As the name indicates, it is a mixture of Portland clinkers and pozzolana materials, namely fly ash.\u00a0<\/p>\n\n\n\n<p>The strength of these cements comes from calcium hydroxide and fly ash. When water reacts with these two materials, they create a bond that leads to&nbsp; the hydration process and results in enhanced strength of the cement.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages of Portland Pozzolana Cement<\/h3>\n\n\n\n<p>There are certain advantages to PPC, and they are listed below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Workability:<\/strong> PPC has high workability, is easy to handle, and can undergo a variety of easy construction applications.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Less Heat Release:<\/strong> PPC releases less heat compared to other cement during the hydration process. This reduces cracks caused by overheating and protects the overall building structure.&nbsp;<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Endurance:<\/strong> PPC can withstand environmental damage caused by moisture permeation.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Resilient to Chemical Attacks:<\/strong> PPC is not adversely affected by sulphide or chloride attacks, ensuring stability in demanding environments.<\/li>\n<\/ul>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sustainability:<\/strong> PPC is an eco-friendly option and can withhold high-performance benchmarks.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Applications of PPC<\/h3>\n\n\n\n<p>The application of PPC is diverse due to its compatibility and versatility, which play a vital role in infrastructure projects. The applications include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Plastering<\/li>\n\n\n\n<li>Residential buildings<\/li>\n\n\n\n<li>Marine structures<\/li>\n\n\n\n<li>Construction of sewage pipes and dams, and<\/li>\n\n\n\n<li>Masonry work.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Portland Slag Cement (PSC)<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"567\" src=\"https:\/\/wordpress-preprod.bricknbolt.com\/blogs-and-articles\/wp-content\/uploads\/sites\/2\/2024\/08\/ppc-vs-psc-cement-2.webp\" alt=\"Portland Slag Cement (PSC)\" class=\"wp-image-6448\" style=\"width:900px\" srcset=\"https:\/\/wordpress-preprod.bricknbolt.com\/blogs-and-articles\/wp-content\/uploads\/sites\/2\/2024\/08\/ppc-vs-psc-cement-2.webp 1000w, https:\/\/wordpress-preprod.bricknbolt.com\/blogs-and-articles\/wp-content\/uploads\/sites\/2\/2024\/08\/ppc-vs-psc-cement-2-300x170.webp 300w, https:\/\/wordpress-preprod.bricknbolt.com\/blogs-and-articles\/wp-content\/uploads\/sites\/2\/2024\/08\/ppc-vs-psc-cement-2-768x435.webp 768w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" \/><\/figure>\n\n\n\n<p>PSC is a blend of cement consisting of Portland <strong><a href=\"https:\/\/www.bricknbolt.com\/blogs-and-articles\/construction-guide\/what-is-cement-clinker\">cement clinker<\/a><\/strong>, gypsum and blast furnace slag. Slag is essential because it is a non-metallic product that contains more than ninety percent of a mixture of silicates and alumino-silicates of lime.&nbsp;<\/p>\n\n\n\n<p>PSC is made by a blend of 35-70% slag, 25-65% clinker, and 3-5% gypsum.
