Geopolymer Concrete is one of the emerging concretes with zero cement. Zero percent usage and hundred percentage utilization of pozzolanic material as source material increases the interest of researchers towards geopolymer concrete day by day. Also, reduction of emission of Co2 rate in environment by the less usage of cement consumption increase the thirst of utilizing geopolymer concrete towards academicians, environmentalists and researches. In geopolymer concrete the main source material which is highly embedded with huge percentage of silica and alumina is utilized instead cement. Stimulator solution, combined with Na2Si03 and NaOH is used for processing and activating polymerization process. As a result of polymerization process, chain links and bonds of Silicon-Oxygen-Aluminum are formed to stimulate the strength properties of concrete. Steam, oven and ambient temperature curing methods are preferred in this concrete. Nowadays, interest of geopolymer concrete turn over to applications of geopolymer products rather than construction of structural elements. Applications of geopolymer concrete include paver blocks, precast slabs, pipes, bricks, tiles, etc. Construction of paver blocks in geopolymer concrete plays an important role. This paper describes the review of GPC paver blocks for the past two to three decades which will help to update the knowledge of GPC paver blocks in all aspects.","PeriodicalId":135346,"journal":{"name":"Sustainable Materials and Smart Practices","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126436152","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 major proportion of marine soil is clay so it is generally referred as marine clay (MC). The MC is often weak and lacks stability in heavy loads. This research is concerned with the potential of BA (Bottom ash) and QD (Quarry dust) as soil stabilizers based on resistance enhancement. Soil stabilization points to make strides the geotechnical features of the MC. The engineering properties of MC have been built-up, such as grain size distribution, particle density and soil plasticity. The soil sample was blended and compacted with various quantities of the BA and QD i.e. 2.5%, 5%, 7.5%, 10% 12.5% and 15% for compaction and strength test. The dry-weight method was utilized to prepare the samples. A standard Proctor test was run to determine the stabilized floor OMC and MDD. In the interim, the CBR was conducted to obtain the strength of the stabilized soil. Test results indicate that the MDD of the MC has been improved by 0.19 (g/cc) on addition of 10% BA and it has been improved by 0.246 (g/cc) when 10% QD is added when compared with untreated MC. Laboratory analyses of the cyclic plate load test revealed the ultimate load carrying capacity of the treated MC model flexible pavement has been increased by 349.9% at OMC when compared with untreated MC model flexible pavement.","PeriodicalId":135346,"journal":{"name":"Sustainable Materials and Smart Practices","volume":"152 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122985487","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}

Structural Health Monitoring (SHM) establishes a damage detection system to maintain safety in the current structure. Owners and maintenance managers are looking for cost-effective and dependable inspection and monitoring solutions to ensure the safety and reliability of capital-intensive assets. A longer overhaul time is envisaged with today's software technology and design codes. The visualization aims to put advanced technology into practice to provide consumers and the government with value-added services. Meanwhile, the wavelet transforms, a signal processing technique based on a windowing approach using enlarged 'scaled' and shifted wavelets, is being applied in various industries. By bypassing many of the restrictions of the Fourier transform (FT), the wavelet transform has proven to be effective in SHM systems. Structures tend to get damaged in situations such as accidental fire, aggregate contraction, salinity exposure, corrosion due to bacterial influence, physical and material damage. Also, structures tend to lose their tensile strength when exposed to long-term factors such as moisture, heat, rains, storms, etc. Structural Health Management plays a vital role here to monitor the health conditions of structures to prevent any loss. To stand up for this need, it is imminent to provide a safe structure for people to ply through. The proposed methodology shows a clear picture of how to assess any structure condition at any time and gives a clear view of its current stature on whether it is damaged. Hence in this article, the behavior of the structure is assessed using wavelet transformation. The hardware configurations, including the MSP430FR6989 microcontroller with TDC1000-TDC7200EVM, are embedded with the aggregate, making it smart enough to detect the defects through the software interpretation with a signal processing toolbox of MATLAB coding.","PeriodicalId":135346,"journal":{"name":"Sustainable Materials and Smart Practices","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132354234","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}

Conventional concrete has a low tensile strength, constrained ductility and little protection from crack propagation. The inward miniaturized scale of cracks, prompting weak disappointment of concrete. Investigations have been carried out in many countries on various mechanical properties, physical performance and durability of cement-based matrices reinforced with naturally occurring fibers including sisal, coconut, jute, bamboo, and wood fibers. Raised natural mindfulness and an expanding worry with an unnatural weather change have invigorated the search for materials that can supplant traditional engineered fiber. Characteristic fiber, for example, sisal strands show up as one of the great options since they are accessible in sinewy structure and can be separated from plant leaves, stalk, and products of the soil at exceptionally low expenses. In this work, the impact of sisal strands on the quality of cement for M25 evaluation has been examined by shifting the level of filaments in concrete. Fiber substance were shifted by 0.05%, 0.10%, 0.15%, 0.20%, 0.25%, 0.30%, 0.35% and 0.40% by volume of cement. Cubes, Cylinder and Prism were cast to assess the Compressive, Split Tensile and Flexural Strength test. Every one of the samples was tested for a time of 28 days curing. The results of fiber reinforced concrete for 28 days curing with a varied percentage of fiber were studied and it has been found that there is significant strength improvement with addition of sisal fiber in concrete.","PeriodicalId":135346,"journal":{"name":"Sustainable Materials and Smart Practices","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114756185","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 economic and ecological performance of normal concrete can be increased by modulating fine aggregate content with a series of combinations of steel slag which possess different physical and chemical behaviour based on its cooling method, heating processes. Many research shows that magnetic separating of steel slag increases its efficiency towards integrating with clinker by 50% compared to integrating of clinker with non-magnetically separated steel slag. It has proved to be an impressive replacement material in concrete surfaces where high skid resistance is essential. Steel slag produced in various types of furnaces have different characteristic nature, blast furnace slag (BFS) has hydraulic and cement properties when used in water-bound macadam roads and also in flexible and rigid pavements. Issue in steel slag is energy consumed in its production and transportation where it is utilized, if energy consumed in slag grinding/magnetic separation is high when compared to cement calcining and grinding, then it would not be economical in replacement criteria. This study exhibit mechanical properties of concrete with partial replacement of fine aggregate with steel slag in distinct proportions. The optimum amount of replacement in fine aggregate is found to be 20% giving a strength increment of 8% in the compressive strength category. In split tensile and flexural strength criteria strength increment of 7.5% and 40.625% is observed. There are many practical implications of steel slag in the construction industry, road constructions, and clinker substitutes as granulated BF slag, water treatment plants, evidently many researches have proved slag as productive coarse aggregates replacement.","PeriodicalId":135346,"journal":{"name":"Sustainable Materials and Smart Practices","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131582642","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}
