The objective was to compare the use of M30 grade concrete admixture to partially replace coarse aggregate in lightweight concrete with a novel pumice aggregate using conventional concrete. Two groups prepared in 70% cement mixture and instead of 20% silica fume, 10% metakaolin was fixed in this concrete. Novel pumice was used as coarse aggregate and M-sand as fine aggregate. An independent t-test was calculated using 80% G-power. Metakaolin and silica fume are purchased from scientific institutes and novel pumice is arranged from online traders. Results: The group of 18 cubes was formed according to the curing date for 28 days. A total of two groups were prepared and a total of 36 cubes were prepared to find the compressive strength. The independent sample t-test on two groups showed that there was a statistically significant difference with p < 0.000 (p < 0.05). This represents group statistics for a sample group of 20% silica fume and 10% of metakaolin and novel pumice stone as coarse aggregate. mean (34.3311, 36.8061), standard deviation (1.65492, 1.58424), and standard error mean (0.39007, 0.37341). The average M30 grade of concrete at 28 days of compressive strength test result of conventional concrete is 34.33 N/mm 2 . The M30 Grade of concrete at 28 days of compressive strength test result of concrete with novel pumice stone and partial replacement of silica fume and metakaolin by the weight of cement is 36.80 N/mm 2 for average result of group 1 and for 18 cubes. The compressive strength of M30 grade of concrete at 28 days of compressive strength test result of concrete with novel pumice stone and partial replacement of silica fume and metakaolin by the weight of cement is increased in the percentage of 6.67% over the conventional concrete. It shows better results and performance over conventional concrete.

The research investigates the flexural performance of novel polypropylene monofilament fiber as additive in concrete with conventional concrete. Some of the cement was replaced with novel polypropylene monofilament to strengthen the concrete’s flexural properties. The experiments were divided into two groups. Each group includes 18 different specimens. Pretest power is calculated at 80%. In concrete, cement weight replaced 8% of the polypropylene monofilament. A 100 x 100 x 500 mm prism specimen was subjected to an ASTM standard flexural strength test. The specimens were allowed to cure for 28 days at room temperature before being tested for tensile strength. The independent sample t-test was carried out using SPSS (Statistical Package for the Social Sciences) software version 21. The mean flexural strength of polypropylene monofilament novel fiber-reinforced concrete, with an 8% replacement, was 14.9611 N/mm 2 , as compared to conventional concrete’s 12.9111 N/mm 2 . An independent sample t-test was used to analyze the results. The novel polypropylene monofilament fiber-reinforced concrete had an 8% standard deviation that was 0.360. A significance value of p = 0.000 (two-tailed, p < 0.05) with a statistically significant difference between the two study groups, was noted. When polypropylene mono-filament novel fiber-reinforced concrete is used in place of conventional concrete, the strength of the concrete’s flexural component significantly increases.
该研究调查了新型聚丙烯单丝纤维作为添加剂在混凝土中与传统混凝土的抗折性能。用新型聚丙烯单丝替代了部分水泥，以增强混凝土的抗弯性能。实验分为两组。每组包括 18 个不同的试样。试验前功率按 80% 计算。在混凝土中，水泥重量取代了 8%的聚丙烯单丝。对 100 x 100 x 500 毫米的棱柱试样进行 ASTM 标准抗折强度测试。试样在室温下固化 28 天后进行拉伸强度测试。使用 SPSS（社会科学统计软件包）软件 21 版进行了独立样本 t 检验。替代率为 8% 的聚丙烯单丝新型纤维增强混凝土的平均抗折强度为 14.9611 牛顿/毫米 2，而传统混凝土的平均抗折强度为 12.9111 牛顿/毫米 2。分析结果采用了独立样本 t 检验。新型聚丙烯单丝纤维增强混凝土的 8%标准偏差为 0.360。两个研究组之间的显著性值为 p = 0.000（双尾检验，p < 0.05），差异具有统计学意义。当使用聚丙烯单丝新型纤维增强混凝土代替传统混凝土时，混凝土抗折部分的强度显著提高。

