BASF presents new concrete additives




BASF SE is presenting its broad portfolio of innovative solutions for the aerated concrete industry under its brand name of Master Builders Solutions.
MasterCast allows faster and more efficient production. The benefit to the customers is a shorter pre-curing time. In the pre-curing phase of the production, the concrete is expanding and at the same time setting. The reduction in the water content of the concrete ensures shorter setting times.
“Concrete additives from the MasterCast series for the production of autoclaved aerated concrete disperse the binder particles efficiently, allowing the water content of the fresh concrete to be significantly reduced,” said Nicoletta Zeminian, Segment Manager Manufactured Concrete at BASF. 
In addition, MasterCast improves the rheology without impairing the pore formation process. This leads to a significant reduction in the setting time with considerable time savings. By shortening the duration of the pre-curing phase, it is possible to achieve a faster turnover of the molds, leading to an overall acceleration of the manufacturing process and an increase in the productivity of the plant.
Another benefit to the customer is the cost saving, as a result of the composition of the material, which can be changed to a less expensive one. At many plants, the individual production steps have been harmonized with each other to achieve maximum efficiency, therefore the target is not always to accelerate production. In this case, the main advantage of MasterCast is the possible reduction of up to 15 percent in the cement and lime content, with no change in the pre-curing time – resulting in significant material cost savings.
