Run four-point bend tests for LOP, MOR, and Young’s Modulus, fully compliant with BS 6342 and the EN 1170 series. Trusted by GRC manufacturers, precast concrete producers, and test laboratories across India and globally.
GRC (Glass Reinforced Concrete), GFRC (Glass Fiber Reinforced Concrete), and GSFRC are different names for the same material — all tested to the same standards.
What Is GRC & Why Does Testing Matter?
Glass Reinforced Concrete (GRC) is a composite of Portland cement, fine aggregate, and alkali-resistant glass fibres. It is used extensively for architectural facades, cladding panels, street furniture, drainage channels, and decorative precast elements.
GRC vs GFRC vs GSFRC
GRC is the standard British/Indian term. GFRC (Glass Fiber Reinforced Concrete) is the equivalent North American term. GSFRC is an older technical designation. All refer to the same material and are tested to the same standards — BS 6342 and EN 1170.
Why Test GRC?
GRC mechanical properties — flexural strength, tensile strength, elastic modulus — degrade as glass fibres age in the cement matrix. Regular testing verifies the material still meets specification and ensures long-term structural safety of architectural cladding and infrastructure.
Key GRC Test Parameters
Critical measurements include LOP (Limit of Proportionality — first crack), MOR (Modulus of Rupture — peak strength), Young’s Modulus, tensile strength, and impact resistance (I-value) — all measured per BS 6342 and EN 1170.

GRC Testing — Frequently Asked Questions
Common questions about GRC (Glass Reinforced Concrete) testing, standards, and equipment
GRC testing (Glass Reinforced Concrete testing) measures the mechanical performance of GRC panels and components — including flexural strength (LOP and MOR), tensile strength, elastic modulus, and impact resistance. It is required by BS 6342 and EN 1170 to verify that GRC product meets specification before use in architectural cladding, infrastructure, and structural applications.
Limit of Proportionality (LOP) is the flexural stress at the point of first crack in a GRC beam specimen. Modulus of Rupture (MOR) is the maximum flexural stress at failure. EN 1170-5 and BS 6342 require both values as primary indicators of GRC mix quality and glass fibre content. Higher MOR:LOP ratios indicate better fibre reinforcement.
All three refer to the same composite material — concrete reinforced with alkali-resistant glass fibres. GRC (Glass Reinforced Concrete) is the standard British and Indian industry term. GFRC (Glass Fiber Reinforced Concrete) is used in North America. GSFRC is an older academic/technical designation. All are tested to the same standards: BS 6342, EN 1170, and ASTM C947.
Yes. By repositioning the support spans and loading arrangement on the Testometric UTM, the same machine performs both test types for GRC specimens. Software templates automatically calculate LOP, MOR, toughness indices, and Young’s Modulus for each configuration.
GRC flat panels are cut into dog-bone or rectangular strip specimens and gripped in friction-grip or bonded-tab fixtures. Ultimate tensile strength, strain at peak load, and elastic modulus are computed per BS 6342 and EN 1170-4. This is essential for age-testing programmes monitoring fibre durability over time.
