What are the advantages of cement blanket?

The invention of the new material cement blanket can serve the daily construction of all of us well. Cement blanket manufacturers tell you about how to use cement blanket

1 The size of cement blanket is cut, and the size of cement blanket can be determined according to the size of the construction site, and cut at will.

2. Cement blankets can be widely used in railways, highways, water conservancy, agricultural irrigation and other fields, wherever you want. The cement blanket not only saves 90% of the material, but also shortens the construction period by 60%. The cement blanket has been valued at more than 100 million yuan, and even the United States is buying in large quantities and widely used. There is the existence of fiber skeleton, and the uniformity of the concrete powder, this material will basically not crack after solidification, and the service life is long. The cement blanket is stored and transported like cloth, and it is also very convenient to lay. 2 The advantage of cement blanket is easy construction, the disadvantage is low bending strength and strict construction requirements. Concrete canvas usually looks like an ordinary blanket.

Hanji cement blanket laying construction

1. Preparation

First, plan and measure to ensure a certain slope, so that the water can flow smoothly from the upper end to the lower end; second, after the construction site is cleaned and leveled, the construction line is set according to the design drawing, and the drainage slope is remeasured.

2. Excavation

Set up the construction line according to the design requirements, the two sides of the ditch need to be leveled, and the slope inside the ditch must be free of empty soil and voids. The water damage parts shall be tamped, except for the debris and gravel in the slope. If necessary, use Sanqi lime soil for tamping, or grouting for reinforcement and then close it. It is required that the treated parts have good stability!

3. Laying

The material can be laid vertically and horizontally. Please be sure to flatten the substrate, otherwise it will affect the appearance quality!

4. Seam treatment

1. Dig the pits with a width of 10 cm and a depth of twice the depth of the cement blanket at the overlapping positions of the two adjacent cement blankets. Put the cement blanket joints at the overlapping positions and flatten them.

2. Press the upper cement blanket on the lower cement blanket in the direction of the water flow, and the overlap should not be less than 10cm.

3. Evenly apply sealant on the joints.

4. Fix two cement blankets with Φ 5*38mm stainless steel screws.

5. Groove treatment

Use rivets to fix the edge of the material on the edge of the ditch, and also use rivets to fix the overlap. After fixing, cover the edge with soil.

6. Water curing

Before the watering, the entire paving needs to be inspected and accepted, and only after passing the water! It needs to be watered 9kg per square (thickness is calculated by 10mm). It is necessary to pour through. It is necessary to sprinkle water evenly from the edge to the middle. It is best to use spraying method. The flow rate is 4000ml/min until the cement blanket becomes darker. Do not use water column with high pressure! It is forbidden to step on after watering. When the temperature is ≤5℃, heat preservation measures should be taken; when the average day and night temperature is higher than 30℃, the surface should be covered with plastic film or geotextile and other materials to keep it moist, and the water curing time should not be less than 3 days
