Sustainable Solid Construction – Innovation Meets Responsibility

Lightweight concrete represents a clear synthesis of energy efficiency, durability and resource conservation in solid construction. Yet its market share still shows significant potential for growth. Its performance has been proven for many years, and ongoing innovations in binders, aggregates and production technologies continue to strengthen both the technical capabilities and the environmental profile of this building material. Nevertheless, this potential is still too rarely recognized – either in the perception of the material itself or in the market. This is where this presentation begins. Building on a simple conceptual model, it demonstrates why major issues must be addressed first in any construction project: raw materials, material logic and circularity. This is precisely where lightweight concrete made from natural pumice provides the right answers – with materials that require minimal energy to produce, are regionally available and remain functionally reliable. This keynote looks ahead: How can lightweight concrete gain stronger visibility within the competitive solid-construction sector? How can climate protection and market viability be combined without compromising economic efficiency or practical usability? And how can technical data be translated into real decision-making value?

“Markets for people” means that products must solve real problems – affordably, clearly and reliably. Lightweight concrete fulfils exactly these requirements: with dependable thermal and acoustic performance, consistent material quality, transparent environmental indicators and defined pathways for circular re-use. This presentation serves as an impulse and a bridge – from awareness to action. It illustrates how the industry can actively shape the market: with building materials that take responsibility.
