaces. This paper presents the results of a laboratory study of concrete-ice abrasion. The sawn concrete surfaces (two high-performance concrete mixes and one light weight mix of concrete) were exposed to sliding fresh-water ice under...journal article 2018

Esposito, R. (author), Hendriks, M.A.N. (author)The assessment of concrete structures affected by alkali–silica reaction (ASR) is a complex problem due to the multiscale nature of this long-term phenomenon. The reaction starts within the concrete constituents and developed at aggregate level by inducing swelling and deterioration of concrete material, which eventually affect the capacity of...journal article 2017

Qian, Zhiwei (author), Schlangen, E. (author), Ye, G. (author), van Breugel, K. (author)Multiscale modeling for cement-based materials, such as concrete, is a relatively young subject, but there are already a number of different approaches to study different aspects of these classical materials. In this paper, the parameter-passing multiscale modeling scheme is established and applied to address the multiscale modeling problem...journal article 2017

Yang, Z. (author), Polder, R.B. (author), Mol, J.M.C. (author)Owing to the unique molecular structure and high ion exchange capacity, hydrotalcites are believed to have a potential to be modified and tailor-made as an active corrosion protective component of reinforced concrete. In this paper, two types of modified hydrotalcites (MHT-pAB and MHT-NO2) were tested both in alkaline solution and mortar for...journal article 2017

Esposito, R. (author), Hendriks, M.A.N. (author)The alkali-silica reaction (ASR) in concrete is one of the most harmful deterioration processes, which leads to expansion and cracking of the material. To understand the evolution of ASR in concrete and its deteriorating impact on the material, a multiscale material model, from aggregate to concrete level, is proposed. The concrete, which at...journal article 2016

Pacheco, Jose (author), Polder, R.B. (author)Chloride induced reinforcement corrosion is the predominant degradation mechanism affecting reinforced concrete structures. Chlorides (Cl<sup>-</sup>) contained in sea water or de-icing salts penetrate through concrete pores by diffusion and/or convection. Reinforcement corrosion initiates when the Cl concentration at the reinforcing steel...journal article 2016

Wegen, G. Van der (author), Polder, R.B. (author), Breugel, K. Van (author)Nowadays major structures require a service life of 100 years or even more. CUR committee VC81 has developed a guideline for service life design based on initiation of corrosion due to chloride penetration for exposure classes XD or XS. A semi-probabilistic simplification of the DuraCrete methodology is introduced with a probability of failure...journal article 2012
