Materials Testing Glossary - Building Terms Explained
There is an extensive set of building industry terms concerning materials testing and the various equipment used. To assist those who are unfamiliar with them, here’s a list of the most common ones.
This involves the deliberate injection of microscopic air bubbles into a concrete mix through the addition of an air entraining solution. The purposes of this procedure is to improve the usefulness of the compound and its resistance to wear and tear, once it has set. The bubbles help to reduce friction between the base elements of the concrete mix, such as crushed stones, gravel etc and are also used to effectively soak up the various stresses that result when the mix expands or contracts.
This is defined as the maximum load and stress that a material can be subjected to, before it fails. Compression is the direct result of pressure and materials that are subjected to pressure that exceeds their compressive strength, often undergo deformation. For this reason, analysing a material to find out its compressive strength is vital for creating robust buildings, just as it is for discovering the strength of existing members.
The means of sustaining the necessary level of moisture and heat levels throughout a slab of newly placed and finished concrete. Precise curing is imperative for allowing constant hydration, strength evolvement, slab cohesion, protection against freezing and thawing, as well as safeguarding the concrete against unwanted erosion.
The time required to cure concrete depends on a wide range of factors, such as environmental conditions, overall size of the concrete, it’s strength, it’s mixture and so on. The curing procedure can involve a number of different methods. Ensuring a consistent level of moisture for a concrete element can be achieved by spraying and fogging, placing plastic or paper sheets on top of the area or by utilising left in place forms, which deliver adequate shelter for concrete, from moisture reduction.
An asphalt substance that results from the addition of small volumes of air and water to hot bitumen. When water is combined with bitumen at a suitably high pressure, it instantly vaporises, forming bubbles wrapped in oil. This process prompts the bitumen to rapidly increase in volume, to around 20 times its original size, reducing its density. Once the solution has expanded, its injected via nozzles into a mixer, that merges the new mixture with other aggregate materials, such as gravel, crushed stone, sand etc. The resulting compound is flexible and moisture resistant, making it perfect for surfacing new areas or renewing older ones.
A non-invasive mechanism used to identify reinforced steel bars within concrete. The apparatus creates a magnetic field and analyses the response between the magnetic field and metals within the concrete. Based on this response, the gadget can then calculate the size of the reinforced steel, the spacing, configuration and more.
A simple gadget used for determining how deep a particular soil material can be penetrated. This is useful for identifying whether a soil is suitable for the construction of a new road surface or not.
An analysis procedure performed by materials testing companies, that inspects and assesses the various physical qualities of structures. This helps to reveal and pinpoint any areas of underlying weakness and decay. The outcome of the analysis helps engineers to decide on appropriate measures to take for fixing structural members.
A device used to calculate and compare the density of solid materials.
A structure whose purpose is to withstand shear forces. Such structures reverse the results of lateral loads imposed on a member.
The measure of a material’s resistance to pulling or stretching, before it fails.
Work platforms and mobile access ramps allow personnel to complete their duties safely and effectively in even the most difficult circumstances. The loading and unloading of cargo on large commercial vehicles and train carriages, for example, creates a dangerous set of risks
When shopping for new or replacement windows, one very important factor to consider is the window frame material. The frame is a structural backbone of a window, choosing the proper frame material for your project will ensure the windows will function for decades rather than years.
There are a whole range of different work platforms available on the market today, including Mobile Elevated Work Platforms, scaffolding, or prefabricated platforms that are intended to be installed on a permanent basis. The style of the platform you require will come down to the nature of the work that needs to be completed
Enabling workers to safely get on and get off a large, commercial truck or similar vehicle is essential to preventing unnecessary injuries. While everyone would be quick to acknowledge the importance of implementing such equipment, very few would understand the components that are required to make truck access platforms safe and dependable.
If ever you’ve asked a materials testing specialist this same question, you’ll know that their response has only succeeded in creating even more confusion. The reason for this is that concrete is a very complex subject and there loads of different factors and conditions that must be taken into account.
Dyeing is a process that unleashes the power of dyes to transform colourless fibres into beautifully coloured pieces. The effective rate of dyes depends upon the reactive dyes manufacturer.
Although rolling mills have very simple construction, still they are a “must-have” tool in the metalworking workshop. Rolling mills are machines with two rolls that are used to deform the metal and then reshape it. Rolling mills are used to adjust the thickness and length of the material as per need.
A cooling tower is a machine, which is used to get rid of the heat that utilizes water to route the unnecessary heat into the environment. The basic principle on which the cooling towers work is that heat is removed with the help of water by evaporating a small amount of water and then re-circulated through the unit to cool it down.
