This paper presents a literature review concerning the characteristics of MgO (magnesium oxide or magnesia) and its application in cementitious materials. It starts with the characterization of MgO in terms of production processes, calcination temperatures, reactivity, and physical properties. Relationships between different MgO characteristics are established. Then, the influence of MgO incorporation on the properties of cementitious materials is investigated. The mechanical strength and durability behaviour of cement pastes, mortars and concrete mixes made with MgO are discussed. The studied properties of MgO&#;cement mixes include compressive strength, flexural strength, tensile strength, modulus of elasticity, water absorption, porosity, carbonation, chloride ion penetration, shrinkage, expansion, and hydration degree. In addition, microscopic analyses of MgO-cement mixes are also assessed. Summarizing the results of different studies, it is concluded that MgO incorporation in cementitious materials generally decreases the mechanical strength and shrinkage, and increases the porosity, expansion, carbonation and chloride ion migration. However, it should be emphasized that the properties of the specific MgO used (mainly the calcination temperature, the reactivity and the surface area) have a significant influence on the characteristics of the cementitious materials produced.
1. Introduction
The demand for cement and natural aggregates has been exponentially increasing due to rapid construction development. In fact, in , about 40 billion tonnes of aggregates and 4 billion tonnes of cement were required in the construction sector worldwide [1,2]. Consequently, a significant amount of carbon dioxide (CO2) is released to the air during the production stage of these materials. For example, to produce 1 tonne of cement it is necessary to use 125 kW of electricity and to emit about 0.89 tonnes of CO2 emissions to the atmosphere [3,4]. One way to overcome this issue is by incorporating sustainable materials, such as fly ash (FA), silica fume, slag, metakaolin, and recycled aggregates in concrete [5,6,7,8,9,10].
Another alternative approach towards sustainable concrete is through MgO incorporation. Cements with high MgO content gained significant popularity in the last decade, mainly due to the growing concern about climate changes, that is, with the intention and the need to mitigate the CO2 emissions associated with the production of conventional Portland cements. Some authors believe that it is possible to produce such cements, with a high MgO content, with reduced CO2 emissions [11]. Other authors even believe that it is possible to produce cement that has a positive CO2 balance, by capturing atmospheric CO2 to form magnesium minerals (carbonates and hydroxycarbonates). The carbonation of MgO can be described, in general, as the formation of magnesite from MgO, through the absorption of carbon dioxide [11].
The utilization of MgO can, in some conditions of calcination and reactivity, decrease the thermal shrinkage [12,13], reduce the cost of concrete by decreasing costly cooling measures, and accelerate construction process speed by continuously casting concrete without needing as many cold joints [14]. However, the main motivation for the development and upscaling of MgO-based cements was that of an environmental nature. The lower temperatures required for the production of MgO compared to those required for the conversion of CaCO3 into ordinary Portland cement (OPC) and the energy savings associated with that reduced temperature led many to envision MgO-based cements as central to the future of environmentally friendly cement production. Likewise, MgO&#;s ability to absorb CO2 from the atmosphere to form a variety of carbonates and hydroxycarbonates fits well into the discussion of &#;carbon neutral&#; cements, which could absorb almost as much CO2 during its lifetime as that emitted during their manufacture. These two interconnected aspects have led to a recent rise in interest, both academic and commercial, in the area of MgO-based cements.
Currently, research has been focusing on the mechanical and durability-related properties of cementitious materials with MgO. However, an extensive and critical revision based on MgO characterization and properties of MgO-cementitious materials has not been conducted yet. Therefore, the scope of this review is to present MgO&#;s characterization in terms of production processes, calcination temperatures, reactivity, chemical and physical properties and microscopic features, and highlight the influence of MgO incorporation in cement pastes, mortars and concrete in terms of mechanical properties (compressive strength, flexural strength, tensile strength, modulus of elasticity), durability behaviour (water absorption, porosity, carbonation, chloride ion penetration, shrinkage), hydration degree, and microstructural analysis. The authors consider that the existence of a review paper that presents the available results up to date in a structured way will be an important support tool to understand whether or not the use of cementitious materials with MgO as replacement of Portland cement is viable in a given application. On the other hand, through the joint analysis of the existing investigations, it is also intended to understand the extension (percentage) of replacement that can be used and which MgO is best suited to the applications evaluated herein.

First, an initial list of publications was collected, based on several factors: relevance of the title in relation to the topic; cementitious materials type; MgO type; and available data for statistical analysis. For each work collected, an expedient analysis was made in order to establish the relevance of its contents to the research, as well as the tests performed, main outcomes and conclusions. This information was then properly identified and transcribed into a spreadsheet, containing various topics of interest for all publications. As each work was individually evaluated, the relevant data regarding the production of MgO-cementitious material (i.e., cementitious materials type, mix design, curing conditions, etc.) were also collected. Then, an initial table of contents was proposed to serve as a guide for the subsequent investigation. This allowed a comprehensive exploration of the existing information on various factors relating to the use of MgO in the several properties of cementitious materials. As a result, the key points were revealed from the analysis and evaluation data. This allowed drawing several conclusions on the effects of using distinct types of MgO on cementitious materials, and thus enable its use in construction applications.
