What is the formulation of dry mixed mortar?

Dry mixed mortar is a type of construction material that is used to bind together various components such as cement, sand, and other additives. It is commonly used in the construction of walls, floors, and other structures. Dry mixed mortar is a convenient and cost-effective solution for many construction projects.

The formulation of dry mixed mortar is a complex process that involves the selection of the right ingredients, the proper mixing of the components, and the correct application of the mortar. The formulation of dry mixed mortar begins with the selection of the appropriate ingredients. The most common ingredients used in dry mixed mortar are cement, sand, and other additives. The selection of these ingredients depends on the type of project and the desired properties of the mortar.

Formulation of Dry mixed Mortar as bellow:

1.Bonding mortar formulation
42.5 cement: 400kg

Sand: 600kg

emulsion powder: 8-10kg

Cellulose ether (150,000-200,000 CPS): 2kg

If the redispersible emulsion powder is replaced by resin powder, the added amount of 5kg can break the board

2 .Plastering mortar formulation
42.5 cement: 400kg

Sand: 600kg

Latex powder: 10-15kg

HPMC (150,000-200,000 sticks): 2kg

Wood fiber: 2kg

PP staple fiber: 1kg

3. Masonry/Plastering Mortar formulation
42.5 cement: 300kg

Sand: 700kg

HPMC100,000 sticky: 0.2-0.25kg

Add 200g of polymer rubber powder GT-508 to one ton of material to achieve 93% water retention

4. Self-leveling mortar formulation
42.5 cement: 500kg

Sand: 500kg

HPMC (300 stick): 1.5-2kg

Starch ether HPS: 0.5-1kg

HPMC (300 viscosity), low viscosity and high water retention type, ash content less than 5, water retention 95%+

5. Heavy gypsum mortar formulation
Gypsum powder (initial setting 6 minutes): 300kg

Water washing sand: 650kg

Talc powder: 50kg

Gypsum retarder: 0.8kg

HPMC8-100,000 sticky: 1.5kg

Thixotropic lubricant: 0.5kg

The operating time is 50-60 minutes, the water retention rate is 96%, and the national standard water retention rate is 75%

6. High-strength tile grout formulation
42.5 cement: 450kg

Expansion agent: 32kg

Quartz sand 20-60 mesh: 450kg

Washing sand 70-130 mesh: 100kg

Polyxiang acid alkali water agent: 2.5kg

HPMC (low viscosity): 0.5kg

Antifoaming agent: 1kg

Strictly control the amount of water added, 12-13%, more will affect the hardness

7. Polymer insulation mortar formulation
42.5 Cement: 400kg

Washing sand 60-120 mesh: 600kg

Latex powder: 12-15kg

HPMC: 2-3kg

Wood fiber: 2-3kg

Once the ingredients have been selected, they must be properly mixed. This is done by first combining the dry ingredients in a mixer. The ingredients are then mixed until they form a homogeneous mixture. The mixture is then poured into a container and left to set.

Once the mixture has set, it is ready to be applied to the surface. This is done by using a trowel or other tool to spread the mortar evenly over the surface. The mortar should be applied in thin layers and allowed to dry before the next layer is applied.

The final step in the formulation of dry mixed mortar is the curing process. This is done by allowing the mortar to dry completely before it is exposed to moisture. This helps to ensure that the mortar has the desired strength and durability.

The formulation of dry mixed mortar is an important part of any construction project. It is important to select the right ingredients, mix them correctly, and apply the mortar correctly in order to ensure that the project is successful. By following the steps outlined above, you can ensure that your project will be successful and that the mortar will last for years to come.
