“…Even with a 100% CSA substitution, Prem et al [42] reported that there was improved water absorption by increasing the W/C ratios to 0.37, 0.47, and 0.57. The water absorption value decreases in concrete mixtures, adding up to 15% of CSA as a cement substitute [43]. However, the value increased when the replacement was greater than 15%.…”

“…Rajasekar et al [67] found an extremely low chloride ion penetration in UHSC containing up to 60% CSA. The CSA, on the other hand, did not appear to have a significant impact on the chloride ion penetration values of concrete mixtures in several studies [43]. According to ASTM C1202 [62], the chloride ion penetration values of concrete mixes including CSA were classified as low and very low.…”

“…A matrix with 100% of CSA as a fine aggregate substitution was regarded as a suitable solution by Prem et al [42]. Afshoon and Sharifi [43] investigated the strength and toughness of SCC mixes with CSA as a cement replacement from up to 30% with a five percent increase. The utilization of CSA up to 15% in place of cement produced better or equivalent results.…”

Recycling trash and protecting natural resources are two of the many benefits of using copper slag as a fine aggregate in a concrete building. However, stakeholders need proven research output to build trust and initiate or enhance the use of such industrial waste in buildings. This study evaluated self-compacting concrete’s fresh and hardened characteristics (SCC) comprising a copper slag aggregate (CSA). For this purpose, six mixes were prepared by substituting river sand with CSA up to 50%, with a 10% increment. The properties of fresh SCC were evaluated using slump flow, V-funnel, and L-box tests. Several parameters of SCC were examined, including water absorption, sorptivity, chloride ion penetration, sulphate attack, and acid attack tests. Energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM) were used to investigate the concrete microstructure. The results indicated that the fresh characteristics of SCC were enhanced as the amount of CSA increased consistently. The durability properties showed a considerable enhancement in SCC mixes comprising up to 20% of CSA.

This research work is aimed to carryout experimental investigation on copper slag incorporated self-compacting (SCC) concrete; here, copper slag is used as a replacement to fine aggregate in the range of 0-100%. The self-compacting concrete is manufactured with powder matrix incorporating cement, flyash, metakaolin, and silicafume. The powder matrix is decided based on the objective of flow properties and strength properties. The fresh concrete properties of various mixes were studied and collected. Then, the concrete is casted as cubes and cylinders and tested for its strength behavior. The flow properties of copper slag-replaced mix were within stipulated guideline values by EFNARC, and early age strength attainment gets affected by the replacement of copper slag. The collected experimental results were designed to a data set categorizing as input and target. This data set is then used as a parameter in feed forward artificial neural network (ANN) and a predictive model is developed. This predictive model is then compared with the existing experimental values and tested for its performance. The results show that ANN provides a reliable predictive model for both flow and strength properties.

“…There is only one report regarding the EO composition of D. aucheri fruits. [14] Most of the previous studies on this plant have been focused in the medical field including its toxicity and carcinogenicity, [4] [15] induction of mammary gland tumors, [16] the regulation of blood concentration [17] and its analgesic and anti-inflammatory effects. [18] Furthermore, there are few studies in respect to its antioxidant activity.…”

In the present research, variability in essential oil (EO) composition of five Dorema aucheri populations collected from natural habitats in different regions of Iran, were investigated. The EO content of populations varied from 0.28 to 0.68%. According to gas chromatography/mass spectrometry analysis, β-caryophyllene (7.17 - 35.73%), thymol (23.45 - 29.64%), β-gurjunene (2.58 - 5.89%), carvacrol (1.32 - 2.67%) and cuparene (1.97 - 2.98%) were the major components. Hierarchical cluster, principal component and canonical correspondence analyses classified the studied populations into three groups based on major EO components. The environmental parameters of the collected sites were also evaluated. According to the results, it might be suggested that sandy soils with high mean annual precipitation were major environmental factors influencing the amount of β-caryophyllene, while thymol, cuparene and caryophyllen oxide increased in silty and clay soils. Finally, the population collected in high altitudes and clay soils had higher amount of β-gurjunene.
