There are two classes of fly ash:<\/p>\n
Class C is a high-calcium variety that\u2019s made up of less than 2% carbon. It can constitute 15% to 40% of cement material.
\nClass F has a carbon content of 5% to 10% and is a low-calcium material. It typically makes up 15% to 25% of cement material.
\nUsing fly ash can reduce CO2 emissions, provide resistance to cold weather, and reduce cracking problems and permeability. It also can be used to create a smooth, sharply detailed surface.[7]<\/p>\n
Fly ash, like Portland cement, is a fine powder that can act like a pigment. Particle colors can be amber, brown, gray, green, olive, red, yellow, or yellow-brown. The resulting color can vary depending on the concentration of the particles, but it\u2019s often a shade of gray.<\/p>\n
Fly ash bricks tend to only come in small sizes, since they become less durable the bigger they get, and are more prone to fractures and cracking at larger sizes.<\/p>\n","protected":false},"excerpt":{"rendered":"
Fly ash is a fine, powdery substance that forms a material similar to Portland cement when mixed with water. (Portland cement is created by mixing limestone and clay or shale that\u2019s been finely ground or burned.) More than half the concrete placed in the United States contains fly ash.[7] Substituting fly ash for cement concrete in road projects, which require a large amount of material, can be a money-saving step.<\/p>\n","protected":false},"featured_media":1081,"comment_status":"open","ping_status":"closed","template":"","meta":{"_surecart_dashboard_logo_width":"180px","_surecart_dashboard_show_logo":true,"_surecart_dashboard_navigation_orders":true,"_surecart_dashboard_navigation_invoices":true,"_surecart_dashboard_navigation_subscriptions":true,"_surecart_dashboard_navigation_downloads":true,"_surecart_dashboard_navigation_billing":true,"_surecart_dashboard_navigation_account":true,"_uag_custom_page_level_css":"","site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set"},"product_brand":[],"product_cat":[23],"product_tag":[21],"class_list":{"0":"post-1080","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-concrete-blocks","7":"product_tag-shop","8":"desktop-align-left","9":"tablet-align-left","10":"mobile-align-left","12":"first","13":"instock","14":"sale","15":"shipping-taxable","16":"purchasable","17":"product-type-simple"},"uagb_featured_image_src":{"full":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash.png",523,437,false],"thumbnail":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash-150x150.png",150,150,true],"medium":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash-300x251.png",300,251,true],"medium_large":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash.png",523,437,false],"large":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash.png",523,437,false],"1536x1536":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash.png",523,437,false],"2048x2048":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash.png",523,437,false],"woocommerce_thumbnail":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash-300x300.png",300,300,true],"woocommerce_single":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash.png",523,437,false],"woocommerce_gallery_thumbnail":["https:\/\/blakerindustries.com\/blakers\/wp-content\/uploads\/2024\/05\/Fly-ash-100x100.png",100,100,true]},"uagb_author_info":{"display_name":"admin","author_link":"https:\/\/blakerindustries.com\/index.php\/author\/"},"uagb_comment_info":0,"uagb_excerpt":"Fly ash is a fine, powdery substance that forms a material similar to Portland cement when mixed with water.
