Permeable crystallization masterbatch is a powdery mixture prepared from Portland cement, silica sand and active chemicals. It is currently the world's most advanced rigid waterproof material. Penetrating crystallization masterbatch has the characteristics of penetrating crystallization, corrosion resistance, increasing concrete density and improving concrete strength. It can grow into dendritic needle-shaped crystals inside the concrete. This kind of crystal becomes an integral part of the concrete and can prevent it from any direction. The resulting penetration achieves the purpose of permanent waterproofing, and is known as "biocement" internationally. Penetration crystallization masterbatch is a powdery rigid waterproof material made from special cement, quartz sand, etc., and infiltrated with a variety of active chemical substances. After interacting with water, the active chemicals contained in the material penetrate into the interior of the concrete through the carrier water, forming water-insoluble crystals in the concrete, blocking the capillary channels, thereby making the concrete dense and waterproof. Product characteristics of permeable crystallization masterbatch: 1. Suitable for construction on wet base surfaces, and can also be constructed under water seepage. 2. It can resist seepage and withstand strong water pressure for a long time. It is an inorganic material that has no aging problem and has the same lifespan as concrete. 3. It has super penetration ability, penetrates and crystallizes inside the concrete, is not easily damaged, and has extraordinary self-healing ability, which can repair cracks less than 0.4mm. 4. Prevent freeze-thaw cycles, inhibit alkali aggregate reaction, prevent chemical corrosion from damaging the concrete structure, protect steel bars but have no destructive expansion effect on concrete. Scope of application: The product is suitable for waterproofing and protection of concrete structures in underground engineering of industrial and civil buildings, subways and culverts, pools, water conservancy and other projects. Edit this paragraph Construction method of cement-based penetrating crystalline waterproof material: 1. Remove debris and dirt on the surface of the structure and look for cracks. Cracks exceeding 2mm should be repaired with cement first. 2. Take a certain amount of the agent and quantify it based on the size of the spraying area. The first spraying is based on 100m2/8kg. Use spray equipment to spray it evenly on the surface of the structure, and wet the surface in large quantities, but do not let it flow and waste a lot. 3. After the first construction is completed, please allow it to dry naturally for 0.5h in summer and 1h on sunny days in winter. During this period, prepare the second spraying agent to prepare for the second spraying. 4. For the second time, spray the original agent directly on the surface of the structure, with a basic standard of 0. 25kg per square meter. 5. After the secondary operation is completed, spray and maintain with clean water after 3 hours in summer and 4 hours in winter.
