Compression Testing of Construction Building Materials

Compression is a fundamental type of test used to characterize building materials in construction industry. Static compression tests apply an escalating compressive load until failure or apply a specific load and hold it for a certain period. Dynamic compression tests involve cycling between two (or more) load conditions. Depending on the nature of the specimen, compression tests can help determine the material’s ultimate yield strength, service life or other critical performance characteristics.

Fire Performance of Building Elements

The performance of walls, columns, floors and other building elements when exposed to fire conditions is of extreme importance in insuring safety to both the public and neighbouring structures. In order to acquire information on this performance, it is necessary to measure the fire-resistive properties of the materials and assemblies.

Fire Resistance Test Furnace for Vertical and Horizontal Test Specimens is the apparatus needed to evaluate the fire resistance of a horizontal or vertical construction assembly, column, or support, and provides a method of quantifying the ability of products such as doors and dampers, and building materials to withstand exposure to high temperatures. This is done by evaluating a number of performance elements such as; the load-bearing capacity, the ability to provide fire containment and the thermal transmittance of the materials and systems.

Building elements commonly tested include:
Fire Doors, Load Bearing Panel, Walls, Ventilation Ducts, Columns, Cable Barriers, Partitions. Dampers

  • Large Horizontal Scale Fire Resistance Test Furnace
  • Large Vertical Scale Fire Resistance Test Furnace
  • Hydraulic Tilting Fire Resistance Test Furnace
  • Indicative Fire Resistance Test Furnace
  • Miniature Fire Resistance Test Furnace

Non-Combustibility of Building Products

Non­-Combustibility Apparatus determines the non-combustibility performance, under specific conditions, of homogenous products and substantial components of non­homogeneous building products. This test is part of the requirements of the construction products regulation classification of reaction to fire performance for wall lining and roofing products and floorcoverings.

EN ISO 1182 Regulation classification criteria for all building products, has performance classes from A­F. Although another test is required for assessment, the non-combustibility apparatus is needed for qualifying all types of construction products to the highest performance criteria – A1 and A1fl (non-combustible). The classification criteria is shown in the table below. This principally applies to non­organic materials.

Measuring Heat of Combustion (Calorific Value)

The bomb calorimeter is the most common device for measuring the heat of combustion or calorific value of a material. With this apparatus a test specimen of specified mass is burned under standardized conditions.

The heat of combustion determined under these conditions is calculated based on the observed temperature rise while taking account of heat loss. The combustion process is initiated inside an atmosphere of oxygen in a constant volume container, the bomb, which is a vessel built to withstand high pressures. It is immersed in a stirred water bath, and the whole device is the calorimeter vessel. The calorimeter vessel is also immersed in an outer water bath. The water temperature in the calorimeter vessel and that of the outer bath are both monitored.

The Oxygen Bomb Calorimeter can be used to measure the heat generated from several applications and has been designed to conform to current ASTM, ISO, EN, BS and DIN international standards.

  • Building materials (EN ISO 1716)
  • Coal, coke (ASTM D5865)
  • Fuel (ASTM D240: gasoline, kerosene, fuel oil, Nos. 1D and 2D diesel fuel and Nos. 0GT, 1GT, and 2GT gas turbines fuels and ISO 1928)
  • Fuel derived from waste material (ASTM E711)
  • Hydrocarbon fuels (ASTM D4809)
  • Food, supplements, crops
  • Waste and refuse

Fire Behaviour of Building Products

Most construction products need to be tested and classified using a new test method called the Single Burning Item (the SBI) EN 13823. The construction products directive of the European commission will require that all European Member states eventually use this, instead of the traditional regulatory methods used in each country, to classify most building products.

The Commission recently defined the criteria for assessing building products into classes A-F. These are given in the table below. Though other test methods are required the SBI is needed to classify all non flooring products into the classes A2, B, C and D which are the major classes inhabited by most products other than those that are principally inorganic classified as non-combustible.

