The constituents of concrete are coarse aggregate, fine aggregate, coarse aggregate and water. Concrete plays a major role in the construction industry and a large quantum of concrete is being utilized. River sand, which isone of the constituent used in the production of conventional concrete, has become expensive and also a scarce material. In view of this,the utilization of demolished aggregate which isa waste material has been accepted as building material in many countries for the past three decades. The demand of natural sand in the construction industry has increased a lot resulting in the reduction of sources and an increase in price. Thus an increased need to identify a suitable alternative material from industrial waste in place of river sand, that is eco-friendly and inexpensive construction debris i.e fresh concrete being extensively used as an alternative to the sand in the production of concrete. There is an increase in need to find new alternative materials to replace river sand so that excess river erosion is prevented and high strength concrete is obtained at lower cost. One such material is building construction debris: a by-product obtained during construction and demolition waste. An experimental investigation is carried out on M 25 concrete containing debris during construction in the different range of 20%, 30% & 40% by weight of sand. Material was produced, tested and compared with conventional concrete in terms of workability and strength. These tests were carried out on standard cube of 150×150×150 mm and beam of 700×150×150 mm for 28 days to determine the mechanical properties of concrete.","PeriodicalId":13853,"journal":{"name":"International Journal of ChemTech Research","volume":"28 1","pages":"47-53"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79285168","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 objectives of this study are: (1) to study the diversity and density of visitor insect populations to the Kepok banana flower, and (2) to identify insects in the Kepok banana flower that act as carriers of R. solanacearum Phylotype IV, and the population density of these bacteria was carried by each insect. Sampling of banana plantations is done based on pusposive sampling method. Insect collection uses a modified insect net, and insect collection uses modified insect nets, and insects were morphologically identified. This bacterial isolation was carried out based on the spread method on NA + TZC media. Inoculation of bacterial isolates was carried out by injection method on the tip of an mature Kepok banana. Density of insects visitors banana flower per tree in South Minahasa and Minahasa regencies are as follows: Oscinella sp. (15.50 and 18.08 individuals), Aphis mellifera (0.50 and 1.58), Chelisoches morio (0.28 and 0.20 individuals, and Dolichoderus sp. (1.44 and 6.21 individuals).

Now days mostly the construction researchers have been trying to improve the quality and reduced dead weight of the structure and enhance its performance. In this current situation there is a demand in natural sand so engineers are using manufactured sand. The aim of our project is to reduce the dead weight of the structure as well increase the strength of the concrete.So we developed light weight aggregate and sand by using waste plastic and glass materials. We developed a concrete by using crushed glass bottles and melted plastic which is considered as light weight concrete. Glass is an ideal material for recycling use of recycled glass helps in energy saving. This indicate that glass can be effectively used as a fine aggregate replacement without substantial change in strength and also we used aluminum metal powder for reducing the member weight by introduced air in concrete. For the innovative and aesthetic purpose we made the concrete to glow using plastic optical fiber which acts as a transmitting agent which also called as translucent concrete in which the optical fiber is inserted in parallel way. We used epoxy to harden the optical fiber (0.75mm) and M20 grade concrete.","PeriodicalId":13853,"journal":{"name":"International Journal of ChemTech Research","volume":"44 1","pages":"240-250"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87883163","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 effluent samples collected from different processing units of the paper mill varied considerably across the discharge streams. The mean values pH, colour, TS, TDS, TSS, turbidity, BOD, COD, and AOX were found in the range of 2.559.8±0.05, 4102802 PCU, 1980.652785.79 ppm, 1650.672470.35 ppm, 315.44 401.35 ppm, 73.22349.37 NTU, 170.32670.42, 705.522000.55 ppm, and 14.9840.82 respectively.
