Curing is arguably the most critical phase, as it directly impacts the hydration process and ultimate strength development. BS EN 12390.2 - 2000 (Testing Hardened Concrete - Scribd
The standard provides a rigorous framework for preparing concrete test specimens, such as cubes, cylinders, and prisms, from fresh concrete. These specimens are later used to determine mechanical properties like compressive and flexural strength. Primary Focus
Once the surfaces were leveled and smoothed, Elias moved the moulds to a shaded, vibration-free corner. The was strict: the cubes needed to stay in their moulds for at least 16 hours, but no more than three days, protected from the elements. He covered them with a damp cloth and plastic sheeting, tucked away like sleeping giants. Step 3: The Curing
For a ready-mix concrete supplier or a contractor on a major infrastructure project (e.g., HS2, Crossrail, or National Highways schemes): bs en 12390-2:2019
BS EN 12390-2:2019 the British and European standard that defines the procedures for making and curing concrete specimens for strength tests
Q: What is the purpose of BS EN 12390-2:2019? A: The purpose of BS EN 12390-2:2019 is to provide a comprehensive framework for testing the compressive strength of hardened concrete.
Mechanical vibration (vibrating table or poker) or manual tamping with a compacting bar. Goal: To achieve a fully dense specimen without voids. 1.3 Finishing Curing is arguably the most critical phase, as
The 2019 version replaced the older 2009 version, introducing refined procedures to reduce human error and minimize variables that could artificially lower or raise concrete strength results. Equipment Requirements
BS EN 12390-2:2019 does not work in isolation. It is part of a family:
Enhanced documentation requirements regarding the tracking of curing history. Testing and Documentation Primary Focus Once the surfaces were leveled and
: After compaction, the top surface is leveled using a float or trowel to ensure a flat, smooth surface for testing. 3. Standard Curing Requirements
Once demoulded, the specimens enter the main curing phase. This ensures hydration continues uninterrupted.
To prevent moisture loss from the exposed top surface, the moulds must be covered with a plastic sheet, steel plate, or wet burlap. They must be protected from direct sunlight, wind, and mechanical vibrations (e.g., from heavy site traffic). Demoulding
Immediately after finishing, the specimens must remain in their moulds.
Method of permanent curing (water vs. high humidity) and duration.
