Lhoist North America and Martin Marietta Materials have agreed a definitive merger that will combine Lhoist’s lime and limestone operations with Martin Marietta’s aggregates and heavy building materials portfolio into a single North American minerals group. The deal brings together Lhoist’s industrial lime plants and kiln assets with Martin Marietta’s quarry network and rail-linked distribution terminals, creating a larger integrated platform for construction aggregates, chemical-grade limestone and lime products. For geotechnical and civil contractors, the combined entity is likely to influence regional pricing and availability of aggregates, armourstone and stabilisation lime on major infrastructure and mining projects.

VEGAPULS non-contact radar level sensors have replaced traditional silo weighing systems at Sto’s building materials plant to monitor raw material and finished product stocks in real time. Each silo is now fitted with a VEGAPULS unit mounted on the roof, providing continuous level measurement unaffected by dust, material build-up or varying bulk densities that previously distorted load-cell readings. The upgrade is aimed at tightening inventory control and supporting punctual deliveries of cementitious and other construction materials to infrastructure projects.

Paebbl has launched Rebond 300, a near‑white, carbon negative cement alternative with a footprint of -149kg CO2 per tonne that can replace up to 30% of conventional cement in standard mixes. The SCM-based binder delivers up to 40% reduction in embodied carbon at typical replacement ratios, a 10x improvement over Paebbl’s first‑generation material, while remaining compatible with existing ready‑mix and precast workflows. The Rebond Series is formulated to work across a family of silicate minerals and uses lower clinker process temperatures, reducing heat demand and permanently storing CO2.
