BHS-Sonthofen to supply six batch mixers to CEC-PowerChina and Pakistan Frontier Works’ Diamer-Basha dam site
Pakistan: BHS-Sonthofen (Tianjan) has reported the successful delivery of two of a total of six twin-shaft batch mixers to the site of CEC-PowerChina and Pakistan Frontier Works’ upcoming Diamer-Basha dam. The Chinese division of the Germany-based company is supplying four DKX 7.00 7m3/batch precast concrete mixers and two DKX 6.00 6m3/batch precast concrete mixers as part of the project. The mixers will contribute towards the 18.6Mm3 of mainly roller-compacted concrete required for the dam’s construction.
General manager Ronny Laux said “The hydraulically bound base layers required for the dam (also known as roller-compacted concrete) must withstand the heaviest of loads. Our mixers are designed to handle demanding mixing tasks. The twin-shaft batch mixers meet the highest demands for mix homogeneity and reproducibility, even with large quantities – ensuring optimum concrete quality.”

Cemex and Carbon8 Systems partner for carbon capture research
Mexico/UK: Cemex has partnered with UK-based carbon capture equipment supplier Carbon8 Systems to evaluate possible uses of the supplier’s Accelerated Carbonation Technology (ACT) in the group’s cement production. Operators can use the equipment to produce carbon-infused sustainable materials from thermal residues. Cemex says that one possible application will be in the production of supplementary cementitious materials. Under the partnership, Carbon8 Systems will evaluate a range of Cemex’s byproducts for possible use, beginning at its Rüdersdorf cement plant in Germany and Rugby cement plant in the UK. It will also evaluate the suitability of alternative lightweight aggregates produced using ACT for sale in each market.
Executive vice president sustainability, commercial, and operations development Juan Romero said "This initiative with Carbon8 Systems is another example of the work we are doing with partners across industries, academia, and startups to tap into the latest innovation and disruptive technologies to achieve our ambition of delivering net-zero CO2 concrete globally to all of our customers."
