“…As desert sand is unsuitable as a building material [5], it has to be mined or dredged from rivers, deltas, and marine and coastal ecosystems, causing environmental damage [6]. At present, the Chinese government's Department of Natural Resources is paying increasing attention to water and soil protection around rivers, and the exploitation and use of natural river sand are subject to many restrictions [7,8]. Artificial sand, creating by crushing stone aggregate, is gradually re-placing natural river sand in the production of concrete [9,10].…”

Due to the depletion of natural sand resources, it is urgent to develop synthetic sand that will replace the natural one in the production of concrete. In this study, we carried out descriptive inspection of mortar working performance, mechanical properties and internal cracking under three different application schemes of fine aggregate, including natural, artificial, and basalt sand. Tests showed that the mortar with river sand had more internal cracking and lowest strength as the temperature rises. The artificial and basalt sand had better resistance and less internal cracking than river sand at high temperature. The compressive strength of basalt sand mortar (BSM) was slightly higher than that of artificial sand mortar (ASM), while the compressive strength value of river sand mortar (RSM) was the lowest at room temperature. However, when heated to 100°C, the RSM had 48% loss of strength, followed by the BSM at 45.4% and ASM at 11.6%. Above 100°C, none of the mortar samples meet the requirement of the calcium sulfoaluminate cement 42.5. The average atomic ratios (Ca/Si, Ca/Al, and Ca/Si) for the ASM and BSM increased with the rise in temperature. XRD showed that above 100°C, the diffraction peaks of Ettringite (AFt) disappeared, the number of CaSO4 diffraction peaks decreased significantly, the intensity decreased, and a diffraction peak of CaCO3 appeared.

Blast furnace slag is a by-product from blast furnaces which is used to produce iron. Blast furnace slag has been used extensively as a successful replacement material for Portland cement in concrete materials to improve durability, produce high strength and high performance concrete, and brings environmental and economic benefits together, such as resource conservation and energy savings. Construction wastes define as relatively clean and heterogeneous building materials which are generated from various construction activities. Among them, ceramic, brick, and marble wastes can be included. These kinds of wastes can be used successfully as replacement materials in the cement mortar or concrete mixing. The use of alternative aggregate is a natural step towards solving part of the depletion of natural aggregate, and the alternative aggregate processed from waste materials which would appear to be an even more sensible solution. Recycled aggregates, such as ceramic, brick, and marble wastes, in the blast furnace slag concrete have been investigated in the limited number of studies to date. In the literature, use of these wastes in the concrete produced by blast furnace slag, as replacement materials in cement have not found adequate attention. Therefore, in the present study, the effects of ceramic, brick, and marble wastes used as fine/coarse aggregates on the properties of blast furnace slag investigated. Thus, the contribution of these wastes on the sustainability of blast furnace slag concrete was presented in a detailed manner. Consequently, construction waste aggregates and blast furnace slag can be used to improve the mechanical properties, workability, and chemical resistance of the conventional concrete mixtures. Since the construction waste and blast furnace slag wastes are available in vast amounts in Turkey, it is economically and environmentally suitable to use these materials as aggregates in the production of more durable concrete mixtures.
