Ramco Block fix (BFM1) is a thin-joint mortar with high strength attributes for firmly laying AAC blocks. It is a factory mixed mortar constituting Portland cement, graded sand, blended with polymer additives. Even at 3 mm thickness it imparts high strength and water retention properties. As the product is being manufactured in a controlled environment and the output quality is consistent across batches. For best results the blocks should be cleaned using a brush to remove any dust or loose particles. In order to minimize the suction of water wet the blocks prior to using Ramco Block Fix for jointing. Free water on the surface should be allowed to disperse before applying the mortar.
Specification
Portland cement, graded sand, special additives for better water retention, bonding, flowability and workability.
Consumption
Demand of water: 8 – 10 Litres per 40 kg bag.
1 bag of 40 kg covers an area => 120 – 145 sft @ 3 mm thickness under ideal conditions.
Surface preparation
The block should be dry and clean. Ensure that there is no dust or loose particle material on the surface of block.
Mixing
RAMCO Block Fix (BFM1) – contains all ingredients in dry form, only water needs to be added. Mix 8 – 10 liters of clean water with 40kg of dry mortar until a homogeneous smooth mass is reached. Do not mix longer than 5 minutes. Material which has begun to harden or is caking should not be used.
Application
Apply Ramco Block Fix (BFM1) to fix to only AAC block and lay the block within the open time specified. In order to get uniform thickness of the mortar, comb it with a notched trowel before placing the blocks on it. Push AAC blocks into mortar to form uniform vertical joints with minimum gap. For concrete surface joints roughen and apply thin layer to the concrete surface to improve the bonding strength. Point all the horizontal joints when the mortar has set to thumb print hard.
Features and Advantages
Ramco Block Fix (BFM1) is prepared with proprietary technology with the polymers and binders ensuring a high bond strength leading to superior masonry strength and excellent load bearing capacity. Ramco block fix (BFM1) is a recommended mortar for Aerated light weight blocks.
The advantages of Ramco Block Fix over conventional cement mortar are
- Improved adhesion between blocks
- Excellent workability
- Flexible, shock and impact resistant
- Improved compressive and tensile adhesion strength
- Easy to use
- Better value proposition as compared to conventional mortars.
Cost effectiveness
Reduced construction timelines also reduces the direct labour costs. The volume of dry mix mortar is considerably less than traditional mortar giving a distinct cost advantages. A 40 kg bag of Ramco Block Fix (BFM1) covers an area of 110 – 125 SFT for a 3 mm thickness bed. Logistical complexity of the product is reduced as the material is premixed and requires only water addition at site. Mortar thickness of 3mm is sufficient to bind the blocks together. It is self-curing.
Packing/storage and shelf life
The product is available in 40 kg bags. Has a shelf life of 6 months from the date of manufacture, when stored in dry conditions.
Precaution
Ramco Block Fix (BFM1) is non-hazardous, but due to the cementitious nature, it advisable to wear a filter mask, goggles and protective coat. In case of eye contact, wash copiously with water and if irritation persists seek medical treatment.
