APPLICATION FOR SWIMMING POOL
Dosage of MM-500 for Swimming Pool
Use 300 ml / 13.52 oz of MM-500 for every 50 kg / 110 lb 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.
- 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, 6-10 revolutions recommended.
Ready Mix Truck – Add MM-500 directly into the truck at site. For proper inclusion, 6-10 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 / 27lbs of cement, 12.5 liters / 3.30 gallons 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.
