What is it we do?
Compressive Strength of Concrete Cubes (BS EN 12390)*
The cube test is the most widely used method of assessing the quality of hardened concrete.
Cube-Making: Concrete & Mortar (BS EN 12350 / BS EN 12390 / BS 4551)*
On-site monitoring of the quality of concrete and mortar during construction.
- Slump Test and Flow Table Test (BS EN 12350)*
Compression Test on Concrete Cores (BS EN 12504-1)*
This methodology is used to assess actual in-situ strength of concrete in cases of non-compliance or in old structures.
Rebound (Schmidt) Hammer Surveys (BS EN 12504-2)*
A popular technique to assess the surface hardness of concrete in an existing structure.
Building Surveys (Intrusive & Non-Intrusive)
Surveys are undertaken in older structures to assess potential defects to enable the client to plan possible repairs and assess the future working life of a structure.
Typically used in older structures to locate steel reinforcement in hardened concrete.
Depth of Carbonation, Chlorine & Sulphate Content
Techniques used to assess the risk of corrosion and degradation of steel reinforcement.
Presence of High Alumina Cement (HAC) (BRE IS15/74)
A test vital for the process of providing guidance and additional testing for structures containing HAC concrete.
Aggregate/Cement Ratio (Cement Content) (BS 1881: Part 124)
Determining the cement content to assess compliance and durability of concrete.
Mix Proportions of Mortar (BS4551)
This methodology is used to assess compliance of hardened mortar.
Compressive Strength of Bricks (BS 3921)
Testing can be carried out on both new and old bricks to ascertain compressive strength.
On-Site Concrete Cube Make Demonstration
HCT recognise that concrete test cube failures are often the result of a poor cube-make technique, or inadequate equipment or tools being used. As such, in addition to the supply of test equipment, we have developed an on-site 'Cube Training demonstration'. This 1 hour course is conducted by our experienced Concrete Field Technicians and is ideal for Site Engineers, Operatives and Managers alike to learn how to correctly sample and make a concrete test cube to British Standards. Contact us today to discuss particulars of your requirements.
