Abstract
The invention discloses concrete used for a canal lining. The concrete is prepared from the following raw materials in parts by weight: 150-183 parts of cement, 825-847 parts of sand, 1211-1243 parts of crushed stones, 50-61 parts of fly ash, 0.9 part of Danqiangsi anti-cracking, anti-leakage and anti-abrasion fiber, 2-2.44 parts of a TF delayed coagulation efficient water reducing agent and 130-134 parts of water. The invention further discloses a preparation method of the concrete used for the canal lining. The concrete has the following advantages that 1, the concrete prepared according to the concrete matching ratio has good flowability and moderate hardening speed and has a smooth surface after being pressed, and is very suitable for rapid molding large-scale construction of a lining machine.
