Study of the Effect of Recycled Ash Wastepaper on the Mechanical Properties of green Concrete

The Waste materials need to be recycled in some method to avoid ground contamination. One of the methods to reuse such materials is to include in concrete materials. This will decrease pollution and encourage sustainable development in environment conservation. In this work ash wastepaper was partially replaced as 0%, 5%, 7% and 10% in place of cement in concrete for M-25 mix (i.e. concrete design mix of 1: 1.60 : 2.37 cement, sand and aggregate as per ASTM C 94 : 2007) with 0.48 w\c ratio was used. About 4 mixes with ash wastepaper were prepared. Strength properties were determined by compressive strength, splitting tensile strength and flexural tensile strength at (7, 14 and 28) days. From The results showed that the replacement of ash wastepaper increases the compressive strength and splitting tensile strength and flexural tensile strength by (22.129%), (4.160%) and (34.783%) respectively, at (28) days of curing when (5%) Of ash wastepaper was added by weight.
