Abstract: Waste Paper Sludge Ash (WPSA) is a waste material collected from the Paper Industry. WPSA is used as cement replacement in producing mortar and was investigated on its chemical, physical and mechanical properties. Construction material with natural resources now become limited and causes of air pollution and environmental problems.
E. Mixes for Casting of Concrete . Cement used in concrete is PPC–class F with 30% fly ash. M30 design for concrete is been done as per IS 10262:2009. Cubes of 150mm * 150mm * 150mm with different proportions of 2%, 50%, 10% sludge was casted by replacement of cement by weight. The water cement
30% replacement of cement with hypo sludge in cement concrete, the properties of concrete are similar to that of conventional concrete. The hypo sludge is also used to replace cement in cement mortar [16], though it was found that compressive strength of final product was not adequate and hence it is not suggested in mortar.
ash and Steel Slag as a partial replacement for cement and sand respectively. 2. By this experimental work, the optimum replacement ratio for M20 grade concrete mix are 0% replacement of cement by Fly ash and 20% replacement of sand by Steel Slag, which gives nearly 10% more Compressive strength than results of conventional concrete of M20 mix.
1) On replacement of 5% and 10% of cement by waste paper sludge in concrete mix there is an increase in compressive strength of 0.2% and 3.3% at 7-days, 0.89% and 2.84% at 28 days is observed when compared to control mix. 2) The split tensile strength of concrete increases at 5 and 10% replacement level of cement by waste paper sludge by 1.8% and
The strength performance of concrete containing 10%–15% of steel sludge as cement replacement seemed higher than that exerted by normal concrete . Conventional concrete has some inherent drawbacks, such as low resistance towards chemical aggression [,, ]. Moisture is a primary transporter of agents of destructions into concrete, as moisture ...

Sludge (SS) and corn cob ash (CDA) are used in replacement of cement and reduce the cost of concrete production by making use of locally available materials. 1.1 SAW DUST Saw dust is a waste material from the timber industry. It is produced as timber is sawn into planks at saw mills located in virtually all major towns in the country.
Cement mortars were molded to evaluate the influence of the concrete sludge wastes on the properties of the cementitious composite. In this case, five different mixtures were prepared: a reference mortar without additives and the mortars molded with 25% cement mass replacement by limestone filler or by CSW.
