富斯樂 Fosroc Renderoc LA55 / 25KG

Fosroc® Renderoc® LA55 是一種高性能、流動性好、低鹼性的微混凝土修復砂漿，符合 EN 1504-3 Class R4 標準。僅需在現場添加清水即可使用，適用於厚度超過 50 毫米的大體積修復。

主要特點

• 高兼容性: 與混凝土壓縮強度 30 - 60MPa 兼容
• 雙重膨脹系統: 控制塑性和長期乾燥收縮
• 低鹼含量: 降低鹼-矽反應風險
• 優異的粘合性: 與混凝土基材粘結強度高
• 低滲透性: 提供優異的二氧化碳和氯化物保護
• 流動性好: 適合在受限位置進行泵送或澆注
• 自密實性: 無需振動，消除蜂窩狀結構
• 適合電化學修復: 使用 Galvashield 陰極保護系統

典型用途

適用於大體積的結構性混凝土修復，尤其是手工或抹刀應用困難的小範圍修復。適合需要優異氯化物和二氧化碳抵抗力的場合。

Fosroc® Renderoc® LA55 is a high-performance, free-flowing, low-alkali micro-concrete repair mortar that conforms to EN 1504-3 Class R4. It requires only the addition of clean water on-site, suitable for large volume repairs over 50mm thickness.

Key Features

• High Compatibility: Compatible with concrete compressive strength 30 - 60MPa
• Dual Expansion System: Controls plastic and long-term drying shrinkage
• Low Alkali Content: Reduces alkali-silica reaction risk
• Excellent Bond: High bond strength to concrete substrates
• Low Permeability: Excellent protection against CO2 and chlorides
• Good Flowability: Ideal for pumping or pouring into restricted areas
• Self-Compacting: Eliminates honeycombing without vibration
• Suitable for Electrochemical Repairs: Compatible with Galvashield cathodic protection systems

Typical Uses

Ideal for large structural concrete repairs and areas difficult to access with hand or trowel-applied mortars. Suitable for environments requiring excellent chloride and CO2 resistance.
