| titleOfInvention | ADDITIVES TO CONCRETE AND BUILDING MIXES |
| abstract | 1. Additives for concrete and building mixtures, including various sodium salts, characterized in that the used sodium salts are used absorption solutions of the arsenic-soda method for coke oven gas desulfurization, which are formed after neutralization of the absorption solution with sulfuric acid, filtration from the precipitation of arsenic and sulfur sulfides , neutralize and alkaline compound and have the following characteristics:! - salt content in solution:! Na2S2O3 - 158.8-250.0 g / l! NaSCN - 17.5-90.0 g / l! Na2SO4 - 40.0-86.3 g / l! Na2CO3 - 15.0-51.3 g / l! Na2SO3 - 0.6-23.8 g / l! Na2S - 6.3-38.8 g / l; ! - the total salt content in the solution is 300.0-500 g / l; ! - pH of the solution = 7.0-9.5. ! 2. Additives according to claim 1, characterized in that they additionally contain individual salts that are part of the spent absorption solution of the arsenic-soda soda gas desulfurization method (for example, sodium sulfate, sodium thiosulfate, sodium thiocyanate, sodium carbonate), but obtained the target method, and / or individual salts that are not part of the spent absorption solution of the arsenic-soda method for the desulfurization of coke oven gas, and / or superplasticizers and / or plasticizers and / or setting retarders ementnogo test. ! 3. Additives according to claim 1 or 2, characterized in that they are used as accelerators of setting the cement paste and hardening of concrete and mortar. ! 4. Additives according to claim 1 or 2, characterized in that they are used as anti-frost components for concrete and mortar. ! 5. Additives according to claim 2, characterized in that they are used as plasticizers and superplasticizers for concrete and mortar. ! 6. Additives according to claim 2, excellent |
