“…It has previously been stated that the abrasion resistance of mortars improves with increasing strength (flexural or compression) and compactivity [31], and fly ash and slag can enhance the abrasion resistance of concretes when they replace fine aggregates [32,33]. To understand the performance of hybrid mortars, the relationship between their compression strength and lost volume is shown in Figure 6.…”

One of the most polluting industries is the cement industry and, for this reason, alternative lines of research recommend the use of substitute materials for traditional Portland cement. This study proposes the use of industrial (slag and fly ash) and ceramic wastes for the total or partial replacement of Portland cement in the manufacturing of both alkaline-activated and hybrid cements. To carry out this study and evaluate the behavior of the proposed materials, different mortars were manufactured: Portland cement (CEM I), two alkaline-activated slag systems and six hybrid systems, with an 80–20% waste-to-Portland-cement ratio for all the proposed wastes. An assessment of the pozzolanic activity was carried out for the different materials. The behavior of all the systems regarding mechanical resistance and durability to abrasion was studied. All the proposed materials, especially those with ceramic wastes, showed pozzolanic activity and suitable characteristics for use in the manufacturing of alternative cements. The mortar made of slag activated with waterglass presented the highest mechanical strength and lowest porosity, but the hybrid materials presented competitive results. After being subjected to the Böhme abrasion test, their effectiveness as substitutes for Portland cement is reiterated, some of them improving their durability to wear.

“…Extensive research suggests that the Taguchi method can be well used to detect the effect of various factors on the response as well as predict the results in various issues, both industrial and academic [5][6][7][8][9][10][11][12][13]. In the present research, Taguchi method was used to determine the effect of different parameters on the final price of silk carpet weavers' wages.…”

One of the remarkable phenomena in recent years is the growing trend of globalization. Iran is also seeking to join the World Trade Organization (WTO) to expand non-oil exports and presence in global markets, and is currently a member of the organization's oversight body. Handmade industries such as hand woven carpet are one of the important trades that can be studied for this purpose. Exports of handmade carpets have fluctuated over different time periods. Despite maintaining its international position as the rank of the largest exporter of handmade carpets, the export position of handmade carpets is decreasing as compared to other Iranian exports. Handmade carpet craftsmanship is a complementary activity of agricultural and rural businesses, but due to the considerable number of workers and the small share of carpet value added in the national economy, it does not have a suitable condition. Other influential parameters such as rivals (e.g., China, India, Pakistan, and Turkey), etc. have caused the economic conditions of this industry to be unstable. In this regard, one of the best and most appropriate ways to compete with other countries is to reduce production costs and, consequently, reduce product prices. This factor includes various variables, including weavers' wages. Unfortunately, there is no definite and elaborate program for determining the wages of handmade silk carpet weavers in Iran according to the standard. In fact, in some cities, the weavers' wages determine based on the texture conditions, texture parameters, economic conditions of the country, and other parameters by carpet wage boards that consist of several carpet experts. In this way, there is the possibility of mistakes and the loss of the rights of weavers or producers due to the entry of personal opinion and the failure to classify the effect of different parameters on the final point. The main purpose of this study is to collect various parameters affecting the wages of handmade carpet we

“…In this study, the Portland cement was partially replaced with other admixtures such as fly ash, slag and nano-silica. Sevinc et al [36] tested different mineral additives for improving the durability of concrete and the Taguchi approach was used for reducing the number of experiments and to identify the optimum working conditions. Likewise, Joshaghani et al [37] and Mehta et al [38] made use of the Taguchi method for the optimization of the design of Pervious Pavements and to study the effect of different factors on the compressive strength and water absorption properties of fly ash based geopolymers, respectively.…”
