Epoxy grout and the old concrete interface treatment

Concrete from sand treatment main use: 1, new and old concrete connections: this product is the ideal combination of new and old concrete interface connection agent, often used in the construction joints, beam reinforcement and reconstruction and other projects in the old foundation. 2, concrete sand grass-roots repair processing: the product can be used to repair concrete surface rise sand, ballast-surface, reinforcement, etc. 3, concrete surface protection and moistureproof processing: the product can be used for surface protection of concrete and steel, to prevent deterioration and corrosion. Or used in the moist insulation layer of oily coating, combined with polyurethane soil firmly. 4, naisuanjian corrosion requirement of plaster or brick plate paste construction: this product can be used for has naisuanjian corrosion for a special occasion of plaster and tile is spread engineering, and can be in damp base construction. Technical parameters of test results of the test items inspection results shear bond strength Mpa7d1 technical indicators. 3≥1. 0 14 d1。 8≥1. 5 tensile bond strength Mpa unprocessed d0 7. 7≥0. 4 14 d1。 0≥0. 6 flooding process 0. 7≥0. 5 0 heat treatment. 8≥0. Deal with 0 5 freeze-thaw cycles. 7≥0. 5 construction shows that basic level processing to eliminate loose parts, sweep or water rushed to float on the surface of the ash and allow the concrete base with damp or template on a small amount of release agent does exist, but can not have MingShui or a large number of oil accumulation. Adhesive solution prepared a: b = 1:3 ( Volume ratio) With the glue solution. Note: 1, party a and party b take containers used separately, each ingredient unfavorable and overmuch, adhesive solution increases with the increasing with use. 2 - Out of 3 hours. 2, party a and component b shall not be mixed during storage. 3, if found to have water precipitation, after stir the use does not affect performance. Construction craft, the new and old concrete connection construction 1, mortar configuration: according to the J - 302 mixed adhesive solution: water: cement: yellow sand mixing = 1134 the proportion of mixed. 2, roughcast: at the grass-roots level or the broom with the brush tools such as brush to mixed liquid cement mortar mixture on the base, into a rough surface, hardening after plastering construction can be achieved. 3, reference usage: about 0. 3 kg/square meters. Second, sand concrete on basic level processing: 1, mortar configuration: according to the J - 302 mixed adhesive solution: cement: yellow sand = 11 - 21 - The proportion of 2 mixed stirring. 2, remove the ground already fall off or loose sand lime, J - Mixed adhesive solution diluted 1-302 After 2 times, besmear to brush on the sand at the grass-roots level, maximize the glue liquid penetration into the base. 3, will be configured mixed mortar coating 1 - in the region on sand After 2 times, cement pressure light. 4, shall be carried out in accordance with the normal plastering construction maintenance. 5, reference usage: dosage of every working procedure is about 0. 2 kg/square meters, the repair layer thickness different dosage will have change. Three, the concrete surface protection and moistureproof processing: 1, the mortar configuration: according to the J - 302 mixed adhesive solution: cement: fine = 11 - 21 - The proportion of 2 mixed stirring. 2, the configuration of mixed mortar besmear equably on the base, the first to use a thin bit of mixed mortar, the second and third way to use thick mixed mortar. Each working procedure interval should be more than 4 hours. 3, generally concrete protection must besmear to brush, waterproof and moistureproof processing must besmear two to three. 4, reference usage: dosage of every working procedure is about 0. 2 kg/m2, thickness of different dosage will have change. Four, naisuanjian corrosion requirement of plaster or brick plate paste construction: 1, the mortar configuration: according to the J - 302 mixed adhesive solution: water: cement: yellow sand = 112 - 44 - 6 the proportion of mixture stirring. 2, use the configured mixed mortar in accordance with the normal plaster or shop sticks ceramic tile of the construction methods and requirements for the construction. 3, reference usage: 3 - 4 mm thickness calculation, J - 302 mixed gum liquid dosage is about 0. 5 kg/square meters.
