artificially manufactured aggregate and waste from industrial provides alternative way for construction industry. Utilization of aggregate from industrial waste can be alternate to the natural and artificial aggregate. For many years there is a research for the replacing the construction material, such as fine aggregate by copper slag.

increasing rates of substitution of fine natural aggregates – sand – with fine recycled aggregates from crushed concrete) were prepared and tested. 4. The results were then compared with those for a reference concrete with exactly the same composition and grading curve, but with no recycled aggregates

FPOC with 25% FL as fine aggregate replacement by weight of total fine aggregate. The tests that were conducted are slump test, compacting factor test, vebe test and compression test at curing age of 7, 14 and 28 days. The outcome of this study shows that the replacing of artificial fine aggregates has increases the strength and

25-01-2017· Nowadays it is very important to make the concrete economical. Therefore the present work has initiated to make the concrete economical by replacing the natural sand by crushed sand in the concrete. From our study it is concluded that different Crushed sand gives different results for compressive strength depending on different quarries and from study of different research paper at …

3.2.2 Natural Aggregate 12.5 mm graded crushed gravel was used as coarse aggregate having specific gravity of 2.7 and river sand of specific gravity 2.6 used as fine aggregates. 3.3 Manufacture Of GGBS Aggregate The process adopted to produce artificial aggregate is granulation. It is the process of compressing or moulding a
