Significance of Social Testing Prior To Construction

by Bikram Paul A Professional Blogger

Since all construction projects materialize on the soil, it’s imperative to check its quality thoroughly. The soil has to bear the weight of the concrete structures so testing is chiefly done to assess the bearing capacity. The chemical and physical composition of the soil is examined during this course. In fact, the quality of soil not only decides the bearing capability but it guarantees to determine the structure steadiness. Again, the size and penetration of the pillar are decided during the foundation basing upon the quality of the soil. In fact, the water level of the soil only can be determined from soil testing. Centered on the soil testing reports quality of material can be finalized like - if due to high moisture presence the area is susceptible to corrosion, then it is vital to select only corrosion-resistant TMT Bars from any of the top 10 steel companies in Andhra Pradesh for the construction. If the soil testing is avoided, the structure will be exposed to unidentified hazards and the result could be disastrous.

Now, let’s talk about diverse types of soil testing for construction -

● Gravity Test

Gravity of the soil means the ratio of unit weight of soil solids to that of the water.

There are few approaches by which the gravity test can be performed but Density Bottle Method and Pycnometer Method is the most simple and easy ones to receive  the precise result.

● Moisture Test

The extent of moisture content is possibly the lone most significant geotechnical test and has the benefit of being equally binding on distressed and untouched samples. Moisture content can be measured both in the field and in the laboratory. But the chance for inaccuracy exists where samples are not representative or when specimen and storing processes do not preserve the moisture content before the actual testing.

● Atterberg Limits Test

Atterberg limits test on the soil is executed at three levels. The constituent for testing is done with fine-grained soil and if any critical constituent from water is existing then it can be determined with it. The three limits that are assessed are -

·       Liquid Limit

·       Plastic Limit

·       Shrinkage Limit   

● Dry Density Test

Dry Density test in the soil is executed at two levels -

·       Core Cutter Method

·       Sand Replacement Method 

● Proctor’s Compaction Test

Compaction in the soil is one of the most significant elements that are to be discovered during Proctor’s Compaction Test on the soil. It is to do the densification by decreasing the air vacuums in soil. The level of Compaction is assessed as far as the dry thickness of soil.

The soil surveys or examination governs not only the bearing capacity of the soil but also the rate of settlement of the soil. This rate regulates the degree of structure stabilization on the soil. Apart from this, the construction material like kind of cement, quality of TMT rebars from any of the top 10 steel companies in Andhra Pradesh, and others are very much determined by the soil testing results.
