Dear readers,
Time marches forward. ZKG International has completed the transition of its publisher from Bauverlag to Tech Science Press (TSP). Yes, this is a transforming time. We deeply recognize that the traditional cement, lime and gypsum materials sector is undergoing a profound shift from scale...
Concrete possesses a high CO2 footprint which originates from both cement and steel reinforcement. Prof. Manfred Curbach from TU Dresden/Germany proposed replacing steel with carbon fibers, meshes and rods, thus significantly reducing CO2 emission. His technology has already been applied on over 300...

Global policy and academic consensus: advancing the synergy of low-carbon development and digital transformation
The conference emphasized that the cement sector is a key focus of global low-carbon governance. Domestically, China’s stringent ultra-low emission targets for 2025 a...
Background
Chemico-activated concrete is formulated by using chemico-activated cementitious materials, instead of Portland cement, together with fine aggregates, coarse aggregates, and admixtures if necessary. The main components of the chemico-activated cementitious materials...
The gypsum board market
According to data from Global Gypsum, as of the first half of 2023, there were 435 gypsum-board factories operating in 72 countries. China and the United States are the two largest producers, accounting for roughly 22% and 25% of global capacity, respectively...
Introductory
At a 500-t-per-day cement production line at Emei Mountain Qianghua Special Cement Company, grayish-black granules have been continuously discharged from the rotary kiln, marking a milestone in sulphosilicate clinker industrialization. This clinker consists of C2S, C5S2$, ...
To ensure the construction of Cambodia’s first LNG power plant, CWCG’s engineering team has successfully overcome the extreme technical challenge of pouring ultra-low-temperature concrete in a high-heat, high-humidity coastal environment. This breakthrough has cleared a major obstacle for this...

The desulfurization–decarbonization mineralization pilot unit consists of a centralized dosing system, a CO2/SO2 absorption and mineralization module, and an online monitoring unit, with a maximum flue-gas capacity of 30 Nm3/h. By simultaneously removing SO2 and CO2 and converting CO2 into....
Steel slag (SS), a major solid by-product of the steel industry, holds significant potential for use in construction materials due to its high calcium content and latent pozzolanic activity. However, its large-scale utilization is limited by challenges such as low reactivity and poor volumetric...
Autogenous shrinkage is one of the primary factors leading to cracking in concrete structures. To enhance the efficiency of solid waste resource utilization, this study utilizes air-cooled blast furnace slag aggregates (ACBFSAs) to prepare concrete. The impact of different combinations of coarse and...
Alkali-activated slag (AAS) is regarded as a promising low-carbon alternative to Portland cement; however, the increasing scarcity of slag and the need for further sustainability improvements motivate the exploration of renewable and carbon-based additives. Biochar, as a porous and carbon-rich...
Sprayed concrete is widely used in tunnel support and structural repair, but the direct addition of conventional viscosity-modifying agents often causes pipeline blockage and competitive adsorption with polycarboxylate superplasticizers, which leads to poor workability and high rebound rates. To over...
