Additionally, during the hydration process, the evaporation of water creates capillary tubes, which further increases the permeability of the concrete. To reduce this permeability, the use of silica fume or microsilica powder as a suitable additive is recommended. Silica fume particles, which are finer than cement grains, can effectively fill these microscopic spaces. Microsilica powder is a gray-colored powder that contains about 94-96% silicon dioxide (SiO2), and it is produced during the production of ferrosilicon in electric arc furnaces. This powder is added to concrete during production to enhance certain properties. As a result, adding silica fume to concrete compresses the cement paste structure, reduces permeability, and increases the concrete\u2019s strength.<\/p>\n<figure id=\"attachment_1457\" aria-describedby=\"caption-attachment-1457\" style=\"width: 300px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1457\" src=\"https:\/\/proofab.com\/en\/wp-content\/uploads\/2024\/03\/1-34-300x216.jpg\" alt=\"Microsilica Powder\" width=\"300\" height=\"216\" srcset=\"https:\/\/proofab.com\/en\/wp-content\/uploads\/2024\/03\/1-34-300x216.jpg 300w, https:\/\/proofab.com\/en\/wp-content\/uploads\/2024\/03\/1-34-1024x737.jpg 1024w, https:\/\/proofab.com\/en\/wp-content\/uploads\/2024\/03\/1-34-768x553.jpg 768w, https:\/\/proofab.com\/en\/wp-content\/uploads\/2024\/03\/1-34-1536x1105.jpg 1536w, https:\/\/proofab.com\/en\/wp-content\/uploads\/2024\/03\/1-34-2048x1474.jpg 2048w, https:\/\/proofab.com\/en\/wp-content\/uploads\/2024\/03\/1-34-700x504.jpg 700w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-1457\" class=\"wp-caption-text\">Microsilica Powder<\/figcaption><\/figure>\n<h3>Features and benefits Microsilica Powder<\/h3>\n<ul>\n<li style=\"text-align: justify;\">Increases tensile, compressive, and flexural strength of concrete<\/li>\n<li style=\"text-align: justify;\">Enhances resistance to concrete wear<\/li>\n<li style=\"text-align: justify;\">Improves electrical properties of concrete and prevents rebar corrosion<\/li>\n<li style=\"text-align: justify;\">Increases durability and stability of concrete<\/li>\n<li style=\"text-align: justify;\">Reduces cement consumption in concrete mix<\/li>\n<li style=\"text-align: justify;\">Decreases the potential for alkali-aggregate reactions<\/li>\n<li style=\"text-align: justify;\">Protects concrete against chemical attacks<\/li>\n<li style=\"text-align: justify;\">Prevents the occurrence of cancer-related phenomena<\/li>\n<li style=\"text-align: justify;\">Improves workability and facilitates concrete placement<\/li>\n<li style=\"text-align: justify;\">Increases cohesion and reduces permeability of concrete<\/li>\n<li style=\"text-align: justify;\">Enhances concrete mass density<\/li>\n<\/ul>\n<p>More products ;
