Evaluation of the compressive strength of paver blocks with the inclusion of Mangima stone and Eggshell powder

The demands in building infrastructures many countries require a huge amount of concrete to be used. As such, the construction industry increased its requirement for aggregates and cement. However, quarrying dredging river harm environment. Also, cement production contributes carbon dioxide emissions. primary focus this study is evaluate application Mangima stone (phyllite schist) eggshell powder (ESP) as fine aggregate additives paver, respectively. Laboratory tests such sieve analysis, absorption, specific gravity, x-ray fluorescence spectroscopy, compression were performed. conventional was replaced with 100% stones added 5%, 10%, 15% ESP. samples subjected 28 days curing period. Results showed that addition ESP obtained highest density (2330 kg/m3) compressive strength (17.09 MPa) but had lowest absorption capacity (0.90%). In general, percentage increases, paver blocks increases. Therefore, incorporating significantly good material making innovative block material.
