Numerous waste materials containing calcium and silica have been adopted as partial cement substitutes. This practice is intended to reduce the environmental impact of cement production, specifically in terms of carbon dioxide (CO2) emissions. However, plantation waste, specifically waste from Cymbopogon nardus leaf, has not been completely exploited. The presence of silica in C. nardus leaf ash (CNLA) presents an opportunity to partially replace cement in concrete. The purpose of this study is to determine the effect of substituting CNLA at 0%, 5%, 10%, and 15% as a partial replacement for cement on the compressive and tensile strengths of concrete after 28 days of curing. For testing purposes, 15 cm × 30 cm cylindrical concrete specimens were formed. The investigation was conducted following ACI 211.1-91 (American Concrete Institute) and ASTM (American Society for Testing and Materials) standards. The required compressive strength for the concrete was 17.00 MPa. The results of the study indicate that the addition of CNLA to cement at concentrations of 0%, 5%, 10%, and 15% resulted in compressive strengths of 21.56, 21.12, 22.58, and 17.88 MPa, respectively. The results of the split tensile strength test were 2.43, 2.72, 2.87, and 3.18 MPa, respectively. According to the findings of this study, increasing the amount of CNLA in cement by 10% can increase the compressive and tensile strengths of concrete. In addition, as the percentage of CNLA exceeds 10%, the workability of the concrete decreases, posing challenges in attaining the targeted strength of the concrete.

The therapeutic potential of Kunzea ambigua essential oil is experiencing increased market demand. However, commercial production is currently limited by variability of wild-harvested feedstock so that managed production from high yielding clones is desired. This study explored the utility of near infrared (NIR) reflectance spectroscopy to predict total extracted oil and the major terpenes from intact and ground K. ambigua leaves. Partial least squares regression enabled accurate prediction of total extracted oil and the concentration of α-pinene, globulol and viridiflorol but not α-terpineol (the major components). This was the case for both ground and intact leaf samples, though the coefficients of determination (r2) values were lower for the intact leaf samples (r2: 0.59 to 0.71, ratio of residual prediction to the deviation, RPD: 1.4-5.0, RMSEP: 0.53-2.27 mg/g) as compared to the ground samples (r2: 0.72-0.88; RPD: 1.9-8; RMSEP: 0.32-1.40 mg/g). In contrast, a NIR predictive model was produced for ground but not intact samples for 1,8-cineole (r2: 0.72; RPD: 1.9; RMSEP: 0.42 mg/g). Though the predictive models developed in this study were less accurate and less precise than for the intact samples, this technology could still be immediately useful and allow for rapid identification and screening for superior K. ambigua genotypes from native vegetation for both total extracted oil and preferred chemical profiles.
