One of the prerequisites to ensure that construction works in general and factory building in particular last for a long time is the compacted and solid ground or road structure. . This is one of the prerequisite and mandatory processes. Let's learn through the actual compaction process at the factory construction site.
The process of compaction of block grade rock bed
This procedure is specified from the test of compaction of material samples, reinforced soil, grade of natural stone ... in the laboratory to determine the best compaction moisture value and maximum dry volumetric weight of the material used. Use the foundation, the foundation of love.
Depending on the compaction, type of punch, compaction can be done by two methods: Standard compaction method 1; Modified compaction method 2.
Depending on the largest particle size in the test and the type of mortar used when compacting the sample, each standard compaction and improved compaction method is divided into two types of compaction, denoted A and D. In total, there are two types of compaction. Four different compaction methods are denoted as I-A, I-D, II-A, II-D. The technical parameters corresponding to the 4 compaction methods are detailed in Table 1.
Table 1. Technical parameters corresponding to the 4 compaction methods
For each specific material, the room compaction test is conducted according to one of the four methods mentioned above and specified in the acceptance construction process or the project's technical instructions.
Correction of compaction results in the laboratory for construction and acceptance: in practice, materials used in the field often contain a certain amount of oversized particles, so the volumetric value The maximum dry weight and best moisture content according to the room compaction results will be different from the maximum dry mass and best humidity values in the field; Therefore, it is necessary to calibrate the results of compaction in the room to give the field compaction parameters the maximum dry volumetric value, the best moisture content has been adjusted accordingly.
