As the grid sampling is becoming popular, several people have started taking more soil samples with keen interest. This situation brings more queries about soil labs like why these labs are getting distinct results for the same field and same sample, why recommendations for using fertilizer vary from labs to labs.

Why Construction Sector Requires Soil Testing Equipments?

Builders and construction sector requires soil testing equipments to test the soil for deep foundations. Now you may wonder what it is. Deep foundations are those where the foundation depth is usually greater than twice of footing width (D= 2B). There is a need of deep foundations because of several reasons. In this article, we will learn about all those reasons and types of deep foundations.

When the depth and composition of the bearing layer for shallow foundations are not similar at one site to another, most pile foundations encounter same deposits. As capacity of pile based on parameters of the soil is unreliable from load tests, it is crucial to avail complete information on the size, type, length, and capacity of piles.

Corresponding load tests and correlation of soil features need to be consider as it will help in deciding the soil type test that has to be performed. This also helps in making reasonable recommendation for size, type, capacity and length of piles.

Why construction sector requires soil testing equipments?

Another reason could be- if information about piles in the locality is unavailable or unreliable. It it happens, it will be necessary to drive a test pile and compare with soil data.

Various test methods done by soil testing instruments-

  • CPT – Cone penetration test – it is used to determine the cohesion for soft cohesive soils and to ensure with SPT result for fine to coarse sands.
  • SPT- Standard penetration test to find the cohesion to determine the friction angle for each soil stratum.
  • Vane shear test- it is meant for impervious clayey soil
  • Self boring pressure meter test- it is used to determine modulus of sub grade reaction for horizontal deflection for stiffer cohesive soils, granular soil, weathered rock and soft rock.

All these tests are significant for construction sector and are done with the help of specialized soil testing equipment.

How Concrete Testing Equipment Helps In Measuring Workability Of The Concrete?

There are several testing methods to check distinct parameters of the concrete. To measure workability of the concrete, there is a test method called concrete slump test performed by specialized concrete testing equipment. It is empirical test to measure workability of the fresh concrete. The testing method is used to measure the consistency of concrete in that particular batch. It is performed by talented workforce to check consistency of the freshly prepared concrete, which is further used for building structures.

How Concrete Testing Equipment Helps In Measuring Workability Of The Concrete?
What is consistency? It is an ease or simplicity or wetness of the concrete. The test is known and practiced by people due to its easy handling of apparatus and simple procedure. However, this convenience of the test method often lets a wide variability in the manner in which the test is performed. The slump test method is used by professionals to ensure uniformity for every batch of concrete under field conditions and to check and analyze the impact of plasticizers on their introduction.

Apparatus required for testing

There is a requirement of metal mould of cone frustum shape having both ends open. This mould is easy to grip, top internal diameter 4”, and bottom 8” with 1ft height.  2 ft long bullet nosed metal rod is also required with 16mm diameter.

Interpretation of results

The slumped concrete mixture takes several shapes and according to the slumped concrete profile, the slump is known as true slump, collapse slump, or shear slump. When you achieve a shear or collapse slump, you can take a fresh sample and perform the test again. A collapse slump reveals the too much wetness of the mix.

Collapse slump usually has high workability and in such case, slump test becomes a waste of time. Contractors use very dry mixes with slump 0-25mm to make roads.

Is there any limitation of a slump test?

The slump test is suitable for medium to high workability slump. It is limited to concrete made of aggregates having less than 38mm.

You can source concrete testing equipment from renowned supplier like EIE instruments. They are offering best quality, robust in performance equipments to perform distinct concrete tests. Mail your requirements and avail quotes from experts.

How TDS Checker Instrument Helps In Soil Testing?

TDS checking device is one of the useful soil testing instruments that checks total dissolved solids in water. Dissolved solids are any minerals, metals, salts, anions or cations dissolved in water. It includes anything dissolved in water other than the H20 molecule and suspended solids. This device is based on the electrical conductivity (EC) of water. Pure H20 has zero conductivity. TDS checking device is evaluated by converting the EC by a factor of 0.5 to 1.0 times the EC, relying on the levels.

How TDS checker instrument helps in soil testing?

Where do these dissolved solids come from?

  • Organic sources like leaves, plankton, silt, and industrial sewage and waste are the reasons behind dissolved solids. Some of the dissolved solids come from fertilizers, road salts, and pesticides used on farms and lawns.
  • Inorganic materials like rocks and air can be also a source of dissolved solids as they may contain nitrogen, calcium bicarbonate, iron phosphorous, sulfur, and more other things. These things form salts that further make water ionic. Ions are the particles that have a negative or positive charge.

How it is helpful?

There are many reasons that explain why TDS checking is often helpful. A few of the reasons are as under-

Taste and health- High TDS amount leads to undesirable taste that could be bitter, salty, or metallic. We all are affected by toxic chemicals and minerals found in the air and our food on regular basis. Drinking pure water is the only way to expel these toxins from the body. So, TDS checking meter will help you in determining the TDS level in water. You can treat your water and have purer water for drinking.

Filter performance- If you are using water purifier, you need to check the water it produces often to ensure its performance. Lower TDS shows that the water has minimum microorganisms and other harmful non-solids like fluorine and chlorine.

Hardness- Hardness in drinking water is usually caused by magnesium and calcium. These are two nontoxic natural minerals in water. Hard water doesn’t lather soap, leave spots on dishware, and may also cause scaling on drain, pipe, and valve.

Manufacturers and suppliers of soil testing equipment are also offering TDS checking devices to their clients. You can call or mail them any time and avail the premium instruments at relatively cheap prices.

How To Test The Strength Of Hardened Concrete With Testing Instruments?

There are several ways to test the strength of hardened concrete. In this article, we will explain the two methods that include testing cylinders and beams. Some of the testing methods are non destructive and some are bit destructive, leaving holes that are relatively smaller in size and easily patched. Technicians performing these tests are qualified to use concrete testing instruments and have the apt certifications from standard ASTM test methods.

Concrete Testing Instruments
Test cylinders

The easiest and mostly used testing method is testing cylinders and making it of fresh, consolidated concrete and testing the hardened specimen at the specified age.

You will be required cylindrical molds for casting strength specimens and these molds should have a height-to-diameter ration of 2:1. Cylinders made with ASTM C31 can be tested for compressive strength and tested for modules of elasticity. You can place the cylinders horizontally and test them for splitting tensile strength.

It is always better not to use impervious (plastic) molds for forming masonry grout specimens.

Beams

Beam specimen of concrete should be cast as per ASTM C31, and the hardened in the horizontal position are used for performing flexural strength testing.

A usual size of beam mold is 6×6 inches and 20-21 inches long. Beams are widely used for pavements and slabs. Flexural strength is often tested by technicians using 3rd point loading and is specified by the FAA for airport pavements.
