- Q: Waterproof engineering should be arranged at what time to do the best?
- Look at what material, the real cement-based infiltration of crystalline waterproof material twisted Fu Huang Piling a good standard pupil Paste can be done, we have an admixture directly into the concrete, the warranty for 25 years, do not have to do the time to do! what!
- Q: Have you heard of waterproof building materials? What are the characteristics of who
- Building materials can be divided into structural materials, decorative materials and some special materials
- Q: What is good for roof waterproofing? Coil or waterproof paint ah?
- Roof waterproofing can not use a single waterproof material, must be rigid and flexible combination of construction 1. The first layer of flexible waterproof, such as waterproof coating. 2. The second time to do mortar waterproof, as a copy of the Dan Dan light chi chi corpse built a layer of protective layer. Flexible waterproof tensile elongation, a little bit of settlement or deformation will not damage the waterproof layer. Rigid waterproof (ie mortar waterproofing agent) waterproof at the same time, can play a protective role, waterproof layer is not easy to be destroyed. If the roof area is not particularly large, it is recommended to use waterproof coating (must choose flexible), good waterproof coating waterproof life than the long, and some environmental protection. Above do mortar waterproof as a protection. If you want to buy the coil, then, in particular, pay attention to the market a lot of waste plastic is made, the water cycle is even shorter. , Note: Be sure to buy regular manufacturers of regular products. And to standard construction.
- Q: M10 mortar mix design and raw material test a total of how much material?
- Should be enough In fact, the laboratory is not the number of the main time in the inspection when the cement should be sieved
- Q: It seems to see a piece of information is 30 tons of twitch 紶 陛 cough pile correction point hole bowl film once, I now do are mortar test block test, ask the master, it is best to check that is not the supervision Sick of more
- Not the necessary, mortar raw materials according to the design requirements of the ratio, and now a lot of local mortar raw materials are not for inspection, but to do with the ratio, mortar test block production should be negotiated with the supervision of the production by inspection, for example, An inspection lot, or two, not on the number of tons, is on the building area to count
- Q: Stir the mortar to add any material into the mortar to use
- , Masonry mortar () mortar raw materials required by the use of raw materials must be tested according to the current standards of qualified use (b) mortar with the ratio of compliance
- Q: What are the reasons for the cracking of the exterior wall insulation
- to take impatient putty: As putty intolerant water, when the water is often impregnated after the bubble cracking
- Q: Insulation putty can be used alone as an external wall insulation material? Whether the external wall insulation putty can replace the external wall mortar
- First of all, you can not replace the insulation material insulation, and many products in the development process slowly with the time will reflect their own shortcomings, insulation board has now been recognized by the state, and Insulation putty is not able to achieve the quality of the real ability to quantify. Insulation board normal life can reach 20 years, up to 30 years, the life of insulation putty is also 20 years, high water resistance can reach 30 years. Insulation putty can not be too thick construction, too thick easy to crack off, large area with the visual plane effect is poor. And the insulation board in the thickness of the greater arbitrariness, the insulation board in the construction of Ji Ji reclamation killing the old ghost tame handmade foam can make a large area of ??the wall is more smooth, of course, relatively heat putty, the construction cost is higher. But the two are complementary in the building, a small area more difficult to build the edge of the construction site, available insulation putty, large selection of insulation board, of course, for some of the insulation requirements are not high can also use insulation putty. The insulation requirements of a little more choice of insulation board. Insulation putty can replace the mortar, the premise is not to do other work above the putty. I hope my answer will help you!
- Q: Do you install firewood in the door frame when installing the fire door? There is nothing related to the helium trace grams of grams of long-haun glory magic norms clearly can not or can. What is the specification number? (03j609 Atlas shows C20 cement mortar) Thank you more
- Since the implementation of the new fire door standard in 2008 after the implementation of the fire door (including the door frame filled) in the non-helium trace grams of the United States and the United States and the United States and the use of rock wool or aluminum silicate cotton and other harmful fiber filler The The relevant environmental requirements of the country also have the same requirements.
- Q: Wall whitewash with 114 mixed mortar, no lime cream can be used to replace what other materials
- It is recommended that you choose the product of Dongfang Yuhong Spraying Polyurea Supporting Material Rainbow PUP-261 Epoxy Primer is made of epoxy resin, curing agent, thinner and additives and other components for a concrete base Closed primer
