摘要：
本发明涉及一种微膨胀混凝土，其技术要点是：以质量份数计，其原料包括以下组分：水泥265‑270份，水168‑173份，砂725‑730份，碎石1000‑1010份，矿粉75‑85份，粉煤灰75‑80份，聚羧酸减水剂10.00‑10.50份，UEA‑I型膨胀剂36‑38份。其无结构裂缝产生，提高混凝土结构的整体稳定性。
摘要（英）：

The invention relates to micro expansion concrete, which is mainly characterized in that the raw materials comprise the following ingredients in parts by mass: 265 to 270 parts of cement, 168 to 173 parts of water, 725 to 730 parts of sand, 1000 to 1010 parts of gravel, 75 to 85 parts of mineral powder, 75 to 80 parts of flyash, 10.00 to 10.50 parts of polycarboxylic acid water reducers and 36 to 38 parts of UEA-I type expanding agents. No structure crack is generated. The integral stability of the concrete structure is improved.
