High-strength plastic concrete for underground diaphragm wall
The invention belongs to the technical field of plastic concrete, and particularly relates to high-strength plastic concrete for an underground diaphragm wall. The high-strength plastic concrete is prepared from the following components in parts by mass: 450 to 530 parts of water, 150 to 200 parts of cement, 675 to 770 parts of sand, 330 to 820 parts of stone, 145 to 200 parts of fly ash, 140 to 170 parts of clay, 35 to 60 parts of bentonite and 5 to 16 parts of nano copper oxide modified microcrystalline cellulose. The nano copper oxide modified microcrystalline cellulose is microcrystalline cellulose with nano copper oxide deposited on the surface. The nano copper oxide modified microcrystalline cellulose is added into the plastic concrete, so that the strength, anti-seepage performance and corrosion resistance of the plastic concrete can be greatly improved.
本发明属于塑性混凝土技术领域，具体涉及一种用于地下防渗墙的高强度塑性混凝土。以质量比计，该高强度塑性混凝土包括以下组分：水450‑530份、水泥150‑200份、砂675‑770份、石330‑820份、粉煤灰145‑200份、黏土140‑170份、膨润土35‑60份、纳米氧化铜改性微晶纤维素5‑16份；所述纳米氧化铜改性微晶纤维素为表面沉积纳米氧化铜的微晶纤维素。本发明通过在塑性混凝土中加入纳米氧化铜改性微晶纤维素，能极大的提高塑性混凝土的强度、防渗性能和耐腐蚀性能。
