Solution to Concrete Pump Loss
-
Ideas and methods to solve the problem of concrete pump loss:
1. Solutions to pump loss caused by water and additives absorbed by sand aggregate
Pre-wet the aggregate to make the sand aggregate absorb water, so as to avoid water absorption during the pumping of concrete mixture and solve the problem of pump loss.
Improve the quality of concrete aggregates, avoid using aggregates with many pores and high water absorption, especially avoid using aggregates with large silt content and flocculants. Optimize aggregate grading, reduce aggregate porosity, and give priority to the use of coarse and fine aggregates with good particle shape.
Adjust the amount of admixture and the amount of slump retention agent in the formula to ensure that the admixture is added in sufficient quantity.
2. Solutions to pump loss caused by chemical reaction of cementing materials
The slump loss caused by time is compensated by adding slow-release mother liquor to the admixture to maintain the slump;
The state of the concrete mixture is maintained by adding retarder to delay the chemical reaction of the cementitious material.
Solve the problem of "undervulcanization" by adding sulfur and other means.
- Solutions to pump loss caused by operation
It is mainly to increase the pumping capacity of this high quality equipment, eliminate the gas in the concrete delivery pipeline, realize full pumping, prevent the concrete mixture from evaporation and separation of slurry and bone in the pump pipe, and solve the problem of pump damage.
- Solutions to pump damage caused by site construction and unreasonable pipe layout
It is mainly solved by reducing connecting elbows and increasing air tightness to realize continuous pumping construction.
5. Solutions to the loss of bubbles in concrete under pump pressure
It is mainly solved by selecting high-quality air-entraining agent. For example, polycarboxylic acid water reducer, it is better to select high-quality ether air entraining agent that is more suitable for polycarboxylic acid. Check out this company to find more concrete pump.