The main scope of the research about comparing the material removal rate (MRR) on Al-Zn5Mg alloy using TiN covered and uncovered tools through a CNC (Computer numerical controller) machining center. Al-Zn5Mg alloy of 200 mm length and 50 mm diameter was used for this study. The 20 Al-Zn-5Mg alloy samples are considered for novel CNC turning operation with TiN covered tool (experimental group). Another 20 Al-Zn5Mg alloy samples are machined the same way but the tool is changed to an uncovered ceramic tool (control group). The weight of each sample before and after the turning process is calculated via a digital weighing machine with ±0.001 gram accuracy. The system of MRR measuring follows the standard of ASTM with 80% G-power calculations. The evaluated results for this experimental study of MRR on Al-Zn5Mg alloy machined by TiN covered tool and uncovered ceramic tool found 1.598 mm 3 /min and 1.254 mm 3 /min respectively. The test results were statistically analyzed via the SPSS (Statistical Package for the Social Sciences) tool and gave a two-tailed significant value of 0.003 (p < 0.05). There is a significant difference between the two groups considered. The two-tailed significance value obtained is 0.003 (p < 0.05) which is statistically significant. Within the limitations of this present study, the Al-Zn5Mg alloy was turned by TiN covered and uncovered ceramic tools through a CNC (Computed numeric control) machining center. The higher MRR is found in the machining operation with TiN covered tool. The value of MRR is greater than the MRR of uncovered ceramic tools.
研究的主要范围是通过 CNC（计算机数控系统）加工中心，比较使用 TiN 涂层刀具和无涂层刀具加工 Al-Zn5Mg 合金的材料去除率（MRR）。本研究使用了长度为 200 毫米、直径为 50 毫米的 Al-Zn5Mg 合金。20 个 Al-Zn-5Mg 合金样品被视为使用 TiN 涂层刀具进行新型 CNC 车削操作（实验组）。另外 20 个 Al-Zn-5Mg 合金样品以相同方式进行加工，但刀具改为无涂层陶瓷刀具（对照组）。车削前后每个试样的重量均通过数字称重仪计算得出，精度为 ±0.001 克。MRR 测量系统遵循 ASTM 标准，G 功率计算为 80%。此次对使用 TiN 涂层刀具和无涂层陶瓷刀具加工 Al-Zn5Mg 合金的 MRR 进行的实验研究得出的评估结果分别为 1.598 mm 3 /min 和 1.254 mm 3 /min。测试结果通过 SPSS（社会科学统计软件包）工具进行统计分析，得出的双尾显著值为 0.003（P < 0.05）。两组之间存在明显差异。双尾显著值为 0.003（P < 0.05），具有统计学意义。在本研究的限制范围内，Al-Zn5Mg 合金通过 CNC（计算机数控）加工中心用 TiN 涂层和无涂层陶瓷刀具进行车削。在使用 TiN 涂层刀具进行加工时，发现 MRR 较高。其 MRR 值大于未覆盖陶瓷刀具的 MRR 值。

The prime aim of this experimental study is to find the material removal rate (MRR) of CBN (Carbon boron nitride) coated and uncoated insert on Al-Si12Cu alloy via a novel computer numeric controlled (CNC) turning center. Al-Si12Cu alloy of 50 mm diameter and 200 mm length was utilized for this study. The samples (N = 20) are turned by CBN coated insert (experimental group) and the uncoated insert is considered as the control group to machining another 20 samples (N = 20). The weight of Al-Si12Cu alloy on both group samples was measured before and after the turning process via a digital weighing machine followed by MRR was calculated as per ASTM standard with 80% G-power calculation. Based on the experimental test results of MRR for the turned Al-Si12Cu alloy by CBN coated insert showed 2.762 mm 3 /min and 1.781 mm 3 /min were found gives a significant value of 0.001 (p < 0.05). There is a significant difference between the two groups considered. The two-tailed significance value obtained is 0.001 (p < 0.05) which is statistically significant compared to the uncoated insert showing the adequacy of the design matrix and there is a significant difference have been between the two groups. Within the limitations of this experimental study, the Al-Si12Cu alloys were turned via CBN coated insert has played a prominent role in the enhancement of MRR rather than the samples turned by the uncoated insert.
