Abstract

Paving slabs are made using crushed volcanic rock as aggregate, (esp. basalt) together with cement and flyash as filler to give a good plasticity. The mix. is slurried with sufficient water to make a castable mix. and cast into moulds with vibration and press. the fan of the mould being kept at the bottom. The slabs are allowed to set, demoulded, impacted with air/water spray under press. then stored in a saturated atmos in a tunnel oven. For use as tramways or foot paths the slabs have good antiskid properties esp. in rain.
