Concrete is the most common man-made material on earth. It is often used in harsh environments, leading to the rapid deterioration of poor-quality concrete mixes. Element's concrete testing services ensure the concrete used is of consistently high quality and meets strict industry specifications and intended design life.

We offer a broad range of laboratory and on-site concrete and aggregate testing and inspection services to evaluate new materials, assess the condition of in-situ concrete, or demonstrate compliance with regulations and quality standards.

 Element operates comprehensively equipped accredited materials testing laboratories specifically devoted to the testing and analyzing fresh and hardened concrete. 

For over 20 years, we have been entrusted with testing concrete mixes such as standard grades, shotcrete, self-compacting, and high-performance modified mixes in some of the world's most iconic and complex concrete structures.

Concrete testing services 

From pre-construction review, concrete mix design/evaluation, and concrete batch plant monitoring to fresh concrete testing on-site and hardened concrete testing in the laboratory, Element support you at every stage of your project's construction. 

We provide a wide range of concrete testing services in accordance with internationally recognized BS, EN, and ASTM standards:

  • Full trial mix facilities with Ordinary Portland Cement (OPC) experience, rapid hardening, sulfate-resisting, Ground Granulated Blast-furnace Slag (GGBS), fly ash, and silica fume mixes with accelerating admixtures, retarding admixtures, water-reducing admixtures, and superplasticizers.
  • Fresh concrete workability testing, including slump test, compacting factor, and flow table test. 
  • Fresh concrete properties: bleed test, density, yield, cement content, and water/cement ratio analysis, temperature, and air content.
  • Hardened concrete properties covering static modulus of elasticity and poission's ratio, cylinder, core, and cube compressive strength tests, flexural strength, tensile splitting strength, creep, alkali-silica petrographic, and SCRF flexural tensile strength Limit of Proportionality (LOP).
  • Hardened concrete durability including chloride migration (NTB 492), Rapid Chloride Permeability (RCPT), water penetration and Initial Surface Absorption (ISAT), density, water absorption, Alkali reactivity (mortar bar method), and drying shrinkage.
  • Hardened concrete analysis covering cement and aggregate content, aggregate grading, original water content, type of cement, type of aggregate, chloride, and sulfate content

Our engaged experts have unrivaled experience and expertise in enacting design trial mix and quality control testing programs that ensure  the compressive strength of concrete and durability criteria is maintained.

Evaluating concrete in existing structures

Element offers cost-effective and reliable destructive and non-destructive testing solutions to assess existing structures' structural and durability performance.

Our solutions can be used to determine strength, carry out comparative quality surveys, examine localized integrity, assess potential durability, identify causes of deterioration, and select the as-built details of materials and structural components. Techniques available include:

  • In-situ strength includes structural load testing, pull-out, and pull-off testing, and static load testing of bridge structures.
  • Comparative quality testing carried out with rebound hammer (also known as Schmidt Hammer test), Building Research Establishment (BRE) screed tester, and Pulse Velocity – PUNDIT.
  • Condition Assessments covering cover measurement, crack width and depth measurement, depth of carbonation, half-cell corrosion mapping, electrical resistivity, surface absorption, in-situ ISAT, and chloride penetration profiling.
  • Supporting laboratory testing includes chloride migration by RCPT and Nordtest, water absorption, chloride and sulfate content, and determination of original cement content.
