Hebei Langfang Dry Mixed Composite Lightweight Aggregate Concrete Manufacturer Sales

Composite lightweight aggregate concrete raw materials include cement, fly ash, granular and inorganic binder materials, free of benzene and other harmful substances, and meet national environmental protection standards. The composite lightweight aggregate concrete cushion can improve the thermal insulation, heat insulation, sound insulation, and load-bearing capacity between floors; it can reduce the roof load; it facilitates the arrangement and installation of ground pipeline. Used as a damp-proof layer, it can also prevent dampness from returning to the floor, keeping the floor dry and preventing deformation, discoloration of various wooden floors, plastic boards, ceramic tiles, and is highly beneficial for damp-proofing and waterproofing of basements, reducing the building load, and lowering construction costs. This product is non-fired, non-steamed, waste recycling, low-carbon energy-saving, and meets the requirements of national development. It follows the standard "Technical Code for Lightweight Aggregate Concrete" JGJ51-2002. Second, performance indicators: Item Performance Indicators Ready-mixed cushioning powder appearance uniformity Composite lightweight aggregate uniform granular dry bulk density (kg/m3) 600-750 Compressive strength MPa ≥1.5 Softening coefficient ≥0.7 Linear shrinkage (%) ≤0.2 Third, construction method: Substrate treatment: Before laying the composite lightweight aggregate
Before laying the underlay concrete, treat the subgrade of the concrete floor, chisel off loose concrete and mortar adhered to the subgrade with a chisel, brush off the cement paste with a wire brush, and then sweep clean with a broom. Determine the elevation and apply horizontal control lines: Measure the underlay elevation from the 100cm horizontal line on the wall, and if possible, mark it on the walls around. Mixing: First, add an appropriate amount of water to the mixer, then add one bag of pre-mixed underlay powder and mix it into a uniform slurry. Next, add one bag of inorganic lightweight aggregate, continue to mix to form a uniform concrete mixture, and it is ready for application. Laying, tamping, or rolling: Spread the mixed composite lightweight aggregate underlay concrete, use a shovel to lay the concrete on the subgrade, level it using the leveling block already made, raising it 3mm above the leveling block. Then, use a flat vibrator to compact and level. If the thickness is thin, you can lightly press with a shovel and a special wooden tamping board as you lay it, and immediately level it with a straight edge, then smooth it with a wood trowel. Complete all operations within 3 hours.
