## 1 Introduction  
One of the most widely used products in the world today are aggregates, specifically sand and gravel, which are used in the construction of buildings in the preparation of concrete or other types of mixtures. In fact, after water, concrete is the most consumed product on the planet and is directly related to the level of development of countries. This material is used not only for the construction of new civil/architectural works but also for the repair, rehabilitation, and/or reconstruction of existing works. Therefore, there is evidence of an increase in the generation of concrete waste related to the construction process and demolition activities (concrete, brick, masonry, tiles, and ceramic materials) that are related to population growth and the modernization of regions [1, 2]. The development of civil work generates a large amount of waste that can be reused. In the first case, the best scenario would be reusing the waste as fillers for the development of new civil works and, in the second case, they are disposed of in municipal landfills, which results in competing for space with municipal solid waste when managed in the same facilities [3] or inadequately abandoned, generating an environmental impact due to the loss of landscape quality in the different localities and environmental pollution [4, 5]. This is without taking into consideration the significant volume of debris generated annually as a consequence of natural disasters and wars, which additionally increases the costs of waste and debris management [6, 7]. For example, the waste management costs of Hurricane Katrina exceeded $4 billion [8]. In terms of numbers, it can be noted that: (1) For the year 2010, 36% of waste worldwide corresponded to construction and demolition [8, 9]; (2) the global average generation of special construction and demolition waste worldwide corresponds to 1.68 kg/capita/dayin 2018. Based on this reality, researchers and specialists from universities and research and quality control centers around the world have focused on providing management solutions. Likewise, several countries have, at the legislative level, adopted the promotion and provided incentives to reuse waste; which has been reflected in the statistics. The amount of waste recovered in the EU has been increasing; it has increased from 45.4% in 2014 to 53.2% in 2018. In the EU, 37.8% of the waste generated in 2018 was recycled, 9.9% used as landfill, and 5.6% used for energy recovery. The remaining 46.8% was landfilled (38.8%) and incinated without energy recovery (1.0%) or otherwise disposed of (7%). In this context, the European 2020 Strategy establishes the following objectives for waste policy in all member states: (a) reduction in waste generated; (b) increase in recycling and reuse; (c) limitation of incineration; (d) limitation of the use of landfills [10; 11]. With these premises, the need for waste management policies that reduce environmental and health impacts and improve the efficiency of available resources is clear. The long-term goal is to turn the world into a recycling society by avoiding waste and using waste as a resource wherever possible. The aim is to achieve much higher levels of recycling and minimize the extraction of additional natural resources. Currently, there are numerous studies that support the use of construction and the demolition of waste in the production of recycled concrete [12; 13; 14; 15; 16; 17; 18; 19; 20; 21; 22; 23; 24; 25; 26; 27; 28; 29; 30] and recycled mortars [31; 32; 33; 34; 35; 36; 37; 38; 39; 40; 41; 42; 43; 44; 45; 46; 47; 48; 49]. However, despite the upward trend in the reuse of demolition waste, it has been shown that the use of recycled aggregate materials can limit or decrease the properties of concrete (strength, durability, and service capacity) due to old bonded mortar, irregular shapes, and increased porosity. In other words, there is a direct dependence between the properties of concrete and the degree of substitution used with recycled aggregates [50; 51; 52].
