Upswing through expansion

Manufacturers of AAC products focus on broader product lines

Fig. 1 Filled molds in the fermentation area: the low construction height in the fermentation area improves the heat balance and results in energy savings during the fermentation process – as well as in cost reductions in the construction phase.

Fig. 2 The cutting plant is divided into three units and ensures optimal precision of the products. The turnover manipulator takes the green cake out of the mold and transfers it to the cutting car.

Fig. 3 The curing area with the autoclaves is automatically controlled to ensure optimal product quality.

Fig. 4 The prepared frame with the steel reinforcement is installed in the AAC mass directly after filling the mold. Precise positioning is of particular importance for product quality.

In difficult business times, many manufacturers of autoclaved aerated concrete (AAC) increasingly focus on expanding their product lines. In addition to business with conventional masonry blocks in many markets, there is growing demand for large-size structural components. This demand, for example, can be easily and successfully met by extending the Vario Block range of products by Masa.

Many customers who, as newcomers, have invested in recent years in the AAC market, had focused from the very start on the manufacture of large-size structural products, in addition to masonry blocks. Among this product group are high-precision units; lintels; roof, wall, and floor elements; as well as story-high interior-wall panels. The advantages of these additional products for AAC manufacturers lies essentially in item costs for these products that are clearly more advantageous than those for conventional masonry units. Clients benefit from shorter erection times (more m² per hour...
