What material is good for bathroom backfill? Do you have to use ceramsite?

Bathroom backfill, now commonly used materials are building slag, cinder, ceramsite, lime, fine river sand, etc., what materials are used for backfilling, if you don't consider the cost then ceramsite is the best, but the cost is also the highest. Now it is generally used more than building slag, cinder, etc., but it is especially reminded that large pieces and sharp screening out, so as not to puncture the pipe and waterproof layer at that time.

Ceramsite is an artificial light aggregate (light aggregate).

The outer shell is hard, with a water-retaining glaze layer on the surface and a microporous ceramic granular inside. It has good physical, chemical and hydraulic properties, large specific surface area, high porosity, and strong adsorption and dirt interception capacity. Its surface is porous, angular, and rough.

Because of these characteristics, ceramsite is often used in backfilling sunken basements

First, it is light weight: the thickness of the bathroom with sunken design is generally 400mm 450mm; If the weight of the material is large, it will cause cracks in the floor slab, which is not good for waterproofing. The use of ceramsite makes full use of its light weight.

2. Moisture absorption: The inside of the ceramsite has microporous ceramic particles, which can achieve the effect of moisture absorption, which is undoubtedly beneficial to the environment of the bathroom.

3. Easy to maintain: because it is easy to excavate, it is more convenient to use other materials for maintenance.

4. In addition, other characteristics such as strong adsorption and dirt interception ability, good physical, chemical and hydraulic properties of ceramsite are suitable filling materials for the specific environment of the bathroom.

What materials are good for bathroom backfill, construction waste and ceramsite will be eliminated, see the latest materials.

We have three key points for our requirements for toilet backfill materials: 1. The material is environmentally friendly and lightweight, the material is environmentally friendly so that it will not corrode the pipeline, and the light weight will not overburden the caisson and cause potential safety hazards. 2. The process procedure should be simple and repaired is not difficult.

The existing standard ceramsite process takes 7 days to complete and then apply tiles. 3. The material does not absorb water and seepage. The material absorbs water and is easy to produce peculiar smell (the bathroom is a variety of water mixed and infiltrated into the caisson), once the ceramsite and construction waste absorb too much, generally one cubic is about two tons of weight, that is, it is easy to block the pipe, and it is easy to cause water leakage and seepage to the room below, and it is easy to produce potential safety hazards.

In fact, ceramsite is also not environmentally friendly and easily absorbs water. At present, the best material on the market should be the material of cement foaming, through the use of special additives to make cement foam into density, high quality and light environmental protection and safety materials, coupled with the improvement of equipment and technology, it is currently the safest and most reliable, can comprehensively solve the existing problems. P.S

It seems that there is a patented technology, and it should not be widely circulated in the market at present, and I watched TV and related news, it seems to be Hunan Fumin Le Building Materials Technology Company.
