A Novel Parameter-Light Subspace Clustering Technique Based on Single Linkage Method

Abstract: Subspace clustering is a challenging high-dimensional data mining task. There have been several approaches proposed in the literature to identify clusters in subspaces, however their performance an...

Engineering Comportment of Clays Motleyed with Rice Pericarp Slag (RPS)

Abstract: The waste generated today is no more a waste according to many scientific community, and this waste has been put into many different of engineering application use. For example, the construction industry has plethora of such material which have been generated as waste, and further the progress and use of manufacturing and pastoral wastes, such as fly ash, blast furnace slag, metakaolin, rice pericarp slag (RPS), and bagasse ash (BA), are rapidly receiving attention as reviewed in many literatures [1, 2, 3]. The custom of ashes by the grinding process in cement concrete generally mends the properties of concrete, and the concretes encompassing ground fly ash or RPS are of good quality with condensed porosity and improved immunity to sulphate attack and chloride infiltration [4, 5] as well as great power [6, 7, 8]. Comparing to the fly ash which is the most common pozzolan being used worldwide in soil stabilization [9], the utilization of rice pericarp slag as pozzolanic material is still comparatively low. This tabloid benevolences the upshot of RPS on index and engineering properties of expansive clay. Liquid limit (LL), plastic limit (PL), plasticity index (PI) and free swell index (FSI) and unconfined compressive strength remained determined at capricious quantities of RPS. Unconfined compressive strength of the RPS clay amalgams was determined at their respective OMC and MDD, by piloting standard proctor compaction tests. LL, PI and FSI decreased significantly with increasing RPS content.

Application of Nanoparticles in Construction Industries and Their Toxicity

Abstract: Global development is reflected in the growth of the construction field. To improve the construction related activity and impart the beneficial essence of current technology, nanoparticles are used by the industries at different stages. The size dependent properties of nanoparticles in the construction industry is considered for enhancing material strength, crack recovery, self-cleaning applications, antimicrobial coating, energy conservation and restoration of cultural heritage. Nanoparticles used in the construction industries reach the ecosystem through multiple channels and cause environmental implications such as adverse effects on environmentally relevant microbial species, algae, plants, and entry into the food chain. The exposure to nanoparticles by human beings also causes various health implications such as DNA damage, inflammation and cell death. Therefore, it has become crucial to determine toxicity and assessment of risk during the use of nanoparticles. Their toxicity depends on chemical and physical attributes. Uniform global regulatory policy needs to be framed to assess the toxicity, risk and approval of nanoparticles in the construction industries.

Effect of Bacteria Inoculums on Compressive Strength

Abstract: The use of bio-concrete is increasing in the present day context and researchers are working on strength and durability characteristics of concrete using bacteria species which have shown calcite precipitation. Three different species of bacteria namely P. Fluorescence, B. Pumilis and B. Subliis that have calcite precipitation properties have been investigated in this study. The investigations were carried first on cement mortar (CM) cubes using these three bacteria species suspension of 20%; 40% and 60% having colony forming units P. Fluorescence (108 CFU/ml), B. Pumilis (106 CFU/ml) and B. Subtilis (108 CFU/ml) respectively. The 40% suspension in all the three cases has shown increased compressive strength as compared to 20% and 60%. The compressive strength measured showed increase (CS) of 18%; 12% for P. Fluorescence; B. Subtilis and decrease of 35% with B. Pumilis respectively. B. Subtilis with optimized 40% suspension having CFU 10x108/ml showed 4.32% ; 5.56%; and 3.81% increase in CS of CC cubes with 3 days; 7 days and 28 days respectively and 5.92% overall increase in CS of CC cubes as compared to the 3 days CS of control cube.
