CSTB Seismic Tests

MATERRUP Structural Walls and Piers: Equivalent Seismic Resistance to Conventional Cement-based Concrete !

nitiated as early as 2022, the pouring of these MATERRUP structural concrete elements marks a world first for uncalcined clay cement..

MATERRUP technology offers a unique solution for decarbonizing the cement industry, with performance matching that of conventional cements.

Seismic tests for bracing under cyclic loading were conducted on reinforced walls measuring 3m x 3m and piers measuring 1.20m x 3m in C25/30 concrete produced in situ using MCC1© clay cement.

Key Points:

👉 Same implementation processes for walls and piers as those used with conventional cement

👉 Same tools: formwork, machinery, etc.

👉 Same workability and lead times

👉No overdosing of MCC1© cement or reinforcement

With these bracing tests on wall elements subjected to increasing alternating loads, the objective of the experimental campaign is to determine the level of ductility associated with these wall elements.

This mechanical testing is part of justifying the suitability of using MCC1® clay cement-based concrete structural elements in buildings requiring seismic provisions.

Special thanks to the CSTB teams for implementing and conducting these tests.

And also our thanks to the DEMATHIEU BARD craftsmen for their participation in pouring the walls and piers under construction site conditions to ensure tests identical to those in real-world scenarios.
