Planitop HB25 是一款聚合物改性水泥修補砂漿,用於修補垂直或頂部混凝土表面。這種砂漿具備中等機械性能特徵,能在無需模板的情況下應用於厚度相對較大的區域。
主要特點
- 優異的粘附力:與現有混凝土表面具有卓越的粘附性,只需在修補前飽和混凝土表面並使用 Mapefer 處理鋼筋。
- 良好的機械性能:具備設計的抗彎和抗壓強度,彈性模量、熱膨脹係數和滲透係數與中等質量的混凝土相似。
- 易於應用:混合後形成易於塗抹的觸變性砂漿,能在不下垂的情況下應用於垂直和頂部表面,即使是相對較厚的區域。
- 環保配方:不含氯化物,對環境友好。
典型用途
- 混凝土表面修補:修補因鋼筋銹蝕而損壞的混凝土表面和梁底。
- 快速修補:快速修補垂直、水平、頂部的混凝土或砂漿表面。
- 大面積鋼筋保護層重建:重建大面積的鋼筋保護層。
- 表面不規則修補:修補包括暴露的骨料、新舊混凝土之間的接縫、模板混凝土中的孔洞、突出的鋼筋等表面不規則。
Planitop HB25 is a polymer-modified cementitious repair mortar designed for repairing vertical or overhead concrete surfaces. This mortar has medium mechanical performance characteristics and can be applied to substantial thickness without the need for formwork.
Key Features
- Excellent Adhesion: Superior adhesion to existing concrete surfaces provided they are saturated with water and reinforcing bars are treated with Mapefer before application.
- Good Mechanical Performance: Designed flexural and compressive strength, with modulus of elasticity, thermal expansion coefficient, and permeability coefficient similar to that of medium quality concrete.
- Easy Application: Forms an easy-to-apply thixotropic mortar that can be applied without sagging, even on vertical and overhead surfaces, in substantial thickness.
- Eco-Friendly Formula: Free from chlorides, making it environmentally friendly.
Typical Usage
- Concrete Surface Repair: Repair deteriorated concrete surfaces and soffits of beams damaged by rusted reinforcing bars.
- Fast Repairs: Quick repairs to vertical, horizontal, overhead concrete, or mortar surfaces.
- Large Area Reinforcement Cover Reconstruction: Reconstruction of concrete coverings of reinforcing bars over large areas.
- Surface Irregularity Repair: Repair surface irregularities including exposed aggregate, joints between new and old concrete, holes in formwork concrete, protruding steel, etc.
