Tests performed according to ASTM standard by B.U.E.T. M.I.S.T. & BETON (USA)

According to the ASTM C1202 rating, concrete without admixture was of category “ High Permeability “ even at 90 days of age. But MM -500 mixed concrete just reached the “ Medium Permeability” range at the age of 28 days and the trend shows the chloride permeability is decreasing. ( B.U.E.T & BETON )

>Concrete is made of locally sourced materials to achieve different properties like strength, workability and durability.( Both in USA & overseas). Results of testing will always vary based on the unique mix design. Testing listed is over a control and is a compilation of different tests in which MM-500 is best in class. MMCL highly recommends consulting the technical team for extensive support with all design specifications to the clients requirements to achieve the ultimate result and success of the product usage whether in field tests or lab tests to the final site performance.

>MMCL does not recommend eliminating standard shrinkage control joints. Follow ACI guidelines and MM-500 literature for waterproofing joints.

>Do not assume strength increase will occur rapidly but due to the effectiveness and chemical reaction within the curing process of MM-500, while the plastic state holds the properties initially for best results: the ultimate hardened state will suffice the required strength eventually.

Applications

A pre-pour meeting and consultation with the general contractor, concrete supplier, ready-mix company, finisher, material testing engineers or laboratory technicians are strongly recommended. Treat construction joints, dosage and mixing in accordance to recommendations & instructions. Dose MM-500 up to a maximum 400ml to 110 lbs of cement in consultation with an authorized MMCL representative. Trial batches are required to determine actual plastic properties.

When mixing 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, 24 revolutions recommended.

Ready Mix / Batching Plants – Normal procedures as any other admixture during the mixing at the plant. Consulting MMCL Technical team for accuracy of usage and dosage is highly recommended.

Place and finish concrete in accordance with ACI guidelines. Proper placement and curing are essential to achieve the performance and benefits of MM-500. 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.

To achieve monolithic bonding of blocks between new and old joints of concrete

  • 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.
  • Pressure-wash the joint key thoroughly if needed.
  • Thoroughly brush on MM-500 grouting to the surface.
  • Pour new concrete on and properly vibrate to achieve proper compaction.

Misc Recommendations

  • 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.
  • To achieve stronger bonding and leak proof the concrete, it is recommended to follow the construction joint drawing as per fig: 1, 2 & 3 as shown in the swimming pool applications.
  • Before using MM-500 Cement Grout, please thoroughly clean the surface with water pressure or with a steel brush.
  • 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 stoppers or any form of liquid felts at the joints.
  • Plastering & Stucco : Waterproofing & Damp proofing can be achieved for new, pre existing walls or repair works. In the case of old repair , simply sizzle the old mortar plaster and recast a new layer plaster with MM-500. The dosage would be 400ml for 110 Lbs of cement. Thickness minimum 12mm to maximum 18 mm. Recasting a new layer of concrete over old floors or walls is possible as well. Please consult MMCL's technical team’s recommendation to follow precise methods.
The Plaster and Stucco details are given below.

** The Plaster and Stucco thickness should be 12 mm. to 18 mm.

** Mix design ratio of mortar for Plaster & Stucco should be

1:4 (Cement : Sand)

A. Exterior plaster = 400 ml. per 50 kgs. Cement.

B. Interior plaster = 250 ml. per 50 kgs. cement.

2. STUCCO : MM-500 is suitable for Stucco since MM-500 increases mortar smoothness and flexibility thus helping a mason to allow texture of stucco quickly. MM-500 creates a membrane which helps the Stucco waterproof.

Dosage of MM-500:

A. Exterior Stucco = 400 ml. per 50 kgs. cement.

B. Interior Stucco = 250 ml. per 50 kgs. cement.
