Thixotropic, structural, fibre reinforced cement mortar with high intrinsic watertightness, and extraordinary physical and mechanical characteristics: adhesion to concrete, adhesion to steel, compression resistance, flexural strength, abrasion resistance. Perfect for remediation of structural works and articles in degraded concrete and very high performance coatings. Thanks to the very high adhesion to steel and concrete supports, it is also suitable for fixing threaded bars in holes made on concrete or rock conglomerates. Apply with brick trowel and plastering trowel. Rheoplastic, thixotropic, structural, composite cement mortar, based on special cements and selected siliceous aggregates, reinforced with a balanced mixture of READYMESH polypropylene fibres and calcium metasilicate microfibres, added with specific agents and a high content of silica fume. After hardening, it provides very high performance in terms of intrinsic watertightness, resistance to washing and hydrolysing, mechanical strength, abrasion and cavitation, anti-carbonation, chemical-physical stability, resistance to harsh atmospheric agents and to leaching water. It is fibreglass reinforced three-dimensionally, it provides high adherence and adhesion; and dimensionally stable (shrinkage-compensated). The product is mixed with water (approx. 16% of the weight of the bag). Repairs and protective coatings of hydraulic works (pipelines, dams, tunnels etc.), marine structures and artefacts in critical situations: aggressive chemical-physical agents, leaching water, marine atmosphere, etc. For wet spritz beton operations it is advisable to use the Repar Tix HG SB mortar, which maintains the physical and mechanical characteristics of Repar Tix HG, but is specially formulated for the maximum performance of sprayer machines. Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface". An adequate roughening of the surfaces by scarifying, sandblasting etc. is always necessary in order to obtain the maximum adhesion values to the substrate. The optimal values are obtained with high pressure hydro-scarification. Bare the irons undergoing disruptive oxidation or deeply oxidized, removing the rust of the exposed irons (by sandblasting or abrasive brushes). Pour about 2/3 of the mixing water into the mixer, add Repar Tix HG and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 16% of the weight of the bag. The addition of Bond HG to the mixing water (about 0.5 litres per 25 kg bag of product) allows further improvements in terms of adherence, adhesion, watertightness, workability, moldability and deformability. For high coating thicknesses, static, monolithic requirements, etc., performed with Repar Tix HG, appropriate metal reinforcements (mesh, cages, etc.) should be used, anchored to the support with Syntech Profix, GROUT MICROJ, Repar Tix G2, or with the same Repar Tix HG. Approximately 18,5 kg/m² of Repar Tix HG for every centimetre of thickness to be implemented (approximately 1850 kg per cubic metre).
