摘要：
A light-weight high-strength plastic concrete is obtained by mixing a nonionic surface active agent having a hydrophilic-lipophilic balance of 3 to 6, a vinyl monomer, and a cement slurry with stirring to form a W/O type emulsion, thereafter polymerizing the vinyl monomer and hardening the cement in the W/O type emulsion simultaneously.The plastic concrete obtained by the aforesaid process has a smooth surface and the appearance thereof is almost same as that of an ordinary cement concrete. The plastic concrete is also excellent in workability such as cutting, scraping riveting, etc.
