The main objective of this work is to evaluate the combined effect of two natural pozzolan varieties (black and red) with different grain sizes (fine powder < 65 μm and coarse aggregate) on the thermomechanical properties of lightweight concrete. Firstly, the characterization of red and black pozzolan was conducted to determine their …

This is demonstrated in Figure 3. The pozzolanic reactivity of a lightweight aggregate based on sintered fly ash such as Lytag also depends on both reactivity of the fly ash and temperature level and duration of the sintering. The firing temperature of lightweight aggregates, which is typically 1200°C, may cause recrystallization, thus ...

ESCS lightweight aggregates contain a uniformly distributed system of pores that have a size range of approximately 5 to 300μm, developed in a continuous, relatively crack-free, high-strength vitreous phase. Pores close to the surface are readily permeable and fill with water within the first few hours to a few days of exposure to moisture.
