India has an 8,129 km long coastline. A vast coastal tract faces a serious problem of soil salinity over an area of 3.1 m ha. Most of the coastal salt-affected soils were deficient in nitrogen (N) and zinc (Zn). N availability in coastal soil was lesser associated with poor mineralization by microbes with an increase in soil salinity. Low organic matter, CEC, and light texture encourage the leaching loss of applied nutrients in these soils. It is generally observed that Zn content in soil decreases with an increase in pH. The uptake of N and Zn by plants in saline soils is also affected by the presence of a high concentration of Cl -1 ions. A sustainable strategy to increase nutrient use efficiency in coastal salt-affected soils includes the addition of amendments and balanced use of organic, inorganic, and biological sources of nutrients. Experiments conducted in coastal saline soils which had pH 8.06, EC 2.48 dS/m, and low status of N and Zn, proved the efficacious nature of INM strategy namely 75% NPK + Azospirillum + Phosphobacterium + Zn enriched humic acid @ 20 kg/ha in significantly increasing the availability of Alkaline KMnO 4 -N, DTPA-Zn and improving the N and Zn use efficiency. Another experiment conducted in coastal sodic soil revealed the usefulness of NPK along with 75% ZnSO 4 fortified coir pith/green leaf manure application in increasing Zn use efficiency. A study conducted in coastal sandy on nitrate leaching and its control showed that the application of NPK along with 40 t clay/ ha + 20 kg/ha of humic acid was efficient in increasing the NH 4 -N and NO 3 -N (Nitrate nitrogen) content in soil and improving the N use efficiency.

In this study, an investigation was conducted to assess the influence of nanoscale boron carbide (nB 4 C) particles on the mechanical and tribological properties of AA6063 matrix composites. Using a mechanical stirrer, researchers mixed together AA6063 matrix composites with various amounts of nB 4 C (from 0 to 2.0 wt.%). The experimental results demonstrated that the addition of nB 4 C not only increased the elastic modulus of the material but also led to an enhancement in its brittle behavior, consequently reducing the failure strain significantly. Furthermore, the addition of nB 4 C exhibited notable improvements in the shear modulus and flexural shear modulus of the composites. Notably, the introduction of nB 4 C into the AA6063 matrix resulted in reduced subsurface fatigue wear and increased wear resistance, attributed to the beneficial lubricating properties of B 4 C. Various tests were conducted to evaluate parameters such as wear, micro-structure, morphology, density and voids, hardness, flexural and tensile strength. The results indicated that the addition of nB 4 C led to enhanced wear resistance and tensile strength in the composites. Specifically, the highest wear resistance and tensile strength were achieved with the inclusion of 2 wt.% nB 4 C in the aluminum (Al) metal matrix composite. Microscopical analysis further revealed a consistent and uniform distribution of B 4 C particles throughout the Al matrix, indicating a promising dispersion of the reinforcement material within the composite.
本研究评估了纳米级碳化硼（nB 4 C）颗粒对 AA6063 基复合材料机械性能和摩擦学性能的影响。研究人员使用机械搅拌器将 AA6063 基复合材料与不同量的 nB 4 C（0 至 2.0 wt.%）混合在一起。实验结果表明，添加 nB 4 C 不仅能提高材料的弹性模量，还能增强其脆性行为，从而显著降低破坏应变。此外，添加 nB 4 C 还明显改善了复合材料的剪切模量和弯曲剪切模量。值得注意的是，在 AA6063 基体中引入 nB 4 C 后，表面下疲劳磨损减少，耐磨性提高，这归功于 B 4 C 的有利润滑特性。结果表明，添加 nB 4 C 可增强复合材料的耐磨性和抗拉强度。具体而言，在铝（Al）金属基复合材料中加入 2 wt.% nB 4 C 时，耐磨性和抗拉强度最高。显微分析进一步显示，B 4 C 颗粒在整个铝基体中的分布一致且均匀，这表明增强材料在复合材料中的分散情况良好。

