Q:1: 8 cement ceramic particles to find how to set the amount of slope set
1: 8 cement ceramic particles to find slope layer, according to the amount of 1: 8 cement vermiculite with the amount of vermiculite in the calculation (that is, each cubic 1: 8 cement ceramsite, cement 0.175t, ceramic 1.02 cubic). 1: 8 cement ceramsite to find slope layer cover roof insulation layer quota, and then adjust the material spread, or the preparation of supplementary quotas. The quota is a standard that sets the amount of resources consumed by a unit of qualified products in a reasonable manner and rational use of materials and machinery. It reflects the level of social productivity in a given period. For each construction project, the amount of labor is measured, including basic and other labor. Plus the material of this project, including basic materials and other materials. For the labor unit price, is based on the local labor value of different types of work, the value of the material is based on the pre-market price to develop the budget price.
Q:What is the best bathroom waterproof material? Whether the bathroom is a web or a paint
Bathroom waterproof really worth noting. The bathroom to do the lack of water to remind the Jujiao angle drowned with hair, in addition to materials, is the waterproof process.

Q:What kind of waterproof material is used for waterproofing in basement?
Basement waterproofing common waterproof material is waterproofing membrane, waterproof coating and mortar waterproofing agent. The basement itself is relatively dark and humid, and the area is generally relatively small, yin and yang angle, pipe and other places are more, if the use of waterproofing membrane is not only not easy to paste paste, the construction of workers technical requirements are relatively high, and because it is used The indoor may be pungent odor is not enough environmentally friendly. So now more commonly used is the waterproof coating and mortar waterproofing agent, waterproof coating relative to the sand and cold workers in addition to the shortage of waste water for the limited strength, brushing the waterproof coating after the need to do a mortar protective layer, so Combined with the ease of construction, the length of the waterproof life, the cost of the point of view, mortar waterproofing agent is now the most suitable material, the cost is the lowest of the three.
Q:Promise insulation mortar and hollow glass beads non-polar insulation mortar What is the difference
Glassy beads is a kind of environmentally friendly new type of inorganic light insulation material, in addition to a light weight, insulation, insulation, fire excellent performance, but also has not burned, high strength, low water absorption, easy and good life Long advantage
