It comprises 25-70 percent granulated slag, 3 percent gypsum,\nand the rest is clinker. Granulated slag is primarily referred to as a\nnon-metallic product that contains over 90 percent glass content. Portland slag\ncement is widely used in marine construction, industrial projects, and concrete\nroad and flyover construction. Quality and testing parameters concerning\nportland cement are specified in the Indian Standard namely IS 455:2015. The\nBureau of Indian Standards (BIS) refers to the said standard to outline\nguidelines on how such products should be manufactured and tested. Also, these\nnorms serve as the checklist for securing BIS registration. Let\u2019s understand\nmore about IS 455:2015 and the procedure concerning BIS certification for\nPortland Slag cement.<\/p>\n\n\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_82_2 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title ez-toc-toggle\" style=\"cursor:pointer\">Page Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 eztoc-toggle-hide-by-default' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/corpbiz.io\/learning\/bis-certification-for-portland-slag-cement\/#Significance_Of_IS_455_2015_and_Its_Role_in_BIS_Certification\" >Significance Of IS 455:2015 and Its Role in BIS Certification<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/corpbiz.io\/learning\/bis-certification-for-portland-slag-cement\/#Tests_to_Qualify_For_BIS_Certification_for_Portland_Slag_Cement\" >Tests to Qualify For BIS Certification for Portland Slag Cement<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/corpbiz.io\/learning\/bis-certification-for-portland-slag-cement\/#Marking_Norms_to_Be_Followed_By_the_Manufacturer\" >Marking Norms to Be Followed By the Manufacturer<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/corpbiz.io\/learning\/bis-certification-for-portland-slag-cement\/#Documents_Needed_For_BIS_Certification_for_Portland_Slang_Cement\" >Documents Needed For BIS Certification for Portland Slang Cement<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/corpbiz.io\/learning\/bis-certification-for-portland-slag-cement\/#How_to_Obtain_BIS_Certification_for_Portland_Slag_Cement\" >How to Obtain BIS Certification for Portland Slag Cement?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/corpbiz.io\/learning\/bis-certification-for-portland-slag-cement\/#Conclusion\" >Conclusion<\/a><\/li><\/ul><\/nav><\/div>\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Significance_Of_IS_455_2015_and_Its_Role_in_BIS_Certification\"><\/span>Significance Of IS 455:2015 and Its Role in BIS Certification<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul><li>IS 455:2015 is an Indian\nStandard that outlines how Portland slag cement should be manufactured, what\nshould be it chemical and physical requirements, and how it should be tested.<\/li><li>Portland slag cement must\ncontain fundamental constituents such as clinker, gypsum, and granulated slag\nin apt proportion.
