Utilisation of iron ore tailings as aggregates in concrete

Sep 07, 2015This study seeks to add value to the tailings by utilising them as a replacement for aggregates in concrete. A concrete mix of grade 40 MPa was prepared in the laboratory with watercement ratio of 0.5. The concrete were cured for 1, 2, 3, 7, 14 and 28 days.

Strength and Durability Evaluation of Recycled Aggregate

May 14, 2015The concrete mixes had the same water to cement ratio (w/c) and cement content. Several mixes were prepared utilizing four grades, grades 1, 2, 4, and 5 of the recycled aggregate. Mixes were identified according to the grades used in each mix, for example, Mix 1,2,5 indicates that grade 1, grade 2 and grade 5 were used in that mix.