The objective of the research is to compare seashell and eggshell based powder M30 concrete and conventional concrete on the compressive strength. In this study, a total of 18 samples were divided into two groups and prepared for data collection. One is made with ordinary concrete, and the other with seashells and eggshells-based powder M30 concrete. To perform the independent sample t-test, SPSS (Statistical Package for the Social Sciences) software, version 21, was used. The seashell and eggshell based powder M30 concrete sample has a mean compressive strength of 38.00 N/mm 2 , whereas the conventional concrete test sample has a mean characteristics compressive strength of 33.73 N/mm 2 . Independent samples t-test is performed to analyze the results. When a significant difference is found between the two groups in an independent sample t-test and the G-power is 80% and p = 0.053 (p > 0.05), the independent sample t-test is run for both groups is not statistically significant. The standard deviation is 2.90452, 5.81220, and the standard error is 0.68460, 1.36995, with the mean value being 33.7294, 36.8378. From the experimental study results, it could be found that the seashell and eggshell based powder M30 concrete has more compressive strength than traditional concrete.

This study’s primary goal is to increase the strength of plain cement concrete. An effort has been made to research the impact of extra polypropylene fiber in regular Portland cement concrete in an effort to enhance these features of plain concrete. In this experimental investigation, flexural strength tests and flexural strength tests at 28 days for concrete of the M25 grade were conducted to determine the effects of fibers in various percentages (between 3 and 4%). The flexural beam size was taken as 500 mm x 100 mm x 100 mm. According to test re-sults, concrete with polypropylene fiber demonstrates superior performance than concrete without fiber. Comparison of both polymers reinforced concrete beam and conventional concrete beam mean value is (13.0372, 14.4730, and 16.0122), standard deviation is (0.20096, 0.29784), and the standard error is (0.04737, 0.07020). The SPSS (Statistical Package for the Social Sciences) carried out has a significance of 0.000 (p < 0.05). This shows that there is a statistically significant difference between the two groups considered in this study. Fiber insertion much more improves the flexural strength of concrete.
这项研究的主要目标是提高普通水泥混凝土的强度。我们努力研究普通波特兰水泥混凝土中额外聚丙烯纤维的影响，以增强素水泥混凝土的这些特性。在这项实验研究中，对 M25 级混凝土进行了抗折强度试验和 28 天抗折强度试验，以确定不同比例（3% 至 4%）纤维的影响。抗弯梁的尺寸为 500 毫米 x 100 毫米 x 100 毫米。测试结果表明，使用聚丙烯纤维的混凝土比不使用纤维的混凝土性能更优。聚合物加固混凝土梁与传统混凝土梁的比较平均值为（13.0372、14.4730 和 16.0122），标准偏差为（0.20096、0.29784），标准误差为（0.04737、0.07020）。SPSS（社会科学统计软件包）的显著性为 0.000（P < 0.05）。这表明，本研究中考虑的两组之间存在显著的统计学差异。纤维的插入大大提高了混凝土的抗折强度。

The aim of this study is to compare glass powder based M30 concrete to conventional concrete in terms of compressive strength. 18 samples were divided into two groups and prepped for data collection. The first is made using glass powder in place of fine aggregate, and the second is regular concrete. The preparation and examination of the samples involved using a variety of tools and materials. The pretest power is determined with 80% confidence intervals (CI) are 95% respectively. The 20% of glass powder was partially replaced in fine aggregate. Utilizing the universal testing machine, compression strength tests were conducted. The independent sample t-test was carried out using SPSS (Statistical Package for the Social Sciences) software, version 21. The mean compressive strength of concrete with innovative glass powder was 35.4978 N/mm 2 , whereas the typical mean compressive strength of conventional concrete is 34.2744 N/mm 2 . A t-test for independent samples is used to analyze the findings. The significance was p = 0.000 (p < 0.05). This demonstrates that the two approaches have a statistically significant difference. The standard deviation is 1.6697, 2.1529, and the standard error is 0.3935, 0.5074, with the mean value being 34.2744 N/mm 2 , 35.4978N/ mm 2 . From this experimental study, the innovative glass powder based M30 grade concrete is found to have a higher compressive strength than regular concrete, it is determined.
