Economic Operation of Cement: A Case of Gautam Buddha Airport Upgrading Component Project

Abstract

The cost of cement is very crucial for the effective construction of any project. The aim of the paperis to assess the economic operation of cement used for Gautam Buddha Airport UpgradingComponent construction projects. The economic operation of cement in terms of their quality,consumption, and cost ensuring the strength requirements by concrete is done. Tests for magnesiaoxide, insoluble residue, setting time, and compressive strength were operated. Compressivestrength test was conducted on cement mortar cubes (1:3) and on concrete cubes developed by thedesign mix at the laboratory at 7 and 28 days. On the basis of the design mix, the cost differenceamong these brands for those sites is evaluated. Purposive sampling technique was applied toconduct the interview of project managers of each site and lab technician of Multi lab. Magnesiaoxide, insoluble buildup, setting time, and compressive quality properties were discovered to bedistinctive as guaranteed by the producer in their concrete endorsements. Furthermore, the resultsof the design mix showed that different quantity of cement is required depending upon the brand forM25 concrete. The average mean of compressive strength of concretes casted at the field of AdminBuilding, International Terminal Building and Crass Fire Rescue Building sites for M25 were28.952 N/mm2, 29.032 N/mm2& 27.924 N/mm2respectively. Based on quality, content, and rate analysis, 53-grade cement is cost effective. So further grading of Ordinary Portland Cement needs to be specified along with strict inspection of cement for assuring quality. The cement produces must be assured to conform to the stated standard
