Use of Recycled Tires as Partial Replacement of Coarse Aggregate in the Production of Concrete Michelle Danko, Edgar Cano, Jose A. Pena Purdue University Calumet Abstract It is estimated that more than 270 million scraptires weighing more than 3 million tons are produced in the United States each year. This waste being non
aggregate was replaced by recycled coarse aggregate in the ratio of 0%, 25 %, 50%, 75% and by volume. The preliminary mix design was carried out for target strength of 30 MPa. After the initial mix design, the trial mixes were prepared and tested for the fresh properties of SCC as per EFNARC guidelines. The mixes were

compressive test on recycled coarse aggregates, natural aggregates and 50% natural aggregates+50% recycled coarse aggregates. This is done to see and verify the various patterns. After getting sufficient values a mix design is prepared for 0% 50% and recycled coarse aggregates. Mix design is done as per I s 10262

The recycled aggregate used was a crushed and unwashed recycled concrete aggregate, with a nominal size of 10 mm sourced from a construction and demolition waste recycling facility. The coarse natural aggregate consisted of crushed granite with a nominal size of 10 mm. Table 1 presents the water absorption (24 hours) and density of the natural and recycled coarse aggregates.
Nov 08, 2019· Corresponding to the current annual production of cement of 300 million tons, total requirement of coarse and fine aggregate for use in cement concrete, mortar and plasters of about 1500 metric tons per year is a safe estimate. There is difficulty .
It is known that the aggregates from domestic natural resources have negligible absorption, up to 1% as maximum, while the value of the classically recycled coarse aggregate typically ranges within the interval from % to 10%, and for the fine aggrega te, within the interval from % to 13% [2,7].
