As far as possible, the landfill step has to be omitted from the mind by giving more emphasis on 100% recycling of waste. The inert waste is the result of enormous construction and demolition activities and it mainly consists of concrete, bricks, stones pebbles, and so forth.

Stencil templates are used to create visually aesthetic patterns in vertical and hori¬zontal cementitious overlay systems. Actual coverage will vary due to the porosity of the surface. The use of recycled aggregate for the production of concrete involves breaking demolished concrete into materials with specified size and quality. Integricote developed a nanotechnology-based formulation that would bind to concrete and masonry from the inside out upon application. Attention must be paid to the environmental impacts of sewage sludge ash when it is reused. Sewage sludge ash has been used as an additive in the production of construction materials [3], mortars [4], and concrete [5]. However, for the last years nearly all ash samples have been tested non-hazardous. Currently most of the ash is landfilled at considerable cost to the waste- to-energy industry. Six emission abatement options were studied and the increase of the total investment and operational cost of their use was estimated. The results show that the presence of air voids and crumb rubber particles in the matrix can increase the water absorption but decrease the thermal conductivity.

Carbonation reaction converted early hydration products to a crystalline microstructure and subsequent hydration transformed amorphous carbonates into more crystalline calcite. Egypt, in manufacturing masonry units has been investigated. Two samples of masonry units were manufactured in a small factory using crushed-fired bricks. Organic carbon leaching behavior from incinerator bottom ash. Leaching toxicity characteristics of municipal solid waste incineration bottom ash. Alkaline nature of the concrete was observed due to the change in colour of phenolphthalein. Table 3 for 20 and 10 mm sizes along with physical properties like specific gravity and bulk density. Table 3 reveal that there is a marked difference in the properties of natural and recycled coarse aggregates. Therefore the recycled aggregate may be characterized as inferior quality aggregate by being weaker than the normal aggregate [33, 34]. Improvement in density and water absorption of lower size (10 mm) recycled aggregate is more than large size (20 mm) aggregate because of presence of higher amount of adhered mortar [25, 35].

This may be due to the increased amount of hydration products on prolonged curing period.

Similar trends have also been reported by earlier workers [37]. No carbonation has been observed in concrete using natural and recycled coarse aggregates after a period of 28 days of carbon dioxide exposure.
