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.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139321656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":36802,"journal":{"name":"NanoWorld Journal","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139322587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.
