balance. The compressive strength properties of concrete containing marble dust powder at 0%, 5%, 10%, 15%, 20% and 25% of Portland cement. The investigation was primarily to determine a resolution to the disposal problem of marble dust by making usage of it in concrete production for sustainable construction development.

Abstract. With the increasing development of oceanic resources, coral aggregate concrete has wide potentials in the construction of islands and reefs, as well …

The effects of different sea areas, coral species, particle size, and other influencing factors on the porosity and compressive strength of coral aggregate samples were discussed, respectively.

Generally, 90% strength gain is usually observed within 28 days of hydration; however, in the right environments, concrete can continue to gain strength over time. Gotti et al. (2008) determined that a replicated, Vitruvian-formulated, hydraulic concrete with a six month cure time had a compressive strength of about 670 psi.

Introduction. Around three million tons of waste marble powder (WMP) are generated by the ornamental stone industry each year [1]. The uncontrolled disposal of WMP can cause environmental problems in the surrounding ecosystems, including reducing the soil's porosity and permeability, and compromising its overall fertility [2].
