“…Experimental results established by Alwaeli and Nadziakiewicz [7] proved that the shielding effect of concrete with different proportions of scrap steel chips on gamma rays is superior to the ordinary concrete with natural sand. Onoue et al [8] investigated the fatigue properties of slag concrete and derived the equations for calculating its fatigue life by the theory of fatigue mechanics. A series of laboratory experiments on the mechanical behavior of concrete prepared by abandoned iron ore tailings in Iraq was carried out by Ismail and AL-Hashmi [9], and results revealed that its performance was superior to ordinary concrete and exhibited higher compressive strength and flexural strength.…”

The objective of this study is to evaluate the modified performance of concrete with mixing of iron ore tailings in order to solve the shortage of natural sand and make full use of industrial waste. Firstly, the raw materials of mixing were analyzed, and the test ratio was determined. Secondly, the workability and mechanical property of concrete specimens with different amounts of iron ore tailings as replacement were tested. Results show that 35% replacement of natural aggregate by iron ore tailings is optimal. Finally, tests of impermeability, frost resistance, and carbonation resistance were further performed for the concrete specimens with optimal amount of iron ore tailings. The compression performance of the specimens after a durability test was determined. The change in the mechanical properties of the specimens was obtained after seepage, freezing-thawing, and carbonation. Findings showed that the performance of the concrete with 35% replacement of iron ore tailings is basically equivalent to that of natural sand concrete. Hence, it can be utilized in engineering applications.

“…A recent study shows that the durability of recycled concrete depends on the quality of the RA and that the most suitable RA comes from precast-structural concretes [2]. Also, several studies have analysed the behaviour of RC under cyclic stress (fatigue) [5][6][7][8], showing that the negative effect of the incorporation of recycled aggregate is significantly higher in the case of dynamic rather than static conditions. Other authors have found solutions, using other recycled materials, to improve the properties of the cement paste.…”

Advances in Construction and Demolition Waste Recycling

The search for ways of using recycled aggregate (RA) from construction and demolition wastes (C&DW) in the production of recycled aggregate concrete (RC) has been going on for many years. Most researchers agree about the reduction in the physical and mechanical properties and the durability [1]. However, there are no comparable results on the durability of RC exposed to marine environments due to the heterogeneity of the RA, the w/c ratios and the types of cement used in different countries. Different studies [1][2][3][4] show that permeability, carbonation and risk of reinforcement corrosion increase when RC is used. However, no information is found in the literature about how the w/c ratio and capillary network affect the durability of RC exposed to a marine environment. A recent study shows that the durability of recycled concrete depends on the quality of the RA and that the most suitable RA comes from precast-structural concretes [2]. Also, several studies have analysed the behaviour of RC under cyclic stress (fatigue) [5][6][7][8], showing that the negative effect of the incorporation of recycled aggregate is significantly higher in the case of dynamic rather than static conditions. Other authors have found solutions, using other recycled materials, to improve the properties of the cement paste. Using this method, the effect of the RA [9] can be minimised, not only in nocement but also in polymeric matrixes [10]. The use of RA containing contaminants such as sulphur and properties of recycled aggregate mortar (RAM) and RC has also been studied [11], finding a reduction in the quality of the concrete proportional to the quality of the recycled aggregate. This paper presents the results of a study of permeability and its influence on the durability of recycled concrete exposed to an aggressive environment. On the one hand, the effect of RA on concrete properties has been analysed by studying the same w/c ratios and, on the other hand, the influence of the w/c ratio and its capillary network has been measured for equivalent degrees of RA. With this aim, RC with 20%, 50% and 100% wt of RA and 24 effective w/c ratios have been exposed directly to a marine environment.

“…No mesmo ano, Onoue et al (2014) avaliaram a fadiga à compressão em concretos produzidos com cimentos convencional e com adição de escória de alto forno. Os autores conduziram ensaios experimentais, simulando cargas cíclicas referentes aos componentes estruturais a qual aquele concreto seria aplicado, isto é, em estruturas marinhas e portuárias.…”
