Mechanism of Mega Mesh – Concrete interaction
Removal of the bleed water in concrete basically cause plastic shrinkage cracking. As the bleed water moves to the surface of the concrete tiny capillary channels develop as microscopic cracks in the concrete. Additional microscopic cracks develop and soon they meet, join, and develop into large macro-cracks. Similar cracks are being formed throughout the concrete and eventually these macro-cracks will grow together into distinct shrinkage cracks.
When the tiny macro-crack is intersected by a fibre it is prevented from further growth, and remains in its initial small size. Somewhere adjacent to the first crack another macro-crack develops and is also prevented from becoming larger when it meets a fibre. In this way the tiny macro-cracks are not allowed to develop into harmful cracks which would reduce the quality of the concrete.
- No UNLOAD & HANDLING PROBLEM – machinery, labor
- No EXTERNAL STORAGE – corrode, wide area, security
- No REINFORCEMENT PLACEMENT MISTAKE – layer, size, lapping
- No PROBLEM WHEN DISCHARGE CONCRETE – compaction, deformation, machinery
