Suspensions of Silex 931 do not sediment during processing (!), do not shrink during curing, are particularly easy to pump, and set quickly.\n\n Resistant to sulfates and salts,\n\n good substrate adhesion and strength,\n\n no shrinkage after curing,\n\n very good flow properties,\n\n low viscosity while remaining free of sedimentation.\n\nSILEX Suspension 931 fills voids in structures that are to be sealed by injection. Pre-injection with SILEX-931 closes these defects. It prevents the uncontrolled runoff of the injection agent, supports its uniform distribution in the injection plane, and thus creates an important prerequisite for successful sealing.\n\nSILEX-931 is compatible with horizontal barriers based on silicones or silanes (HydroBloc-Si brands), as well as with HydroBloc gels and resins.\n\nMasonry with many voids, dry-stone walls, and similar structures are stabilized and strengthened by grouting with SILEX-931. Especially through the use of CemBond-956, our cement-reactive additive, added to the mixing liquid for SILEX-931, fragile structures can also be reinforced.\n\nThe substrate must be clean, frost-free, and load-bearing. Impurities in voids and drill holes must be removed, e.g., by blowing them out with dry and oil-free compressed air. Dry substrates should always be pre-wetted before applying the material.\n\u003ch4\u003eProcessing\u003c\/h4\u003e\nSilex Suspension 931 is stirred into clean water provided in a container, using a low-speed agitator. To mix a 20 kg bag of S-931, approx. 10 - 11 liters of water are required. 20 kg of Silex 931 yields approx. 16-17 liters of cement grout. Stir until a homogeneous, flowable mass is obtained. The mixed injection mortar must be processed within 60 minutes. Material that has already started to stiffen must not be re-stirred or diluted!\n\nLarge voids can be filled manually by pouring via a funnel or using hand presses. For more extensive work, smaller voids, and for filling wider cracks, we recommend processing with pumps using the low-pressure method. Eccentric screw pumps and compressed-air diaphragm pumps are particularly suitable for this.\n\nDuring pre-injection for subsequently introduced chemical horizontal barriers using the drill-hole method, the holes filled with Silex-931 can be re-drilled for the subsequent injection after approx. 24 hours.\n\u003ch4\u003eProperties\u003c\/h4\u003e\nMaterial base: Special cements, minerals, and\nadditives\n\nBulk density: Approx. 0.9 kg\/dm3\n\nFresh mortar density: Approx. 1.8 kg\/dm3\n\nProcessing time: Approx. 60 minutes\n\nProcessing temp.: +5 °C to +30 °C\n\nFlexural strength: 1 day approx. 2.7 N\/mm², after 7 days approx. 3.5 N\/mm²\n\nCompressive strength: 1 day approx. 10 N\/mm², after 7 days approx. 30 N\/mm²\n\nVolume change: None (DIN 4227, Part 5)\n\nConsumption: Approx. 1.9 kg per liter of void volume\n\nMachine cleaning: With water\n\u003ch2\u003eSystem accessories for Silex Suspension 931 - injection mortar optimized for void filling\u003c\/h2\u003e\nFilling aid for drill holes No. 77\n\nSeal Fix Expansion Mortar 930 for sealing injection holes\n\u003ch4\u003eContent: 25 kg bag\u003c\/h4\u003e","brand":"ARCAN","offers":[{"title":"Default Title","offer_id":62357905539402,"sku":"1085","price":127.74,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1047\/8626\/4394\/files\/ARCAN-Bauchemie-Abdichtung-Mo_CC_88rtelsysteme-Silex-Suspension-931-_E2_80_93-anwendungstechnisch-optimierter-Injektionsmo_CC_88rtel-zur-Hohlraumverfu_CC_88llung.jpg?v=1782831254","url":"https:\/\/shop.arcan.biz\/en\/products\/silex-suspension-931-anwendungstechnisch-optimierter-injektionsmoertel-zur-hohlraumverfuellung-25-kg","provider":"ARCAN GmbH Abdichtungen – Handwerkerstore","version":"1.0","type":"link"}
