As cement is the main ingredient, whose production generates a significant amount of CO2. A small amount of nanoparticles added to concrete can change the nano-structure of cementitious materials, resulting in high durability. This present work explains the effects of using nano-silica material and polypropylene fibres in the traditional concrete mix. The Nano silica contents of 2%, 3%, and 4 % by replacing cement and polypropylene fibre with 0.1%, 0.15%, and 0.2% of the volume of concrete were considered. Various properties of concrete, such as flexural tensile strength, compressive strength, and split tensile strength were determined. Pullout tests (IS 2770 part 1: 1967) were also conducted to study the effect of nano silica and polypropylene fibre on the bond strength of the reinforcement bars and compared them with normal concrete. The tests are carried out at the casting age of 28 days. It is concluded that the use of nano-material and polypropylene fibres has a minute change in their compressive strength. The Split tensile strength and flexural tensile strength get enhanced by a considerable amount. The results of the study showed that the presence of both nano silica and polypropylene fibre in optimal percentages can improve the mechanical properties as well as bond strength of reinforcement bars embedded in concrete.","PeriodicalId":158282,"journal":{"name":"Journal of Ceramics and Concrete Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114697565","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}

When the concrete members are exposed to extreme conditions cracks develop. When a crack opens harmful contaminants may enter the concrete matrix. Water may enter through this crack and result in the corrosion of reinforcement bars. Corrosion of the reinforcement bar also results in the formation of cracks. Compressive strength, flexural strength, split tensile strength and permeability are adversely affected by the formation of cracks. Once damaged these structures need to be repaired. Self-healing concrete is an environmentally friendly and cost-effective method for repairing small cracks. An efficient microbial agent for preparing self-healing concrete is the bacillus species. The sample preparation is done by using Bacillus subtilis. The concentration of bacillus opted for the sample preparation is cells per millilitre. The mechanical properties of bacterial concrete are experimentally evaluated and compared with that of conventional concrete. The tension in concrete is usually overlooked while evaluating the strength of reinforced concrete sections because it makes such a small contribution to member strength. Yet it makes a significant contribution to members’ performance under service loads. In this work, tension stiffening of bacterial concrete is experimentally evaluated on concrete prismatic members made of M20 grade concrete reinforced with 8mm and 12mm diameter bars. The direct tension specimen has a cross-sectional dimension of 60 X 60mm and a length of 600mm. The total length of the steel-reinforced specimens, including the bars, is 900 mm. The tension-stiffening properties of bacterial concrete are compared with that of conventional concrete.","PeriodicalId":158282,"journal":{"name":"Journal of Ceramics and Concrete Sciences","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116052161","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}

The global demand for building materials is steadily growing, yet the supply of natural resources is diminishing. Every day extraction of sand that is naturally occurring in river beds is destroying the natural quality of river bed and this process of extraction is damaging the flow properties of river and the seepage of water to the retention of ground water level is decreasing day by day. When river sand is transported from river bed to the construction site, the overall cost of the fine aggregate increases exponentially due to labour and transportation charges. Alternative materials have been developed as a result of this situation. Fine granite powder is obtained in granite factories in the process of grinding and wedging granite rocks in wanted shapes and size. The waste produced by cutting granite rocks is carried by water and is stored in tanks. The granite dust is left over after the water is drained and disposed of on the land. In the concrete mix, this granite powder behaves like fine aggregate. For M30 mix proportions, the shift of granite powder replaced is 0%, 15%, 20%, 25% and 30%. The cubes are tested for 7-day compression strength. Compared to normal curing, self-curing has a more significant impact on concrete. Besides not affecting hydration and moisture distribution, it also improves the workability of concrete. In this experimental study, we consider PEG 600 containing polyvinyl alcohol as a synthetic polymer. The test results obtained show for 37% improvement in compression strength when compared with normal concrete.","PeriodicalId":158282,"journal":{"name":"Journal of Ceramics and Concrete Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130816752","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}

The influence of polypropylene fiber in mechanical properties like tensile, compressive and flexural strength is explored by performing a comparative analytical study concerning conventional concrete and polypropylene fiber reinforced concrete (PPFRC). The case study was carried out to know the variation in the behavior of concrete due to different aspects such as spalling, and abrasion resistance. By the proper addition of fiber content in the concrete mix it can be predicted that there might be an increase in the physical and mechanical properties of fiber, so simultaneously by varying the polypropylene fiber content from 0.5% - 2% in terms of volume, samples are tested under controlled curing conditions and the optimum polypropylene fiber content is suggested. Fibers are distributed randomly in a concrete mix; possess to increase the energy-absorption capacity of concrete and leads to a decrease in their plastic shrinkage cracks. Further investigations are highly recommended to understand more about the mechanical properties of (FRC) fiber reinforced concrete.","PeriodicalId":158282,"journal":{"name":"Journal of Ceramics and Concrete Sciences","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129795112","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}

Even though the construction industry is rapidly growing noticeably in the form of tools and materials, the cost of construction has reached saturation point along with the deteriorative impact on the environment. This has led to the embrace of natural fibers like coconut fiber, jute fibers, hemp fibers, flax, etc., in reinforcing concrete. Coconut fiber is quite feasible as a tensile-strengthening material in concrete. This is an effective method for the disposal of coconut waste from mattress industries which reduces the waste disposal and decreases the load on existing landfills. Natural fibers are ecologically acceptable and can reduce global carbon quite effectively. Along with coconut fiber, overburdened soil (OB soil) is also used which is left as waste of Mine deposits. A complete replacement of sand in concrete with OB soil is done to reduce the cost of the material as well as to increase the usage of wastes to bring the best version of the material as an outcome. This experimental investigation mainly focuses on analyzing the strength variation of coconut fiber at varying fiber contents and comparing it with conventional concrete. Various strength tests are done at varying percentages (1%, 3%, and 5% by the weight of cement) of coconut fiber.","PeriodicalId":158282,"journal":{"name":"Journal of Ceramics and Concrete Sciences","volume":"630 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123344254","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}
