Always carry a water reducer with you in the car. Water reducing agent is a concrete admixture that can reduce the mixing water consumption under the condition that the slump of the mortar remains unchanged. However, when adding the superplasticizer, you must remember that there are people from the laboratory of the commercial concrete station present, otherwise the quality and strength of the mortar will not be enough, and the driver will bear the consequences of improper use of the mixed mortar sprayer.
Return to the factory to check the water level in the tank. Every time the mortar spraying machine returns to the station after the outbound task, check the amount of water in the water storage tank. The water in the water tank should be kept full at any time in case of emergency.
Check the quality of the mortar soil before leaving the factory. The quality of each mortar may vary due to different raw materials. When the mortar is loaded and leaving the site, be sure to check the slump and workability of the mortar in the tank, be careful of the early coagulation of the mortar and the stratified precipitation of the mortar, keep the mortar spraying machine correctly used, and reduce accidents.
Reduce vehicle travel time. The transportation distance of the mortar sprayer is generally within 30 kilometers in diameter. Before leaving the car, plan the route and vehicle traffic conditions to minimize the time of the vehicle on the road.
To reduce loss, unload first. If human factors or force majeure factors are encountered, which leads to the situation that the material cannot be unloaded for a long time, the concrete condition in the mortar spraying machine should be checked at any time. Once it is found that the mortar begins to condense. Unload immediately after reporting to the person in charge to prevent the entire tank from being scrapped.
