Acid Proof Flooring
In places like chemical laboratories and plants, storage battery buildings etc. where acids are used or manufactured, it is necessary that the floor topping should be acid-proof. Asphalt blocks, made by moulding under high pressure a mixture of inert crushed rock aggregate and an acid proof asphalt successfully meet the requirements of an acid-proof flooring. The asphalt blocks are first laid on the hard base and then acid-proof asphalt is uniformly spread over the surface of the block. Before the liquid asphalt hardens, fine sand in small quantity is uniformly spread over it and surface is finished smooth and levelled.
