Figure 1 - Dependence of shrinkage of foam concrete samples with a density of 900 kg/m3 with different amounts of polystyrene foam granules: 

1 – cement + sand; 2 – the same, + 0.1% fiber; 3 – cement + 70% sand and 30% ash; 4 – cement + sand + 10% polystyrene foam + 0.1% fiber; 5 - cement + sand + 20% polystyrene foam + 0.1% fiber
