What are the physical performance indicators of asphalt waterproofing membrane that should be inspec

Asphalt waterproofing membrane is suitable for industrial and civil buildings such as roofs, basements, walls, toilets, pools, canals, subways, caverns, highways, bridges and airport runways and other waterproof protection projects.

Answer: B, C, D, E

The physical properties of polymer modified asphalt waterproofing membrane include impermeability, heat resistance, elongation, and low temperature of stuffy matter.

Answer]: The atmospheric stability of the waterproofing membrane is often expressed by indicators such as aging resistance and performance retention rate after aging.

Answer]: The main properties of the waterproof membrane include: (1) Waterproofness:

It is often expressed in indicators such as impermeability and permeability; (2) Mechanical and mechanical properties: tensile force, tensile degree and elongation at break are commonly used; (3) Temperature stability: commonly used to express heat resistance, heat resistance, brittle temperature and other indicators; (4) Qualitative atmospheric spike:

It is commonly used to express aging resistance, performance retention rate after aging and other indicators; (5) Flexibility: Commonly used indicators such as flexibility, low-temperature bendability, and flexibility.

1. Empty drum:The waterproof layer hollowing drum generally occurs between the leveling layer and the waterproof layer of the coating film and the joints, the reason is that the moisture content of the base layer is too large, so that the coating film is hollow and forms bubbles, so we should control the water-containing smile rate in the construction and operate carefully.

2. Leakage:The leakage of the waterproof layer mostly occurs in the pipe roots, floor drains, sanitary ware and yin and yang corners that pass through the floor slab, because the pipe roots, floor drains and other parts are loose, the bonding is not firm, the painting is not tight or the waterproof layer is partially damaged, resulting in voids, and the lap length of the parts is not enough at the joint seal. Before the construction of the coating film waterproof layer, it must be carefully inspected and repaired.

3. Puncture:The waterproof layer generated by the coating film waterproofing is too weak, it is easy to be punctured, if there is unfortunate sand under the feet, it will break when you step on it, the user should pay attention to this problem, and remember to do a protective layer after the construction.

Precautions for the construction of asphalt waterproofing membrane.

Before construction, we need to make corresponding preparations, such as preparing construction drawings, construction materials, etc., and then we need to review the drawings, understand the waterproof details and technical requirements in the construction drawings, and prepare the construction plan and technical measures of the waterproof project.

The waterproof material used should have a factory certificate of conformity, and the material must meet the design requirements before entering the construction site. The waterproofing project must be constructed by the waterproofing professional team, and it is best to hold a professional qualification certificate of workers to work on the waterproof project to ensure the construction quality of the waterproof project.

Answer: Brigade Fighting Case] :d

Textbook p154. The polymer-modified asphalt waterproofing membrane has the characteristics of no flow at high temperature, no brittleness at low temperature, high tensile strength and large elongation.

The areal density of the asphalt waterproofing membrane reflects the construction and use performance of the waterproofing membrane under low temperature clearance. Impermeable. Impermeability refers to the performance of the waterproofing membrane at a certain water pressure (hydrostatic pressure or dynamic water pressure) and without leakage within a certain period of time.

What is the effect of areal density on the performance of asphalt waterproofing membrane? Answer: The effect of areal density on the performance of asphalt anti-water membrane:

1.The asphalt waterproofing membrane has strong temperature sensitivity, and the ambient temperature has a great influence on the test results. Therefore, before starting the test, it is necessary to place the specimen in a dry place, especially for the specimen that is subjected to the tensile test.

2.In the process of physical property test, clean fresh water or distilled water should be selected for the impermeable test, if the water quality is unclear or unclean water is used, the specimen covering layer will be produced with the relevant components present in the water. Cave Jane Dust.
