Energy-Efficient Concrete Using Nano Silica & EPS 🧱 | Construction Revolution | The Science Spark

Void formers and Void fillers. Void formers decrease the volume of concrete, reducing weight while increasing the strength of concrete. Void fillers are designed to fill a void with Expanded Polystyrene and are left in-situ. | Civil Engineering&Architecture

Flart strikes again! But this time with a more concrete explanation. The skin like nature was never intentional but rather a hilarious and temporary result of the creation process. Acetone, a polar solvent, can dissolve polystyrene, the main component of EPS (expanded polystyrene or 'styrofoam'). This dissolution occurs due to the similar polarities between acetone and polystyrene. When acetone comes into contact with polystyrene, the polystyrene molecules disperse and break apart in the solvent
