“…These percentages vary between 0% and 30% of the total fine aggregate volume. Given also the differences in water absorption and our objective being to obtain mortars with a constant consistency, class S2, according to UNE-EN-12350-2 [54], the amount of water is modified as the amount of GOS increase [49]. These amounts of water for each mortar sample can be seen in Table 4 and vary according to the doping percentage of the mortar.…”

“…This fact is reported in the research carried out by Ferreiro et al, where they evaluate the mechanical and physical characteristics (density, compression, and flexural strength) of GOS-doped mortars with different CEM II cements. For the specific case of using CEM II 32.5R, they indicate a GOS use range of 0-30% [49]. For this reason, only a range of GOS use in mortars of 0-30% is studied in this research.…”

“…However, in contrast to the study by Barraca et al, in this research, the doping range (0-30%) is considerably narrowed down, studying within this interval the possible variations that exist in small increments (5%) in order to obtain a series of data with the smallest possible deviation. In addition, considerations in terms of the mechanical strength (compression and bending) of the mortars were taken into account [49]. In order to find out whether these doped mortars have a minimum of structural safety for their application to prefabricated elements, the heat transfer capacity (thermal conductivity) is analysed in the various samples and tested in a laboratory using a machine designed to measure the thermal conductivity of different construction materials.…”

The aim of achieving sustainability in construction is a reality. A useful strategy to achieve this is the use of waste from agricultural activities. This waste could reduce the environmental impacts associated with the production of raw materials such as natural aggregate, reducing energy consumption from fossil fuels and therefore CO2 emissions. This study examines the thermal conductivity of mortars doped with ground olive stones, a residual by-product of industrial processes. The objective is to evaluate the potential of ground olive stones to improve thermal insulation in construction. Ground olive stones are used as a partial replacement for the aggregates used in mortar bricks. The methodology followed herein to quantify the benefits of this product involves creating several types of mortar with a different percentage of ground olive stones in each sample (between 0% and 30%). Thermal conductivity was determined according to UNE-EN12939:2001. Finally, a case study is conducted performing an energy simulation of a residential building to determine the energy savings derived from reducing the combined thermal demands of heating and cooling and to analyse the feasibility of the alternative use of ground olive stone residue doped in mortar bricks for new sustainable façades. The results show a saving in energy demand (heating and cooling) of 0.938 kWh/m2·year when using 30% GOS-doped mortar bricks compared to the reference bricks. This is equivalent to a decrease in energy demand of 2.23% per square meter of façade. In addition, these annual energy savings are compared to the potential thermal energy created from the combustion of ground olive stones in a biomass boiler, which is the main traditional use of this waste today. It reveals that for a doping range of 5–15%, the recovery time ranges between 30 and 75 yeas, which is within the lifetime of a building. The results demonstrate the great viability of using ground olive stones as fine aggregates in mortars and their possible application in sustainable construction, in particular in more sustainable façades that allow energy savings in buildings and therefore a lower consumption of fossil, which will make it possible to reduce greenhouse gas emissions and the excessive consumption of resources.

Concrete is the most commonly used and dependable substance and the most consumed among all other construction materials. However, the construction industry’s insatiable need for building supplies has led to the widespread exploitation of natural resources like river sand and stone. However, one of the most pressing problems in the construction industry and others nowadays is excessive waste and byproducts. Promoting ecological control and the goal of sustainable progress has put environmental pressure on all businesses, including construction, to embrace eco-friendly practices. Environmentalists’ concerns about the dangers posed by the widespread use of natural resources in building construction are growing. In some instances, construction debris may be harmful to the environment. Global building growth and redevelopment plans have worsened demolition in the construction industry. The demand for construction materials is increasing yearly due to urbanism, but their costs are rising simultaneously. Using industrial waste like polymers and rubbers and natural waste like olive stones and pumice stones to replace cement, fine aggregate, and coarse aggregate to reduce building costs conserves natural resources from exhaustion and protects the environment from waste impact and risks. The current research shows how waste can be used to replace materials on construction sites and the impact of the properties of these materials on the quality of concrete.

“…For all nations to contribute to sustainable development, the use of waste in concrete and cement products has become a must [1]. There have been numerous materials employed, including recycled aggregates [2,3], olive stones as a lightweight aggregate in mortars [4], steel slag as a coarse aggregate in concrete, and mortars doped with crumb rubber from used tires [5]. Steel slag is a by-product of the steel industry and is a type of waste.…”

The aim of this study is to compare the properties of refractory concrete made with thermally treated and untreated steel slag. Five concrete compositions were prepared and investigated in the present work. The first mixture, referred to as the reference, was formulated using dolomite aggregates, whereas the second and third mixtures were developed by replacing natural coarse aggregate with 50 and 100% by weight of thermally untreated steel slag, respectively. The same replacement ratio (50% and 100%) of thermally treated steel slag was used to produce the fourth and fifth mixtures. Specimens of each specimen were placed in a furnace and heated to 400 °C and 800 °C. The mass loss for all the specimens heated to 400 °C was about 8%, while the reference suffered the maximum mass loss at 800 °C, which was 21.6%. The mixture with a 100% substitution of thermally treated steel slag produced the maximum compressive strength when compared to other mixtures at a temperature of 800 °C. The compressive strength of the M5 mixture was 18 MPa versus 10.87 MPa for the reference mixture. Additionally, optical microscope examination of specimens containing thermally treated steel slag revealed less damage than that observed in mixtures with dolomite.
