Effective Measures for Mixing and Transporting Concrete
1. Spraying Concrete Transport Vehicles with Cold Water
During the summer, it is important to pour cool water on the body of concrete transport vehicles to prevent the transfer of heat from the steel tank to the concrete, which could result in an increase in concrete temperature. Before each concrete construction project, it is necessary to wet and cool down every concrete delivery vehicle with water to avoid a decrease in construction quality due to the evaporation of moisture within the concrete.
2. Ensuring Smooth and Uninterrupted Concrete Transportation
Throughout the process of concrete transportation, it is essential to maintain smooth and clear roads. The concrete should retain its uniformity during transportation and arrive at the pouring site without any layering or segregation, while still possessing the required workability in terms of slump and air content.
3. Pumping Concrete with Care
When using pumping techniques for concrete construction, it is important to wrap the pump pipes with blankets and regularly sprinkle water on their surfaces. This helps to reduce the temperature rise caused by sunlight exposure and friction between the concrete and the pipes, thus preventing a loss in concrete slump and the occurrence of pipe blockage. During concrete pouring, attention should be given to wetting the pump pipes with water and mortar. The transportation capacity of concrete transport equipment should be adapted to the setting time and pouring speed of the concrete to ensure a continuous pouring process. If the slump of the concrete transported to the construction site does not meet the required specifications, it should be returned to the mixing station or laboratory for adjustments. It is crucial not to add water on-site without proper authorization. If the concrete still does not meet the required standards, it can be utilized for temporary road repairs, among other applications.
By implementing these measures, the mixing and transportation of concrete can be carried out effectively, even during hot weather conditions. Ensuring the appropriate temperature control and workability of the concrete mixture is vital to achieve high-quality construction results.
