This product also decreases water penetration into cement particles. It\u2019s important to note that using this powdered retarder is only one factor affecting the setting time of concrete; other variables such as cement type, water-to-cement ratio, and ambient temperature significantly influence the setting duration as well.<\/p>\n<h3><strong>Features Concrete Powder Retarder<\/strong><\/h3>\n<ul>\n<li>Improvement of concrete surface finishability<\/li>\n<li>Delaying the setting time of the concrete<\/li>\n<li>Reduction of cold joints due to delays between pouring stages<\/li>\n<li>Increased long-term strength of concrete<\/li>\n<li>Feasibility of concrete pouring in hot climates<\/li>\n<li>Capability of pouring concrete in windy areas<\/li>\n<li>Extension of concrete workability time<\/li>\n<li>Capability of pouring concrete over long distances from batching to discharge location<\/li>\n<li>Prevention of surface cracking caused by concrete shrinkage<\/li>\n<\/ul>\n<p>More products ; <a href=\"https:\/\/proofab.com\/en\/product-category\/concrete-chemical-additives\/\">Concrete chemical additives<\/a><\/p>\n<h3>Applications<\/h3>\n<ul>\n<li style=\"text-align: justify;\">Used in large and semi-large concrete pours<\/li>\n<li style=\"text-align: justify;\">Suitable for pumping concrete applications<\/li>\n<li style=\"text-align: justify;\">Applied in large-scale projects with high concrete volumes, such as dams, bridges, and massive foundations<\/li>\n<li style=\"text-align: justify;\">Enables transportation and construction of concrete over long distances<\/li>\n<li style=\"text-align: justify;\">Ideal for architectural concrete projects<\/li>\n<li style=\"text-align: justify;\">Used in the production and application of roller-compacted concrete<\/li>\n<li style=\"text-align: justify;\">Produces high-strength, impermeable concrete<\/li>\n<\/ul>\n<h3>Technical specification table<\/h3>\n<table style=\"height: 229px; width: 67.1661%; border-collapse: collapse;\" border=\"2\">\n<tbody>\n<tr style=\"height: 39px;\">\n<td style=\"width: 36.8827%; height: 39px; text-align: center;\"><strong>Appearance<\/strong><\/td>\n<td style=\"width: 38.9439%; height: 39px; text-align: center;\" width=\"246\">Powder<\/td>\n<\/tr>\n<tr style=\"height: 39px;\">\n<td style=\"width: 36.8827%; height: 32px; text-align: center;\"><strong>Color<\/strong><\/td>\n<td style=\"width: 38.9439%; height: 32px; text-align: center;\" width=\"246\">White<\/td>\n<\/tr>\n<tr style=\"height: 37px;\">\n<td style=\"width: 36.8827%; height: 37px; text-align: center;\" width=\"236\"><strong>Specific gravity<\/strong><\/td>\n<td style=\"width: 38.9439%; height: 37px; text-align: center;\" width=\"246\">\u00a01 gr\/cm<sup>3\u00a0<\/sup><\/td>\n<\/tr>\n<tr style=\"height: 35px;\">\n<td style=\"width: 36.8827%; height: 45px; text-align: center;\" width=\"236\"><strong>Standard<\/strong><\/td>\n<td style=\"width: 38.9439%; height: 45px; text-align: center;\" width=\"246\">ASTM C494<\/p>\n<p>ISIRI 2930<\/p>\n<p>EN 934 &#8211; 2<\/td>\n<\/tr>\n<tr style=\"height: 35px;\">\n<td style=\"width: 36.8827%; height: 35px; text-align: center;\" width=\"236\"><strong>PH<\/strong><\/td>\n<td style=\"width: 38.9439%; height: 35px; text-align: center;\" width=\"246\">8<\/td>\n<\/tr>\n<tr style=\"height: 41px;\">\n<td style=\"width: 36.8827%; height: 41px; text-align: center;\" width=\"236\"><strong>Chlorine ion<\/strong><\/td>\n<td style=\"width: 38.9439%; height: 41px; text-align: center;\" width=\"246\">Doesn\u2019t have<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<h3><strong>How to Use<\/strong><\/h3>\n<p style=\"text-align: justify;\">The required amount of powdered retarder is calculated based on the concrete mix ratio, then diluted with twice the volume of mixing water.
