AC-II water base acrylate grout is developed by Beijing Langwei Times Technology & Science Co., Ltd thanks to toxicity and polluting environment of acrylamide grouting material.water base acrylate grout advantages:1.Non-toxic: All raw material,Website:http://www.lwconchem.com, grout, gel are non-toxic by introduce of new cross-linking agent Instead of methylenebisacrylamide in grout.2.Envirmental friendly: There is antagonistic agent in the grout lead to a better and safer utilization.3.Easy grouting: low viscosity, sound permeability make it easy to fill tiny crack with low pressure4.Economical cost, asy operation, adjustable gel time,-----,A+B components,-----5.High penetration resistance of gel.6.High pressure resistance of gel.7.Water Swelling: good sealing and repetitious swell in dry and wet.8.Durability: gel chemical constitution is stable.Appropriate application:1.Waterproofing of mine tunnel, channel, tunnel, culvert2.Seepage control in concrete3.Infiltration control in sewer networks4.Curtain grouting of dam foundation rock cracks5.Curtain grouting of dam foundation gravel6.Soil stabilization7.Jet concrete constructionComponent of product:Acrylate grout consists of A solution and B: solution A Component: Acrylate solution, accelerator and etc. B component: initiator, regulatorRetarder (use it when you need prolong the Gel time) Applied methodAC-Ⅱ grouting solution is designed according to A solution and B solution equivalent volume mix. After A、 B solutions mix, the gel time is 3~5 minutes in the normal temperature. If you wanted to prolong gel time, the grouting solutions had prepared retarder（red powder）,put retarder into water and become solution of 10%, pouring into B solution, adding quantity is 0.1%~3%（solution of retarder）of grout (by work site small sample test determination). If you wanted to shorten gel time, please to contact us. Ac grout Affect AC-Ⅱ grouting solution has been applied in the subway and hydraulic power project, have taken excellent application effect.Main technical parameterItemⅠTypeⅡTypeTesting methodsStandard of nationalconstructionmaterial tradeAppearanceLight yellow liquidEyeballingHomogeneousliquid of non-soilgrainGroutPercent solids15~1620~21GB/T8077-2000No required（%）Density1.06~1.071.08~1.09GB4472-84±0.05Viscosity＜10＜10GB10247-1988≤10（mPa.s）CircularviscosimeterpH Value7~97~9Acidimeter or pH test6.0~9.0paperToxicityNo-toxicityNationalRequired no-environmentaltoxicityprotection generalwhen use tobureau (2004) testingdrinking water ormethod of chemicalirrigation projectGel timecontrollableBulletin practicalvalueAppearanceSemi-transparent elastic bodyEyeballingNo requiredNCS of grouted＞200＞400ASTM D4219-08Respectivelysand(wet)Gel（kPa）≥200,400Permeability＜1.0×10-6＜1.0×10-7GB/T50123-1999Respectively ＜coefficient1.0×10-6,1.0×10-7（cm/s）Anti-extrude＞300＞600Respectivelyspecific value≥300,600Swelling rate＞30＞30GB/T 18173.3—2002≥30AppendiAxPackageGrout: net weight 40 kg/group, there intoⅠtype: A solution 21.1kg/barrel; B solution 18.9kg/barrel Ⅱtype: A solution 21.5kg/barrel; B solution 18.5kg/barrelRetarder: 5g/bag, 100g/bagStorageSeal keep in the shady, cool and keep away from light, storage temperature between 5℃ to 30℃. Guarantee period: 6 months in the condition of keep seal.PrecautionsAccording to the general chemical grouting requirements, Workers should wear latex gloves, goggles, wear work clothes.Skin, eyes once contact grout, flush 15 minutes with clean water immediately. If swallowed, please go to doctors immediately.
