With a density nearly twice that of microsilica powder, it provides better dispersion and usability in concrete applications.<\/p>\n<p style=\"text-align: justify;\">Designed for high-performance, waterproof, and impermeable concrete, microsilica slurry enhances compressive, tensile, and flexural strength. It contains approximately <strong>45-60% silica fume<\/strong>, a higher percentage than typical microsilica gels, making it a superior choice for concrete improvement. This product increases concrete density, reduces permeability, and results in a homogeneous and cohesive mix.<\/p>\n<p style=\"text-align: justify;\">Essentially, this product is a <strong>water-based dispersion of microsilica particles<\/strong>. When mixed with water, it forms a slurry that can be transported in liquid-storage tank trailers. It <strong>replaces a portion of the water typically added to the concrete mix<\/strong>, enhancing its physical and mechanical properties such as strength and durability.<\/p>\n<p>&nbsp;<\/p>\n<h3><strong>Mechanism of Action<\/strong><\/h3>\n<p style=\"text-align: justify;\">Microsilica slurry contains <strong>highly pozzolanic silica fume<\/strong>, which can partially <strong>replace cement<\/strong> due to its similar functionality. When combined with water and calcium hydroxide, it undergoes a reaction forming <strong>calcium silicate hydrate (C-S-H)<\/strong>, which significantly contributes to concrete hardening and strength development.<\/p>\n<p>This <strong>pozzolanic reaction<\/strong> improves:<\/p>\n<ul>\n<li><strong>Impermeability<\/strong>, preventing moisture ingress<\/li>\n<li><strong>Mechanical strength<\/strong>, enhancing durability and resistance to abrasion<\/li>\n<li><strong>Rheological properties<\/strong>, ensuring better workability in fresh concrete<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><strong>Key Benefits and Effects<\/strong><\/h3>\n<ul>\n<li>Increases <strong>compressive, tensile, and flexural strength<\/strong><\/li>\n<li>Enhances <strong>alkaline resistance<\/strong> of concrete<\/li>\n<li>Improves <strong>durability in freeze-thaw cycles<\/strong><\/li>\n<li>Reduces <strong>cement consumption by approximately 20%<\/strong><\/li>\n<li>Suitable for <strong>exposed concrete surfaces<\/strong><\/li>\n<li>Lowers <strong>water-to-cement ratio<\/strong><\/li>\n<li>Enhances <strong>concrete density and impermeability<\/strong><\/li>\n<li>Increases <strong>abrasion resistance<\/strong><\/li>\n<li>Improves <strong>pumpability and reduces equipment wear<\/strong><\/li>\n<li>Higher density compared to microsilica powder<\/li>\n<li><strong>Easier and more cost-effective<\/strong> to transport and store than powder<\/li>\n<li>Prevents <strong>bleeding and segregation<\/strong> in fresh concrete<\/li>\n<li>Can substitute <strong>Type II cement with Type V cement<\/strong><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><strong>Applications<\/strong><\/h3>\n<ul>\n<li>High-modulus concrete structures<\/li>\n<li><strong>Cavitation-resistant<\/strong> concrete structures<\/li>\n<li>Military and <strong>radiation-shielding<\/strong> structures<\/li>\n<li>Concrete for <strong>aggressive and acidic environments<\/strong><\/li>\n<li><strong>Freeze-thaw cycle resistant<\/strong> concrete<\/li>\n<li><strong>Waterproof structures<\/strong>, such as tanks and tunnels<\/li>\n<li><strong>Colored concrete flooring and pavements<\/strong><\/li>\n<li>Durable concrete for <strong>coastal and marine environments<\/strong><\/li>\n<li><strong>Hospital radiation-resistant<\/strong> concrete<\/li>\n<li>High-traffic areas like <strong>parking decks<\/strong> (abrasion-resistant)<\/li>\n<li>Thin-section concrete elements<\/li>\n<li><strong>Mass concrete structures<\/strong> with dense reinforcement<\/li>\n<li>Water tunnels and <strong>low-friction surface canals<\/strong><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3><strong>Physical &amp; Chemical Properties<\/strong><\/h3>\n<table>\n<thead>\n<tr>\n<td><strong>Property<\/strong><\/td>\n<td><strong>Specification<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>State<\/strong><\/td>\n<td>Suspension<\/td>\n<\/tr>\n<tr>\n<td><strong>Color<\/strong><\/td>\n<td>Gray<\/td>\n<\/tr>\n<tr>\n<td><strong>Specific Gravity<\/strong><\/td>\n<td>1.30 \u2013 1.35 g\/cm\u00b3<\/td>\n<\/tr>\n<tr>\n<td><strong>Chloride Ion Content<\/strong><\/td>\n<td>Within standard limits<\/td>\n<\/tr>\n<tr>\n<td><strong>pH<\/strong><\/td>\n<td>~8<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<h3><strong>Dosage<\/strong><\/h3>\n<p style=\"text-align: justify;\">The <strong>recommended dosage<\/strong> of microsilica slurry depends on precise <strong>laboratory testing<\/strong>, raw materials, and environmental conditions.
