Exterior wall insulation mortar formula, exterior wall insulation mortar practice?

Thermal insulation mortar is a kind of ready-mixed dry mortar made of various lightweight materials as aggregates, cement as cement, mixed with some modified additives, and stirred and mixed by production enterprises. A building material used to construct the surface insulation layer of a building. If you want to engage in production, if you have a sample that you are satisfied with, we can help you determine the proportion of each ingredient through microscopic analysis, carry out formula restoration, and then provide corresponding raw material recommendations and technical support in the later stage.

How to produce Mortar King.

1. Mortar King Formula:

1) Production of ordinary mortar king: mortar king masterbatch + base material (fly ash, stone powder, talcum powder, calcium powder, laterite powder, fine sand) = mortar king.

2) Production of water-retaining mortar king: mortar king masterbatch + base material (fly ash, stone powder, talcum powder, calcium powder, laterite powder, fine sand can be) + general masterbatch of building admixtures = water-retaining mortar king.

3) Production of thermal insulation mortar: mortar king + foam board fine particles (the machine directly crushes the foam board) = thermal insulation mortar.

4) Production of anti-cracking mortar: mortar king + fiber (polypropylene staple fiber, glass fiber and other staple fibers) = anti-cracking mortar.

2. Base materials: fly ash, stone powder, talcum powder, calcium powder, laterite powder, fine sand and other hard materials, they only play a filling role, and the real role is the high foaming effect of the mortar king masterbatch. The ** of the base material is 100 yuan per ton, which will vary from place to place.

3. Core material: there are two kinds: mortar queen mother material and concentrated mortar queen mother material.

4. The ratio of base material and mortar masterbatch: the conventional is to put 20-30 kg of mortar masterbatch per ton of base material (15-20 kg of concentrated mortar masterbatch), and how much mortar masterbatch can be added per ton of base material.

5. Production method: fully mix the base material + mortar masterbatch and stir evenly. First put the base material into the gravity cone mixer, then add the mortar master material, and stir it well.

6. Mixing equipment: gravity cone mixer, conditional machine mixing, unconditional manual shovel mixing.

7. Packing: woven bags (old bags, new bags), woven bags can be added with a plastic inner film bag (pieces) in order to prevent moisture.

8. Packet sealing (hand-held packet machine: 160 yuan).

9. Cost control: the cost per ton is controlled within 350 yuan.

Cost Control Methods:

1) The cost of base material is controlled at 100 yuan per ton.

2) 25 kg per ton of base material plus mortar master material, cost: 150 yuan.

3) Kilograms of general masterbatch per ton of base material plus building admixture, cost: 35 yuan.

4) The cost of each ton of packaging and inner and outer bags is 40 yuan.

5) Total cost: 325 yuan per ton.

10. The cost of producing insulation mortar and anti-crack mortar plus foam board fines and fibers is enough.

The above ratio can be adjusted according to the market ** and quality requirements, and the test is carried out before production, so that the local market can recognize your quality before large-scale production.

The practice of exterior wall insulation mortar is very important, and every detail of the practice is the summary of countless experiences of predecessors, which is very useful to achieve the best results. Zhongda Consulting will give you a detailed introduction to the practice of exterior wall insulation mortar.

First, the exterior wall practice.

1. Grassroots treatment.

a, the surface of the structural concrete is cleaned with water floating dust, the holes through the wall are blocked with foam expansion agent to the surface of 8 10 deep not less than 50 50 squares and compacted without cracks, and all holes embedded in the outer wall are made of C20 fine stone concrete after being blocked twice with waterproof mortar higher than the original base layer, and the same method of penetrating the wall holes;

B, cold bridge part: that is, concrete and brick masonry or two different materials connected to the part, mining and destroying Hui with 1: cement mortar mixed with water proportion of 4 10% of the 901 glue scraping, after the alkali-resistant glass fiber mesh is swept, and watering and maintenance shall not be less than 3 days;

c. Texturing treatment, by the professional team, the liquid interface agent is used to spray the concrete surface, and the base layer can be painted after the watering and curing reaches the strength;

D, do ash cake to find the rules, after the acceptance of the main structure, first of all, the details of the structure for a comprehensive review, according to the overall verticality of the exterior wall, flatness, the actual situation of the structure of the decorative lines of the comprehensive consideration of the thickness of the base layer of the plaster, strict control of the base layer of the rough ash cake height.

2. Rough scratching of the base layer.

The use of 1:3 cement mortar powder to the base ash cake height flat, with wood crab rubbing to pull out the texture or sweep hair (concrete surface without powder thickness can be free of powder), there shall be no protrusion or recess into the base ash cake phenomenon, to ensure that the thickness of the insulation mortar meets the design and specification requirements, in the same visible base rough ash cake must be on the same façade. The basic brown powder should be watered and maintained in time after 24 hours, not less than 1 time a day.

3. Powder exterior wall insulation mortar and surface layer anti-cracking mortar.

According to the energy-saving design requirements, the exterior walls of the east, west and south sides of the building are made of 25-thick HL exterior wall insulation mortar; The exterior wall on the north side is made of 38 thick HL exterior wall insulation mortar. Now according to the thickness of the façade insulation mortar of the exterior wall in time to make the ash cake of the insulation mortar surface on the rough surface of the base layer, and then make a large corner protection, the corner protection in the construction, because the thickness of the corner protection stucco is thicker, it must be carried out in layers, it is strictly forbidden to form at one time, and dry cement is not allowed. The lattice joints of the anti-cracking mortar surface layer are set with reference to the drawings and the design façade requirements are determined on the spot according to the actual liquid answering situation.

For specific practices, please refer to the "HL Energy-saving Exterior Wall Insulation Mortar Construction Plan" (insulation mortar and surface layer construction according to relevant requirements and specifications).
