Abstract: The multi-blade concrete cutting saw cuts blocks of concrete or aerated concrete into equal sized slates with one pass through the saw. The cutting saw is supported by a frame having a base, an upper support structure and a pair of guide rails. A conveyor track transports the concrete blocks through the cutting saw. A concrete block is forced along the conveyor track and passes through six equally spaced, diamond tipped cutting blades. Each of the resultant slates have equal dimensions and weight. The cutting blades are disposed along a drive shaft and are arranged across the width of the conveyor track. The cutting blades are driven in a counterclockwise direction by a drive belt that connects the drive shaft to a motor. The conveyor track may be automatically driven by a pair of belt drives.

Abstract: A lightweight roofing slate that is resistant to the pressure of high forced winds. The roofing slate is preferably made from autoclaved aerated concrete that is lightweight, fireproof, termite proof and can withstand hurricane force winds when properly mounted to a roof. Roofing slates are applied to the roof in an overlapping formation. An adhesive material is applied to the bottom surface of each roofing slate so that the overlapping roofing slate is secured to the top surface of the adjacent roofing slate and each roofing slate is further secured to the roof. A nontoxic, water based sealer is applied to the top surface of the roofing slates after they are secured to the roof.
