| description | The sustainability of the natural environment and eco-systems is of great
importance. Waste generated from construction forces mankind to find new dumping
grounds and at the same time, more natural resources are required for use as construction
materials. In order to overcome this problem, this study was conducted to investigate the
use of concrete waste in concrete blocks with a special focus on the thermal and
mechanical properties of the resulting products. Three varieties of concrete mixtures were
prepared, whereby they each contained different amounts of concrete waste of 0%, 5%
and 15%, respectively. These mixtures were formed into cube specimens and were then
analysed for data on their compressive strength, density and ultrasonic pulse. Thermal
investigations were carried out on each admixture as well as on a control concrete block
of model design. The thermal data results indicated that the 15% concrete waste
mixture had the lowest temperature in comparison to the surrounding air. For
density and compressive strength, the highest readings came from the control
mixture at 2390 kg/m3 and 40.69 N/mm2, respectively, at 28 days. In terms of pulse
velocity, the 5% concrete waste mixture indicated medium quality results of 4016 m/s. |
