The results of an experimental study conducted to evaluate the material characteristics of ternary blended concrete containing Nano-alumina and Zeolite along with polypropylene fibres to act as micro-reinforcement has been presented in this paper. The optimum combination of nano-alumina and zeolite has been obtained through preliminary studies. The beams were cast with concrete containing 1% Nano-Alumina and 10% Zeolite having PPF fibres in three-volume fractions (0.1, 0.2 and 0.3%). Six beam specimens of overall dimensions 150mm x 250mm x 3000mm were tested for their flexural capacity in a standard loading frame. One beam was made out of control concrete. The remaining five beams were made with ternary blended concrete with and without micro-reinforcement. The beam specimens were examined for their behaviour under static loading conditions. The performance of the beam specimens was assessed in terms of first crack load, deflection at first crack load, yield load, deflection at yield load, ultimate load, deflection at ultimate load, deflection ductility, and deflection ductility ratio, energy ductility and energy ductility ratio. The Inclusion of polypropylene fibres increased ultimate crack load by 40%, decreased deflection by 84.17%, decreased crack width by 45.45%, decreased crack spacing by 55%, increased deflection ductility by 34.31%, increased energy ductility by 84.38% and increased energy capacity by 151% compared to the control concrete beam.

This study analyses the effect of social capital on competitive advantage in Saudi Arabia's travel and tourist businesses. This study employs a survey methodology to collect data from deputy directors, heads of departments, and employees in the travel and tourism businesses in the Al-Kharj Governorate. 250 employees comprise the final sample. This study reveals that travel and tourist organisations have a high level of internal social capital and achieve an increased competitive advantage when using descriptive statistics and simple and multiple regressions. Additionally, this study discovers a positive and statistically significant relationship between internal marketing and competitive advantage. This study proposes that travel and tourism businesses develop an internal social capital department due to the critical role of social capital in strengthening these organisations' competitive advantages.

In this study, the influence of crumb rubber on the properties of geopolymer mortar was investigated. The crumb rubber was used as fine aggregate to reduce consumption of natural river sand. The rubber replacement levels namely 10%, 20%, and 30% by volume of the sand was chosen. The results were compared with the control specimen made with only river sand. It was found that the compressive strength of mortars was decreased with increasing the crumb rubber content. An increase in water absorption was observed. However, the strength of the paving block specimen made with 10% rubber meets the requirements for application in interlocking paving blocks. Its compressive strength at the age of 7 days was 85.0 MPa. Disciplinary: Civil Engineering & Material Technology (Cement, Geopolymer, Construction Materials, Pavement).

Recently, various optimization methods are being used in the design process in order to find the optimized form of products under different given conditions. The use of topology optimization has enabled engineer designers and industrialists to achieve lighter-weight products costeffectively and at less time-consuming processes without losing their intended design purposes. In this study, topology optimization using Autodesk Inventor Software is applied to a component of a front-end telescopic hydraulic cylinder to reduce the mass by at least 30% of the original weight while satisfying the pressure constraints of 18 MPa. Furthermore, sketches are drawn based on the forms derived from topology optimization and the final design is generated into CAD. Finally, finite element analysis is done upon the final model in order to conduct the durability analysis. The results show that the model of the component obtained with topology analysis has been reduced by 30.77% of the original weight while ensuring normal operation under the given constraints.
