In the utilizations of this earth resource, it is used in the preliminary purposes such as the pottery industry and roof tile manufacturing even though it would be much applicable material/agent for the sake advanced uses because of the variations in the physic-chemical characteristics of most of different clay verities foremost of the adsorption. The investigations of the leaching of some metallic elements to water were the aims and objectives of the existing research component prior to the choosing for the water treatment systems. In the existing research there were experimented three different types of clay types available in Sri Lanka. A few of clay samples from each of clay was dissolved in distilled water and prepared a batch of solutions after filtering each of them. The prepared solutions were analyzed using Atomic Absorption Spectroscope (AAS) for Cr, Mn, Mg, Zn and Cs. As the general outcomes of the relevant analysis, there were obtained 0.8883ppm, 7.4808ppm and 2.003ppm of Cr in anthill clay, brick clay and roof tile clay and 1.8640ppm, 3.1952ppm and 1.1408ppm of Mg in anthill clay, brick clay and roof tile clay. Also there were obtained 0.1059ppm, 0.0632ppm and 0.0863ppm of Mn in anthill clay, brick clay and roof tile clay. When comparing of the obtained results with the Sri Lankan drinking water quality norms there was found some non-hazardous conditions as the maximum permissible limits of Chromium (Cr), Magnesium (Mg) and Manganese (Mn) for drinking water are 0.05ppm, 150ppm and 0.5ppm. The long term effects on the human health as results of the long term contaminated/ non-recommended water consumption and accumulation of such elements.","PeriodicalId":372397,"journal":{"name":"Journal of Materials and Polymer Science","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121494665","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 developed adsorbent, ab initio has been characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The operational parameters evaluated on the adsorption efficiency were solution pH, initial metal ions concentration, temperature, adsorbent dosage, and contact time. The adsorption of Pb (II), Zn (II), Cu (II), Hg (II), Cr (II), Co (II) and Cd (II) ions were found to have attained equilibrium positions in 120 min for the concentration range tested, respectively. Two generally applied linearized adsorption isotherm models; Langmuir and Freundlich tested, when compared, revealed that Langmuir isotherm fitted well to the experimental data judging from the higher correlation coefficient values (R2 ) and lower values of the error functions (chi-square (χ2), the sum of square error (ERRSQ/SSE) and the sum of absolute error (EABS)) with monolayer adsorption capacities of 17.66, 21.12, 14.64, 14.98, 16.60, 13.81 and 15.50 mg/g for Pb (II), Zn (II), Cu (II), Hg (II), Cr (II), Co (II) and Cd (II) ions, respectively. Adsorption kinetic models investigated by pseudo-first-order and pseudo-second-order showed the conformity of pseudo-second-order model to the process of adsorption as informed by the higher values R2 and Adj, R2 , maximum log-likelihood and smaller ERRSQ/SSE, χ2, Akaike information criterion (AIC), Bayesian information criterion (BIC), and Hannan-Quinn information criterion (HQIC).

Roads, bridges and tunnel link people together from the past to the present days. The pavement technology evolved through the centuries. The materials varied with time: from an earthy surface, to stones or cubes, from concrete slabs to hot mix polymer modified drainage asphalt. Depending upon the service condition and the atmospheric exposure, two main materials are used: concrete and asphalt. These building materials exhibited a significant mechanical property evolution in the last decades. Nonetheless, durability aspects, sustainability and maintenance costs awakened some discussions on the general performance of white (concrete) and black (bitumen) materials to be used as a pavement. The case studies focus on some main advantages and disadvantages of both cement-based and bituminous systems. They both can exhibit satisfactory general characteristics, such as surface roughness, mechanical strength, work placing velocity, recycling. Nonetheless, light reflection, surface regularity and the durability may be different. Longitudinal, transverse, net and tongue-like cracks, joints, pop-ups, wash-outs, chemical reactions and surface detachments are some of the defects that influence the functionality. These are largely related to the road layer system properties, road geometry, environment and at the end to the material choice.","PeriodicalId":372397,"journal":{"name":"Journal of Materials and Polymer Science","volume":"540 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116249292","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 broadly used types of lime are quick lime CaO (CL90 Q), hydrated lime Ca(OH)2 (CL90 S), hydraulic lime and lime putty. The primary purpose of hydrated lime is to induce alkalinity and use it as filler material to control porosity. Hydrated lime, unlike hydraulic lime, does not exhibit much-cementing properties on mixing with water. Therefore, it requires blending with suitable binders like cement, pozzolans, and bitumen to acquire better binding characteristics. Hydrated lime is widely used in the iron and steel industry as a cheap, sustainable material for converting iron into pig iron and steel and improving the durability of refractories in the blast furnace. The agriculture and food industry also relies heavily on hydrated lime to be used as a purifying flocculating coagulating agent, especially in the sugar industry. The hydrated lime acts as an alkali activator, deodorising and anti-bacterial chemical in treating wastewater/sludge, agricultural fields and environmental protection. The hydrated lime is used to treat wet, marine and cohesive expansive clayey soils as it absorbs moisture and improves engineering properties like compressibility, strength, plasticity, bearing capacity, consistency, sheer strength and shrinkage etc. One of the main usages of hydrated lime in civil engineering applications is in cementbased mortars as a plasticiser. Therefore, the hydrated lime can be recommended for use in diverse industries and multi-purpose roles.","PeriodicalId":372397,"journal":{"name":"Journal of Materials and Polymer Science","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128462256","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}

They transport drinking water to the households, they refresh or warm up the rooms where we are living, they provide the water in case of fire along the sprinkler systems. Pipes are usually made of metals. These latter exhibit a critical behaviour in contact with water during an inappropriate service life or material choice. In water pipe plants, often corrosion takes place from the external surface and leads to the formation of craters and perforation. The presence of residual water within the embedding material is occasionally observed after the placing works. Condensation phenomena during the transportation of cold water within the pipe may emphasize the corrosion phenomena. The humidity is often adsorbed by the thermal insulating material of the pipe, enhancing corrosion. Galvanic coupling between different materials still represents a relevant issue. Furthermore, material chemical inhomogeneities, junctions and variable thin Zinc thickness of the coating layers contribute to the degradation. Internal corrosion features are also seen sporadically. In particular, in the presence of periodical Oxygen enrichments. On the other hand, stray- current and electrical earth systems generally do not represent a problem.\u0000Keywords: plants, metals, water, durability, corrosion","PeriodicalId":372397,"journal":{"name":"Journal of Materials and Polymer Science","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131852379","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}
