Concrete for construction engineering drainage pipeline reserved hole plugging
The invention belongs to the technical field of building materials, and particularly relates to a concrete for construction engineering drainage pipeline reserved hole plugging. The concrete for construction engineering drainage pipeline reserved hole plugging is prepared from 170-175 kg/m<3> water for mixing, 265-292 kg/m<3> cement, 669-747 kg/m<3> medium sand, 894-916 kg/m<3> fine stone, 80-128 kg/m<3> admixture, 3.4-4.8 kg/m<3> naphthene high efficiency water reducing agent, 0.2-0.4 kg/m<3> air entraining agent, 0.3-0.9 kg/m<3> microswelling agent, 0.8-0.93 kg/m<3> setting accelerator, 0.13-0.21 kg/m<3> acrylic resin, 0.24-0.36 kg/m<3> glass fiber and 0.07-0.11 kg/m<3> silicone oil. The concrete has the characteristics of vibration-free self-compaction after casting, water repellency, microswelling without shrinkage and quick setting, thereby effectively solving the problem of severe leakage of the plugged part. The concrete is simple for construction and operation, saves both time and labor, and has favorable effects.
