ABSTRACT Concrete is the basic building element for modern society. Every major construction project uses concrete in one form or another. It keeps hot and protected; it allows us to get to job safely; it beautifies our homes and yards. Concrete is produced from some of the world's most scarce property and without poisonous by-product. The concrete material in industry is recycles and reclaims during the developed process. It has a higher duration compared to other products. From the proprietor to the largest city areas, concrete is playing a main role in defensive and maintaining our atmosphere. Due to increasing use of concrete and also its high cost material it is important to decrease its cost and make it durable by adding some% of waste materials in it so that it will achieve its strength. .The aim this research is make economic and ecofriendly paver block, and Reuse the waste of AAC waste. Autoclaved aerated concrete (AAC) is a lightweight cellular concrete which has been used more than 80 years. Currently however, no good recycling options for AAC from production and destruction waste exist. The quantity of AAC Waste which is produce can be used in the manufacture of autoclaved aerated concrete. Keywords: Mortar, AAC Waste, Super plasticizer, hardener, compressive strength.

INTRODUCTION
Autoclaved aerated concrete (AAC) is a light in weight, pre-cast, foam concrete building material suitable for produce concrete masonry unit like blocks. Composed of quartz sand, gypsum, lime, cement, water and aluminum powder, are used in production of AAC blocks. AAC all together provides structure, insulation, and fire, mould-resistance. Slurry of AAC is used in making blocks, wall panels, floor and roof panels, cladding panels and lintels. AAC products may be used for both internal and external structure, and may be decorated or layered with a stucco or plaster compound to protector against the elements, or covered with siding materials.
Fig-1: AAC waste paver block 1.1. AAC Waste Blocks: Autoclaved Aerated Concrete is a Lightweight, Load-bearing; durable. AAC is quite light in mass, having lesser thermal conductivity, high heat resistance, low shrinkage. AAC includes of silica sand, cement, lime, and water and development agent. To decrease the manufacture waste, new AAC block has been developed by using recycling the AAC blocks and converted them in to the powder form. AAC powder is used in replacement of sands as well as cement. The new developed AAC was conducted by replacing cement with recycled AAC in ratio of 0% to 45%.
