“…C4 -application of vibropressing. This method is used, among others, for compacting concrete pavement slabs [15], paving stones [8], masonry bricks [1], etc. Based on research carried out by scientists, we can conclude that the use of vibropressing in sand-lime products has a more beneficial effect on the compressive strength of the finished product than pressing.…”

Sand-lime products are characterized by advantageous features: compressive strength, thermal accumulation and acoustic insulation. Product features are resultative choice of decisions made at individual stages of the production process: method of thickening the raw material mixture, time and temperature of autoclaving and the pressure of saturated steam. The above factors may affect on the characteristics of sand-lime products not only directly, but also through other factors. However, there is no suggestion in the literature about the relationship between these factors. The aim of this article is to find answers to the following questions: which stage of the technological process is the most important? What impact does the individual stages have on each other? Whether and to what extent modification of a given stage will affect the compressive strength of finished products? The authors carried out an analysis using the DEMATEL method to identify factors that have a key influence on autoclaved materials. The results show that using the right amount of water in the raw material mixture is the most important factor. To a slightly lesser extent, proper selection of amount of the quick lime is important. The least important factor is the method of forming silicate products. Although the time of autoclaving has a large contribution in the creation of the impact network, however it is caused by the influence of thermal and humidity conditions, the amount of lime, water and, in the low extent, the molding method.
