Wet mixture mortar capable of pumping

Abstract

The invention relates to pumping wet mixture mortar, which is characterized in that the pumping wet mixture mortar mainly comprises cement, fly ash, slag micropowder, yellow sand, mortar thickening powder, a mortar retarder, a mortar water reducer and cellulose ether. The application of the pumping wet mixture mortar has the advantages of saving energy and improving efficiency, protecting environment and reducing emission, fully utilizing waste such as fly ash, slag and the like from steel mills and power plants, benefiting the nation and people, simultaneously improving working efficiency, lowering labor cost, reducing labor intensity of a worker and saving machine expense.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a pumpable wet-mixed mortar. Background technique [0002] my country's urban air pollution monitoring research shows that in recent years, urban air pollution has shifted from coal smoke pollution to dust pollution. In particular, the content of suspended particulate matter in the atmosphere is increasing day by day. and related dust. If the construction site adopts ready-mixed mortar and ready-mixed concrete, it can prevent the dust "running, popping, dripping, leaking" and other pollution caused by the transportation of powdery materials such as cement, yellow sand, and stones to the construction site; it can reduce on-site mixing Secondary dust pollution caused by stacking powdery building materials in the open air; avoiding the noise disturbance of on-site mixers; preventing the waste of a large amount of cement, yellow sand and other building materials in the r...

Problems solved by technology

This will cause the mortar glue prepared from the lower layer of material to be viscous and have better performance, while the mortar prepared from the upper layer of material is looser and has poorer performance.

In this case, if manual transportation is acceptable, if pumping is required, due to the consistency of the mortar being large or small, the performance is unstable, and the pump will often be blocked.

The general wet-mixed mortar, due to one-time mixing, has a large amount, and must be stored in the mortar pool on site, and the mortar is used for a long time, often resulting in mortar sedimentation, water loss, and a large loss of consistency. Blocking the pump

Therefore, the plastering mortar and floor mortar required for many high-rise, small high-rise or underground projects cannot meet the pumping requirements of the mortar pump due to the performance of the mortar, causing the pump to block or fail to pump, which delays the construction period and wastes materials. Engineering plastering mortar is still handled manually, and transported by mechanical equipment
