This system has been developed specifically as adhesive injection resin for anchoring cable bolts or applications in combination with the DYWI Drill Hollow Bar System or GRP hollow bars. The easy working principle, a 1:1 parts by volume mixing ratio, and extensive underground field testing characterize this injection resin and provide ideal prerequisites to fulfill requirements for application in underground mining. Additionally, the non-foaming DYWI Inject SILO 8044 can be used for injection works in foundation engineering as well as for filling boreholes or other small cavities. 3

DYWI Inject SILO 8044 Silicate Injection Resin for Anchors and Rock Bolts Installation Procedure Cable bolts Drilling of the borehole According to given specifications with regards to diameter and length Insertion of the cable bolt into the borehole With end holding device Attached grout (or breather) tube Default bulbed version Sealing of the borehole collar Spray foam or borehole plug Resin injection Option 1: top down via the injection tube - connection of the injection tube to the static mixer via a quick coupling (Option 2: bottom up using a short injection tube mounted at the borehole collar - air and resin outflow via the breather tube) Tensioning Fast curing time allows full cable tensioning within less than 30 minutes after installation DYWI Drill Hollow Bar System or GRP hollow bars type CH or CR Self-Drilling installation or insertion into a pre-drilled borehole Optional use of an end holding device Sealing of the borehole collar Spray foam or borehole plug Resin injection Resin flow upwards through the hollow bar, bottom down injection Tensioning Fast curing time allows tensioning within less than 30 minutes after installation Cable Bolt DYWI Drill Hollow Bar Bolt GRP Hollow Bar Characteristics Reaction data 1) Liquid limit Solid Compressive strength 2) Tensile strength 2) Bending tensile strength 2) Shore D after 3 hours Shore D after 24 hours Unit [s] [s] [N/mm 2 ] / [psi] [N/mm 2 ] / [psi] [N/mm 2 ] / [psi] [Shore] [Shore] 20 C / 68 F 60 150 app. 60 / 870 app. 10 / 145 app. 20 / 290 > 60 > 65 1) The indicated values are characeristical values determined under laboratory conditions and may therefore deviate on-site. Actual bond strength development depends on the anchor or rock bolt used, as well as rock conditions and the installation procedure, and must be determined in-situ 2) After 3 days 6
Cleaning and Disposal Provided work interruptions are short, the mixing unit can be rinsed using component A. In case of longer interruptions, rinse - respectively clean - the hoses and pistons of the A side thoroughly with water. Analogously, the B side is rinsed - respectively cleaned - using cleaning agent DYWI Inject Clean 8081. If pumps are not used over a longer period of time, the complete system should be filled with the preservative DYWI Inject Clean P 8086 for injection pumps after cleaning. As cured material can only be removed mechanically, both pump and accessories have to be cleaned immediately after completion of the injection works. For instructions regarding residual material and empty containers, refer to the safety data sheets and a separate DSI leaflet on disposal instructions. Health and Safety When handling DYWI Inject products, EG No. 1907/2006 safety data sheets must be accessible to everyone responsible for material handling, health, and safety. Protective clothing, protective gloves, and face protection/safety glasses must be worn at all times when handling materials, cleaning equipment, and disposing of materials. Where appropriate, protect skin using a protection lotion. In case of skin contact, clean immediately with water and soap. If the product splashes into your eye, immediately rinse with water and seek medical advice. Make sure to present the product safety data sheet during medical assistance. 7