The Single Burning Item (SBI), is a method of test for determining the reaction to fire behaviour of building products (excluding floorings) when exposed to the thermal attack by a single burning item (a sand-box burner supplied with propane). The specimen is mounted on a trolley that is positioned in a frame beneath an exhaust system. The reaction of the specimen to the burner is monitored instrumentally and visually. Heat and smoke release rates are measured instrumentally, and physical characteristics are assessed by observation

Building and Construction Materials Testing

Partnering with UTEST, a leading manufacturer and supplier of testing equipment for construction materials, we are pleased to be able to offer material testing equipment to the construction industry.

Included in this range of equipment are solutions for testing aggregates, asphalt, bitumen, cement, and soil.

All the equipment are tested to guarantee quality, reliability and performance, and are backed by the international standards and warranties

UTEST frequently cooperates with the construction companies that carry out worldwide projects, private laboratories, universities and state institutions such as mineral research and exploration, road and highways, environment and city planning or hydraulics, irrigation and hydrology departments.

Our types of testing are as below:

UTEST Soil Testing Equipment are used for understanding and investigating the physical/mechanical properties, critical characteristic behaviours, performance of soil, unbound and hydraulically bound mixtures during compression, shear or inner liquid flow under dynamic and vibrating loading conditions. Soil characteristics are also used for deciding the most suitable method for excavating underground tunnels.

Every man-made structure needs a foundation that will resist to the exposed forces, such as live loads, dead loads and wind loads . The soil tests provide the engineering firms and construction companies with the ability to predict the mechanical behaviour of soils in order to design foundations that ensure resistance to forces likely to act upon it, including any unusual / extreme events such as earthquakes or hurricanes, thus providing a safe environment for people in or around the structures.

In the soil section, UTEST Testing Equipment is basically grouped in six main headings:

  • Field Inspection and Sampling
  • Laboratory Testing/Specimen Preparation
  • Soil Classification Tests
  • Soil Mechanic Tests
  • Compacted Road Base and Sub-Base Soils Tests
  • Soil Permeability and Dispersibility
  • Advanced Soil Testing Systems

Aggregates are fundamental materials that are used in all areas of construction industry such as concrete, mortars, bituminous mixtures, surface treatments for roads, airfields and other trafficked areas, railway ballast, unbound and hydraulic bound mixtures in civil engineering works and road constructions, which comprise our modern world as buildings, highways, dams, railways etc. Thus, it is crucial to determine the properties of aggregates according to related EN, ASTM, AASTHO, BS standards.

In the aggregate section, UTEST Testing Equipment is basically grouped in four main headings according to EN standards:

  • General and Geometrical Properties of Aggregates
  • Mechanical and Physical Properties of Aggregates
  • Thermal and Weathering Properties of Aggregates
  • Chemical Properties of Aggregates

Cement is the binder used to create concrete and mortar. The manufacture of cement requires stringent control, and a few tests are performed in cement plant laboratories to ensure that the cement is of the desired quality, that conforms to the requirements of the relevant standards.

The most important use of cement is the production of concrete and mortar, which are the combination of cement and an aggregate to form a strong building material that is durable in the face of normal environmental effects.

In the cement section, UTEST Testing Equipment is basically grouped in three main headings:

  • Physical and Chemical Property Tests (except strength tests)
  • Building Lime, Grout and Mud Tests
  • Strength Tests

The main area of usage of bituminous mixtures is in road construction. The title of bituminous mixtures is called Asphalt in USA. Bituminous mixtures consist of essentially two ingredients, aggregate and binder. The major difference between asphalt and concrete is that bitumen and bituminous materials are used as binder in asphalt.

Analysis and design tests of bituminous mixtures, bitumen and bituminous binders' tests, asphalt and road quality tests are provided for engineering firms and construction companies to produce, inspect and evaluate the paving materials to ensure the strength, physical and mechanical performance and durability towards safe application and use.

Bitumen is a crude oil product, generally used as a binder in flexible road construction due to various properties and advantages it has over other pavement construction materials. The term bitumen is often mistakenly used to describe asphalt.

The quality of the bitumen used in asphalt production has a direct impact on the durability of the asphalt. Several tests on different properties of bitumen are performed to check and ensure the quality for pavement construction

In the Asphalt and Bitumen section, UTEST Testing Equipment is basically grouped in three main headings:

  • Analysis of Bituminous Mixtures
  • Design and Testing of Bituminous Mixtures
  • Asphalt and Road Quality Testing
