Special Issue Information

Dear Colleagues,

Concrete has always been indispensable as a material for engineering construction of hydraulic structures. Hydropower resources are often distributed in alpine regions, which are characterized by a complex terrain, large climate changes, and frequent extreme weather. Such a harsh environment undoubtedly poses new challenges for the durability of hydraulic concrete, which is easily damaged by various environmental factors. In fact, concrete often fails before reaching its designed service life due to these environmental factors. This is not the only issue facing the industry: Recent changes in the general green awareness have meant that the development of sustainable hydraulic concrete is now inevitable. One of the main features of sustainable hydraulic concrete is reducing, as much as possible, the amount of cement used and utilizing a large amount of admixture. As hydraulic concrete is a typical mass concrete, admixture content in it may be as high as 70% or even more, perhaps leading to low strength and unsatisfactory durability. The macroscopic properties of hydraulic concrete are considerably affected by its microstructure. Therefore, it is also necessary to quantitatively describe the microstructure characteristics of hydraulic concrete.

The Special Issue invites contributions on the topic of sustainable high-performance hydraulic concrete, including but not limited to the investigation of durability, preparation, and microstructure of hydraulic concrete. We welcome both original research articles and review articles.

Magnesium oxychloride cement (MOC) foam concrete (MOCFC) is an air-hardening cementing material formed by mixing magnesium chloride solution (MgCl2) and light-burned magnesia (i.e., active MgO). In application, adding caustic dolomite powder into light-burned magnesite powder can reduce the MOCFC production cost. The brine content of MOC changes with the incorporation of caustic dolomite powder. This study investigated the relationship between the mass percent concentration and the Baumé degree of a magnesium chloride solution after bischofite (MgCl2·6H2O) from a salt lake was dissolved in water. The proportional relationship between the amount of water in brine and bischofite, and the functional formula for the water-to-cement ratio (W/C) of MOC mixed with caustic dolomite powder were deduced. The functional relationship was verified as feasible for preparing MOC through the experiment. Full article

In this research, we developed a four-phase model, which takes the aggregate gradation and porosity into account in the prediction of the elastic modulus of concrete, based on the micromechanical theories. The model has been verified with experimental results. First, using the Mori Tanaka and the differential self-consistent (DSC) methods, the pores in both the mortar and interfacial transition zone (ITZ) were homogenized. Then, the continuously graded aggregates were divided into finite aggregate size intervals. Further, using the generalized self-consistent model and multiphase composite model derived from the Mori Tanaka method, an aggregate gradation model for the prediction of the elastic modulus of concrete was developed. By simulating the pores in concrete with expanded polystyrene sphere (EPS) grains, the effect of overall porosity on the elastic modulus of concrete was investigated. The research results show that aggregate gradation and porosity have remarkable influence on the elastic modulus of concrete, and the proposed model is effective to estimate the elastic modulus of concrete, the deviation between the predicted elastic modulus and experimental elastic modulus is less than 8%. The elastic modulus decreases with increasing ITZ porosity. However, for ITZ porosity exceeding 40%, the decrease in the elastic modulus is large with increasing ITZ porosity. For a fixed overall porosity, the ITZ porosity owned more influences than the mortar porosity on the elastic modulus of concrete. Enhancing the ITZ elastic modulus and decreasing the ITZ thickness are efficient in increasing the elastic modulus of concrete. Full article
