The present of openings in brick walls can have an effect on the load capacity and cracking regime after construction under working load. So, there is a need for strengthening brick walls with openings during construction. In the present study, a total of five brick wall specimens having a wall dimensions (85*65) cm and thickness (10) cm with square opening (25*25) cm were tested. The brick wall specimens were divided into two groups as flow.Group one consisted of one brick wall with R.C lintel 35 cm length as a control wall. Group two consisted of four strengthened brick wall specimens by fixed strip of steel wire mesh covered with cement mortar around opening on both sides of wall. With strip wide (5,10,15,20 cm). All brick wall specimens were tested under static loads in regular increments from zero up to the cracking load then failure load. In addition, wall deformations have been measured by LVDT. The obtained test results show that fixing strip of steel wire mesh covered with cement mortar around opening on both sides of wall with strip wide 5 cm gives an increase in the load carrying capacity up to 135 % from the control ultimate capacity. However, fixing strip of steel wire mesh covered with cement mortar around opening on both sides of wall with strip wide 10 cm gives an increase in the load carrying capacity up to 153 % from the control ultimate capacity. In addition, fixing strip of steel wire mesh covered with cement mortar around opening on both sides of wall with strip wide 15 cm gives an increase in the load carrying capacity up to 167 % from the control ultimate capacity. However, fixing strip of steel wire mesh covered with cement mortar around opening on both sides of wall with strip wide 20 cm gives an increase in the load carrying capacity up to 184 % from the control ultimate capacity. The results suggest that Increasing wide of wire mesh strip increases significantly the load carrying capacity of wall. However, ductility has been significantly increased. In addition, it was found that strengthening with this technique is durable, economic and easy to apply.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"12 1","pages":"131-139"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81470115","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}

Combustion can perform perfectly in proportional rasio of fuel and oxygen.Filter air intake of gas turbine GT 13E2 use cylindrical cartridge filter type and it is installed vertically. air intake filter performance reduce rapidly if operated in dirty ambient air. This condition require filter replacement to maintain air mass flowrate that required in combustion. However, displacement cannot be performed while plant under operation. Therefore, the effort to increase life time of filter is necesary. Existing air intake filter in block 1 utilize 900 pieces of Donaldson brand. the specification of filter are 16 inches outside diameter. 34.5 inches height. celulose base with pourusity 52μ. To reduce amount of attached particle in filter surface, installation weather louver is required. In order to increase plant reliability, availability and maintenance time interval of gas turbine, installation of prefilter and wheater louver at intake of compressor have been performed. This effort provide increasing plant reliability, availability and maintenance time interval. Finally, the benefit of this effort increase productivity of electricity and company profit.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"83 1","pages":"19-24"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83984640","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}

Construction industry uses most of the natural resources as it includes production of cement. It is the major contributing factor to the CO2 emissions, causing global warming. An alternate to the OPC has been found out known as Geopolymer concrete. It uses industrial waste material such as fly ash, GGBS, instead of cement thereby decreasing impacts due to cement production. In this study both fly ash and GGBS are utilized in making Geopolymer concrete. Alkaline solution is used that comprises of sodium silicate (114.206 kg/m 3 ) and Sodium hydroxide (57.10 kg/m 3 ) in the ratio of 2.0. Sodium hydroxide of 8 Molarity is used. In present study various percentages of basalt fibers are added to the geopolymer concrete and the compressive, flexural and split tensile strength of the different mixes were compared with the geopolymer concrete without basalt fibers.

The content of rice husk is varied (10, 15 and 20 weight percentages) whereas the fly ash percentage is kept constant at 5 % in epoxy matrix. Composites have been fabricated using hand layup technique using a suitable die developed in house. All the samples have been tested in Universal Testing Machine as per standard for tensile strength and flexural strength. The hardness and water absorption tests were also carried out. It is observed that composite with 10% rice husk is having highest tensile strength of 33 MPa. Similarly the flexure modulus for 10 % rice husk composite was 4881 MPa. The impact strength of composite with 20 % rice husk was highest. The hardness test showed that composite of 20% rice husk was highest. The water absorption test reveals that composite with 10 % rice husk is the best. It is recommended that composite with 10% rice husk and 5 % fly ash with epoxy matrix will be suitable for structural applications. The composite with 15 or 20 % rice husk may not be used for such purposes. Composite with 15 and 20 % rice husk may be used for making parts of automobiles. But these will not be suitable to work in moist environment. However composite with 10 % rice husk will be suitable for structural applications like packaging, interior decorations, body of washing machines and domestic appliances etc.","PeriodicalId":14565,"journal":{"name":"IOSR Journal of Mechanical and Civil Engineering","volume":"11 1","pages":"91-99"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81649332","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}

Thus, Geopolymer concrete is considered to be the new material that does not require the presence of Portland cement as a binder. Instead, the source of the materials like Silica Fume that are rich in Silicon is activated by alkaline liquids in order to produce the binder. Hence, the resultant concrete will be free from Portland cement.
