Tunnel concrete comprises 0.5-1 part by mass of acrylic acid and 0.1-0.15 part by mass of styrene besides conventional components of concrete. The acrylic acid and the styrene are adopted, the acrylicacid can be in network connection after being sprayed, concrete strength can be improved while rapid coagulation is achieved, and styrene is mainly used for strengthening compounding of some internalorganic substances and inorganic substances and strengthening the structure of styrene.
一种隧道用混凝土，除了混凝土常规组份外，还包括丙烯酸和苯乙烯，所述丙烯酸的质量份数为0.5‑1份；所述苯乙烯的质量份数为0.1‑0.15份。本申请采用丙烯酸和苯乙烯，丙烯酸在喷射之后可以呈现出网络连接，能够快速凝结的同时，提高混凝土强度，而苯乙烯主要是为了加强内部一些有机物质与无机物质的复合，加强自身结构。
