Extension of TD-DSL cement self-leveling cement

I. Introduction Extension of TD-DSL-type self-leveling cement is a special cement, fine aggregate, European professional auxiliaries and additives and other components, and the slurry is mixed with water formed a strong self-leveling; for elastic flooring, wood flooring, carpets and other grass-roots leveling, pre-leveling epoxy floor, and old cement mortar or concrete floor renovation. For indoor and dry ground. 0.5-10mm thickness of the coating in the Second, the technical data mixing ratio: 25kg powder (bag) of about 6-6.5 liters of water (depending on construction temperature) consumption: about 1.5kg / m / mm can construction time of 20 minutes Pedestrian required time: about 5 hours to shop floor time required for about 24 hours at room temperature more than 20 degrees data are only applicable Third, the technical indicators (implementation of the standard: JC / T985-2005) Model: TD-DSL project performance indicators flow degree / mm, the initial fluidity fluidity ≥145 ≥160 20min tensile bond strength / MPa ≥1.3 wear / g ≤0.40 dimensional change / impact resistance of 0.04% from the floor without cracking or 24h compressive strength / MPa ≥15 24h flexural strength / MPa ≥5 compressive strength level grade C16 C20 C25 C30 C35 C40 28 d compressive strength / MPa ≥16 ≥20 ≥25 ≥30 ≥35 ≥40 flexural strength grade strength grade F4 F6 F7 F10 28 d flexural strength / MP ≥4.2 ≥6.0 ≥7.5 ≥10.5 IV Features 1, large liquidity, automatic fine leveling the ground. 2, fast-setting and early strength, improve construction efficiency. 3, low consistency, easy construction. 4, for floor heating. 5, to improve the strength of the lower layer, to prevent cracking. Fifth, the grass-roots preparation 1, the base surface must be dry, solid, load-bearing, clean, no cracks, no adverse residual adhesive objects. Especially the grassroots deficiencies: projections, dents, cracks, grease, dust, etc. must be comprehensively addressed and repaired. Grinding, polishing or shot peening according to grassroots. Then dust with a vacuum cleaner. 2, good tensile strength and compressive strength of concrete. 3. Check the base surface roughness and moisture content, moisture content "4% (CM method): a high moisture content of the grass-roots needs Extension of waterproof material handling use. Especially for new concrete or mortar bed ground floor grassroots recommended moisture content must be examined. 4. Extension of the multi-functional interface agent use after the state required to reach a tack, and no self-leveling fluid before laying. Six construction 1, primer has been absorbed grassroots level, and up to surface dry state (2-6 hours after the primer construction), construction began self-leveling. 2, by adding 6-6.5 liters of water (focus intensity) or 6.5-7 liters of water (emphasis Coverage) in a container, then slowly add a 25 kg bag of TD-DSL1 self-leveling, with a mixer and stir until evenly without group slurry, let aging for about two minutes, stirring once again short, the slurry mixture poured, spread evenly, with a special tooth mouth Scraping blade to control the thickness. Just the coated mixture to prevent direct sun off by strong winds. Inadequate ventilation or hypothermia had a significant effect on the drying time longer. 3, in the initial setting before self-leveling, with foaming rollers roll bar mixed into the ground to exclude air. 4. Laying interval within 10-15 minutes as well, so that phase boundary formation. 5, such as the construction of a multi-layer self-leveling needs to lay in between each layer of multi-function interface needed extension agent primer (dried for 24 hours after the previous one), to ensure construction quality. 6, laying in the grass-roots non-absorbent tiles such as self-leveling time, should be laid at least 2 mm. Seven, to protect the product contains cement, a strong alkaline reaction with water, avoid contact with skin and eyes, after inadvertent contact with the skin or eyes, immediately rinse well with water. When fully cured no harm to health and ecology. Eight Note 1, the goods in the transport, storage should be strictly rain and moisture. Construction temperature not lower than 5 ℃. 2. Do not Tuoda brand and other brands of self-leveling, self-leveling mix. 3. Please do not use this product for long wet grass or outdoors.
