material for use in the precast concrete industry.
"The material is a new-generation polycarboxylic ether-based polymer." "The electrostatic and steric properties of the polymer molecules enable the individual molecules in the cement slurry to be powerfully dispersed.
"When concrete is poured into a mold, it is conventionally heavily vibrated to expel air and achieve a high level of compaction." "The process is very noisy and can damage hearing. After compaction, the precast concrete is usually heated to 70–90 °C to accelerate hardening."
However, the use of present material--in conjunction with a new energy-saving concrete technology known as the zero-energy system--avoids the use of mechanical and thermal energy and results in high-strength and durable precast concrete. "It reduces environmental impact by significantly lowering energy use and improves the working conditions for users by lowering noise levels."
