Abstract
Air entraining concrete with superabsorbent polymers (SAP) – Part 3: robustness to fluctuations in raw materials and ambient conditions. The production of the required artificially introduced air void content in fresh concrete poses a major challenge under certain practical construction conditions. Fluctuating properties in the air void content can lead to increased rejection of deliveries as well as to poor concrete properties. The influences on air void formation and stability are manifold and result from concrete technology, production-related and environmental conditions. The robustness of superabsorbent polymers (SAP) against practical variations for the introduction of an artificial air void system into hardened concrete is still relatively unknown. Building on the previous parts 1 (fresh concrete properties) and 2 (hardened concrete properties), this article describes and discusses systematic investigations into the robustness of LP concretes with both superabsorbent polymers and classic LP formers to fluctuations in the starting materials or ambient conditions (temperature). The experimental results show that superabsorbent polymers (SAP) in concrete react very robustly to such practical construction influences with regard to the introduction of artificial air voids and the resulting frost resistance.
