Abstract:

A study was conducted to investigate the characteristics of concrete mixed with Mangima stone as alternative aggregates. Several design mixtures were evaluated to compare the test findings. The quality tests of the Mangima aggregates included the following: abrasion test, unit weight (kg.cu.m), specific gravity (SSD), absorption test and sieve analysis (gradation test). Concrete specimen samples were tested for compression tests. The study concluded that the Mangima stone can be a suitable alternative material for coarse aggregates to produce structural concrete because results showed that compressive strength of the concrete blended with Mangima aggregates attained higher strength capacity than the conventional (basalt) aggregates.
