Germany’s Liebherr and Designwerk have developed the first fully electric concrete mixer trucks with 10- or 12-m³ drums on a five-axle chassis. The models are scheduled to premier later this year in Holcim and KIBAG fleets in Switzerland, where five-axle mixers with 40-tonne GVW are legal.

The introduction of a powdered, concrete plant-dispensed agent positions Sika as the only admixture producer to offer the two core permeability reducing technologies: hydrophilic crystalline and hydrophobic pore blocking. The hydrostatic application-geared WT-240 P is in the former category and meets ASTM C-494 Type S requirements. Its moisture activated compounds produce insoluble crystalline deposits that form within the capillary system. The crystalline formulations have the ability to reduce capillary pore size and prevent water penetration in concrete slabs or structures.
