APPLICATION FOR SWIMMING POOL
Dosage of MM-500 for Swimming Pool
Use 300 ml of MM-500 for every 50 kg of cement for all components of swimming pool: bottom slab, walls, and drains.
Water Cement Ratio for Swimming Pool
Recommended water cement ratio:
- A. Use 40% of water for washed or wet aggregates/(SSD Condition)
- B. Use 50% to 55% of water for dry aggregates.
Mixing
When using MM-500:
Mortar mixing machine – Dilute MM-500 in water for the batch, mix with cement & aggregates. For proper inclusion, 24 revolutions recommended.
Ready Mix Truck – Add MM-500 directly into the truck at site. For proper inclusion, 24 revolutions recommended.
Water Proofing Cement Grout for Swimming Pool Joints
To achieve monolithic bonding of blocks between new and old joints of concrete:
- A. Make cement grout by mixing 12.25 kgs of cement, 12.5 liters of water, then add 1 liter / 33.80oz of MM-500.
- B. Pressure-wash the joint key thoroughly if needed.
- C. Thoroughly brush on MM-500 grouting to the surface.
- D. Pour new concrete on and properly vibrate to achieve proper compaction.
Recommendations for Swimming Pool
- A. To achieve leak proof for high performance concrete (HPC), it is suggested to use strong formwork. This will enable proper compaction as extra vibration can be applied.
- B. To achieve stronger bonding and leak proof the concrete, it is recommended to follow the construction joint drawing as per fig: 1, 2 & 3.
- C. Before using MM-500 Cement Grout please thoroughly clean the surface with water pressure or with a steel brush.
- D. After using MM-500 with the cement grout it is suggested to apply proper vibration to compact the concrete to get high performance concrete (HPC). Excessive vibration will not cause segregation; thus, it will not be required to use PVC water stopper at the joint of the swimming pool.
Curing
Curing influences the overall quality of the concrete structure; thus, proper curing techniques are important to prevent the concrete from shrinking, drying, and cracking especially at the surface. Other than standard procedures no other special curing methods are required. MM-500 helps the concrete to hold the water for self-curing.
