Our discussion today is the calculation of labor requirements and floor work materials, this flooring work includes backfill work, K-100 cast concrete, landfill sand and floor coating (ceramic size 40 x 40 cm).
At this early stage we should know in advance technical backfill work, landfill sand, K-100 cast concrete and floor coating.
a. Backfill work
@kharrazi ) took a few months ago on a construction project using a pocket cameraThe soil used must meet the technical specifications, the backfill compaction is done by means or manually, the backfill overlap is done by not accumulating in a particular field to facilitate the worker in the process of overlaying.
b. Landfill sand
The landfill sand in question is layered in layers and compacted manually or by means.
c. Concrete (K-100)
@kharrazi ) took a few months ago on a construction project using a pocket cameraThe foundry work begins by mixing the material in accordance with the specification until it becomes homogeneous, after the concrete mixture is stirred, it is poured into a bucket or a stroller and overlaid on the floor surface, when casting needs to be compacted by pounding the surface with wood so that cast gravel can be mutually filling and solid, on the surface that has been considered flat need to be made rough with broom stick.
d. Floor coating (Ceramic size 40 x 40 cm)
@kharrazi ) took a few months ago on a construction project using a pocket cameraFloor coating work that we will discuss is ceramic floor size 40 x 40 cm, this work started after the work of the cast floor is considered finished.
Ceramics will be lined with a layer of water mixed with cement, this mixture serves as a glue between the ceramic and the cast floor.
After the ceramic is dry and considered finished then the worker then insert ceramic gap with color cement so that ceramic not quickly damaged during expansion.
The use of ceramic floor is very common in Indonesia, ceramics have high flexibility and can be used in almost all rooms.
Another plus is, ceramic does not require polishing and has a low maintenance cost.
Currently ceramic is very easy to find on the market, various colors and textures we can choose to make ceramics cheap choice of users.

The calculation of the need for floor work is just an example and can be used especially to young engineers and lay people, analysis of labor and material needs calculations on this work using the analysis of Indonesian National Standard, can be developed as needed.
This is all I can write right now, for all the lack of writing and as a servant of God I apologize.
