“…For example, the cement industry consumes high energy as well as emits a high amount of CO 2 into the atmosphere [2] , [3] , [4] , [5] , [6] , [7] . The cement industry contributes about 7% of CO 2 production worldwide [8] , [9] , [10] , [11] , [12] , [13] . The laboratory work was conducted through the utilisation of different combinations of these materials in the production of mortar i.e no course aggregate was used in all mixtures.…”

The development in the construction sector and population growth requires an increase in the consumption of construction materials, mainly concrete. Cement is the binder in concrete, so increasing cement production will increase the energy consumed, as well as in the emission of carbon dioxide. This harmful effect of the environment led to the search for alternative materials for cement, as the waste or by-products of other industries is a promising solution in this case. Among these common materials are ground granulated blast furnace slag (GGBS) and cement kiln dust (CKD). This dataset describes the compressive strength and ultrasonic pulse velocity of mortar consisted of high content of GGBS and CKD combinations as a partial substitute for cement (up to 80%) at the ages of 1, 2, 3, 7, 14, 21, 28, 56, 90 and 550 days. This dataset can help the researchers to understand the behaviour of GGBS and CKD in high replacement levels for cement during early (1 day) and later ages (550 days). According to this understanding, the authors believe that the data available here can be used to produce more environmentally friendly mortar or concrete mixtures by significantly reducing the amount of cement used by replacing it with waste or by-products of other industries.

“…About cement production, low-carbon approaches can reduce greenhouse gas emissions by up to 80% (Giesekam et al 2016). The use of recycled materials in concrete production can greatly contribute to the goals of low carbon and circular economics (Nasr et al 2020); it is also important to reduce the cost of concrete production (Mariri et al 2019). One of the techniques to reduce the hazardous impact of PET waste on the environment and reduce the costs of building material is to recycle it as a building material as an alternative to sand or fibers added to concrete (Adnan and Dawood 2020).…”

Recent Studies on Recycled PET Fibers: Production and Applications: a Review

Increasing demand for non-biodegradable plastics undesirably leads to their accumulation and calls for an appropriate solution for this global crisis. Environmental impacts of PET waste have long been addressed; although some remedies have been proposed, their extensive use in the modern world use demands new studies and recycling techniques. It shows the inadequacy of previous solutions to eliminate this environmental problem. Therefore, researching this subject should not be considered an insignificant issue. Distinctively, this review article has a specific reliance on the use of recycled PET fibers in the production of high-consumption and value-added products that, in addition to considering environmental aspects, can also be attractive to the market. This article deals with recent studies in three product categories (concrete, nonwoven fabrics, yarns) made from recycled PET fibers and shows the high potential of PET fibers for the future industry.

“…The strength is 1.04% and 3.39% more. This can be attributed to the fact that the exural strength is more sensitive to changes in the pore structure and the interface transition region between aggregate and cement (Zhang et al 2019;Nasr et al 2020). The highest strength value is 8.54 MPa with M5 on the 28th day.…”

Due to the increasing demand for copper day by day, copper tailings (CT) are the wastes that mining and human-induced activities caused have become a problem all over the world due to the increasing demand for copper. This study evaluates the effect of using CT together with nano silica (NS) and micro silica (MS) in mortars as a partial substitution for cement on mechanical strength properties. Physical, morphological, chemical, mineralogical thermo gravimetric analyzes of CT have been made. In addition, heavy metal concentrations were determined. The mechanical features of the mortars produced by replacing by weight with different proportions of (5%, 10%, 15%) CT, 2% NS and 10% MS cement were determined. As a result, it has been observed that the sum of SiO2, Al2O3 and Fe2O3 of the CT, which has a mostly crystalline structure, is 91.40% and its ignition loss is 4.04%. An improvement in compressive strength (compared to the reference mixture) was observed with the use of 5% CT. Up to 10% of CT has provided standard compressive strength values in both NS and MS combinations.
