What’s The Purpose Of Non Destructive Testing Equipment?

NDT methods are performed with non destructive testing equipment to know the quality and condition of concrete, without damaging or tempering the concrete. There are few NDT methods that may be performed to find the location and development of cracks and invisible voids at the concrete surface as these things affect the structural or durability performance of concrete.

As these methods are specialized and performed with specific equipment, operators need to be well trained and familiar with the functions of the equipments and all factors that affect test conditions. They are also able to understand readings and responses obtained from the methods. Results must be evaluated and interpreted properly by professionals who are aware of the certain NDT technique.

Every NDT method has its limitations and benefits. It is always important to avoid any negative influences like weather conditions, and to know the limits of the testing method for various objects. There are some NDT methods that are comparative and dependent on a reference sample, such as a flawless item or a test series of cylinders to make the base response.

Some testing methods are-

• Penetration tests

The Windsor probe is usually considered as the best way to test penetration. Testing equipment has a powder-actuated gun or driver, loaded cartridges, hardened alloy probes, depth gauge for measuring probes penetration, and more related equipment.

This testing method has a potential to bring a quick means of determining quality and maturity of concrete. The test is non-destructive in nature.

• Dynamic tests

Ultrasonic pulse velocity method shows potential for testing strength of the concrete. With this method, experts measure the travel time of an ultrasonic pulse passing through the concrete. The time taken for the pulse is measured by electronic measuring circuits.

This method is ideal tool for finding the uniformity of the concrete. This method can be used on both existing and under construction structures.

All these methods are performed with specific non destructive testing equipment that is available in the market at hardware stores. You can find them online as well. EIE instruments suppliers are among pioneer reliable partners that offer premium range of NDT equipments at reasonable rates. Contact them and avail the products at least prices.

• 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.

Can Material Testing Equipment Help In Additive Tests?

Fiber material has been used to reinforce paving materials for long time in distinct parts of the world. These materials are great to use in stone matrix asphalt and open-graded mixtures to prevent draindown of the binder from aggregate particles. But nowadays, building and construction material makers have started using fibers in dense-graded mixtures to enhance stability and resistance to cracking. They use special material testing equipments to perform additive tests to determine strength of the material.

Let’s learn about fiber materials and mixtures used by them for asphalt preparation.

There are several forms and types of fibers used in asphalt mixtures, either regularly or experimentally. Among all the types of fibers, cellulose, polymer, and mineral fiber are most common.

Cellulose-  This fiber is sourced from woody plants; however, some are obtained from recycled newspapers. These fibers tend to be branching with high absorption. It means that this high absorbing nature helps cellulose fibers hold on to high binder contents in asphalt mixtures. These fibers are available in loose form or in pellets.

Mineral- Either it is natural or manufactured mineral fiber, both can be used for mixture. It is also known as mineral wool or rock wool, manufactured by melting minerals and later forming fibers through spinning or extruding methid. Minerals used to form mineral fibers involve slag or a blend of slag and rock, brucite, rock, steel, carbon, etc.

Synthetic polymer fibers- Polyester, aramid, polypropylene, and combinations of polymers are commonly used.

Plant based fibers- Such fibers are being used in more limited areas. These are obtained from woody fibers like jute, straw, and hemp, leaves, and seeds. They may also be fruit fibers, such as cotton, coconut, coir, and palm.

Specialized material testing equipments help in determining apt ratio of the fibers to make the mixture precise for construction purpose. Technicians know the way to test the asphalt mixture using these equipments. You can get in touch with them and get expert advice.

Specialized Road Tar Distillation Equipment From Bitumen Testing Products Range

Coal tar is a by-product which is extracted while processing coking coal into a specialized plant. It is further processed into quality coal tar and experts use tar distillation equipment to achieve desired chemical and physical properties. Many construction and coal industries have a complete range of bitumen testing equipments used for different purposes. Road tar distillation equipment is one of these equipments in which coal tar pitch is derived via processing of high temperature coal tar with the help of state-of-art technologies.

Coal tar is a dark viscous material that coal industries extract during the process of destructive distillation of coal. Professionals heat the coal at 1050 degrees Celsius and coke oven gas gets released. This gas holds valuable chemical compounds. They then cool down the hot coke oven gas to separate coal tar along with by-products, such as light oil, phenol, naphthalene, wash-oil, and anthracene.

Purification of tar is done in coal tar treatment plant that has a different section to separate the other chemical components. Tar having less than 4% moisture content is transported by pump to decanter of the section and later it is delivered by the plunger pump to pipe still furnace’s 1st stage and heated at 115 degrees to 130 degrees Celsius.

This heated coal tar is further sent to the evaporator and separated to liquid and vapor. Light oil has traces of naphthalene. They are removed from the evaporator’s top and sent to the condenser and cooler and later to a separator. This whole process involves lots of more steps to attain distilled coal tar.

This tar is later used for constructing roads in the cities of the countries. There are different grades of road tar available in the market. This bituminous material can be sourced from suppliers. However, only quality materials are further recommended for sale purposes as poor quality coal tar is also a reason behind failure of roads. Different grade of road tar has different uses, some are used for surface painting under normal and cold weather conditions, some are used for renewing coats, and some are used for premixing tar and for grouting.

You can approach bitumen testing equipment suppliers to get road tar distillation equipment. Some suppliers are offering their products worldwide; contact them and get the best deal.

How Petroleum Distillation Bitumen Testing Instrument Works?

Refining is a complex chemical method used for transforming crude oil with chemistry. To understand the working of petroleum distillation bitumen testing instrument, you will need to understand the basic chemistry first. 

Crude oil is composed of hydrocarbons. The chemical bonds linking the chain of carbon atoms and hydrogen atoms can be separated and linked in distinct ways. Hydrocarbon compound is the versatile one on the chemical charts that can make about 2.5 million possible combinations.

Use Mortar Testing Equipment To Determine Cement Or Mortar Compressive Strength

Builders and construction industry uses cement in the form of concrete or mortar. A mortar is a mixture of sand and cement in a certain ratio on which the mortar strength depends. Mortar is generally used for plastering and brick masonry.  Low compressive strength of the mortar makes it weak, while high compressive strength makes the mortar stronger. Mortar testing equipment helps workforce in determining the mortar compressive strength.

Which cement/concrete testing equipment is used for compressive strength test?

Accelerated curing tank is one of the cement/concrete testing equipments used for compressive strength test. The accelerated method is used to achieve high compressive strength in concrete. Experts also use this method to find out 28 days concrete compressive strength in 28 hours.
