Is a batch ticket required to show constituents weights for every load of concrete according to M 157?

A batch ticket is indeed required to show the constituents' weights for every load of concrete in accordance with M 157. This requirement helps ensure that the concrete is produced consistently and maintains the specified proportions of materials. Documenting the weights of the constituents serves multiple purposes, including quality control and traceability. It allows for verification that the mix design is adhered to and facilitates the assessment of compliance with project specifications and standards. Having this information helps concrete inspectors monitor the quality of the concrete being delivered and ensures that any issues can be traced back to the originating batch should they arise.

Providing accurate weights allows for appropriate adjustments to be made in future batches if discrepancies are noted, thus enhancing the overall reliability and performance of the concrete used in construction projects.
