Foam Adhesives – the Foundation for a Safe Future in Building

Studies comparing the seismic resistance of walls built using Tytan Professional® thin-layer polyurethane mortar versus traditional mortar were conducted through a collaboration between the Opole University of Technology and Selena S.A. Their results have changed the way we think about masonry structures in earthquake-prone areas.

They focused on analyzing the behavior of masonry walls when subjected to seismic loads. Two types of walls were looked at: made of autoclaved aerated concrete (AAC) and calibrated ceramic bricks (CCB). The analyses included both regular walls and those reinforced with reinforced concrete frames, which are often used in seismic regions.

The studies used special software that allowed for detailed examination of the walls’ response to seismic loads. The analysis focused on evaluating the stresses in the walls, considering different earthquake loading scenarios. Particular attention was paid to the walls’ resistance to cracks and damage resulting from seismic loads, as well as the potential for the wall to exceed its tensile strength, which is crucial for the structure’s performance during earthquakes.

The entire research project took place in Opole in 2013, where a research team led by Professor Zbigniew Zembaty, working with experts from Selena S.A. company, used the available university resources and infrastructure to conduct detailed analyses. Here are the conclusions:

The Tytan Professional® thin-layer polyurethane mortar is characterized by exceptionally high adhesion to different types of masonry materials, including ceramic bricks and autoclaved aerated concrete (AAC) blocks. Better adhesion means that during seismic loads, the risk of detachment of the elements is significantly reduced compared to traditional mortar.

Traditional masonry mortars are usually weak in terms of tensile strength, which becomes critical under seismic loads, as they can cause cracks to form. The Tytan Professional® foam adhesive, thanks to its unique properties, shows increased tensile strength, which minimizes the risk of cracks and structural damage in the wall.

One of the key factors affecting the resistance of a structure to seismic loads is its ability to absorb and dissipate energy. The TYTAN mortar is more flexible than traditional mortars, which allows for better absorption of seismic energy and reduces the risk of structural damage.

Thanks to its homogeneity and better adhesive properties, the Tytan Professional® foam adhesive minimizes the risk of micro-cracks, which can spread in the wall under the influence of seismic vibrations. In structures made using traditional mortar, micro-cracks are weak points through which damage can spread.

The Tytan Professional® foam adhesive shows better resistance to water and frost than traditional mortars. This feature is particularly important in the context of seismic construction, as it protects the wall from degradation caused by these factors, which could weaken its structure and reduce its resistance to seismic loads.

The thin-layer polyurethane mortar also offers increased compressive strength, which is important for maintaining the structural integrity of the wall during seismic shocks. This strength provides additional protection against the crumbling and crumbling of bricks or blocks.
