Performance Advantages of Permeable Concrete Pavements
Pervious concrete pavement is a type of surface paving whose internal structure consists of a skeletal framework of interconnected pores that are in communication with the external atmosphere, while simultaneously meeting the strength and durability requirements for road and paving applications.

Comprehensive Utilization of Desulfurization Gypsum
Desulfurization gypsum is a byproduct of wet flue-gas desulfurization in coal-fired power plants and is primarily generated at these facilities. With the application and promotion of comprehensive utilization technologies for desulfurization gypsum, perceptions of this material have shifted: what was once regarded as a waste discharge from power plants is now seen as a valuable resource, thereby attracting greater interest from stakeholders.

The Role of Adding Polycarboxylate Superplasticizer to Gypsum
The first-generation polycarboxylate-based high-range water-reducing admixture is a methacrylic acid/methyl methacrylate copolymer, which is synthesized via the basic polymerization of methacrylic acid and methyl methacrylate, with ester linkages connecting the main chain and side chains. The second-generation polycarboxylate-based high-range water-reducing admixture is an acrylate ether copolymer, characterized by the presence of an ether linkage between the main chain and the side chains; this type is referred to as a polycarboxylate ether high-range water-reducing admixture and is a strictly alternating copolymer, since acrylate ethers do not promote uniform polymerization.

Main Functions of Additives in Dry-Mix Mortar
Due to their limited variety and poor performance, traditional mortars are increasingly unable to meet the demands of practical engineering applications. Dry-mix mortars are being progressively promoted and adopted, and the development of admixtures for dry-mix mortars is the key technical factor in this promotion.

Three Major Advantages of Xindadi Thick-Layer Self-Leveling Cement
The use of Xindadi’s thick-layer self-leveling flooring delivers significant economic benefits: it reduces the construction schedule by 60%, enabling earlier dismantling of construction elevators, lowering rental costs, and accelerating property handover to expedite capital recovery.

Sustainable Development of Phosphogypsum in the Building Materials Industry
The ever-expanding industrial sector generates substantial quantities of industrial waste residues, such as phosphogypsum—a byproduct of the phosphate fertilizer industry—and desulfurization gypsum produced during flue-gas desulfurization at coal-fired power plants. Given their enormous volumes, if these wastes are not promptly managed, they will inevitably lead to soil erosion, encroachment on agricultural land, environmental degradation, and pollution of air and water.
