摘要: Abstract Marble industries produce vast amounts of wastes, and this is detrimental to the environment. Accordingly, these waste materials require appropriate management ensure a cleaner Given that, utilisation recycled in construction desirable, owing space saved from landfill purposes reduction carbon dioxide (CO2) as well lower cost related materials. Subsequently, paper investigated effects adding marble powder (WMP) filler on strength performance mortar, with different Blaine Specific Surface (BSS) precise class resistance Artificial Cement Portland CEM I 42.5. The experimental investigation statistical analysis were carried out mortar mixes containing four types (F1, F2, F3, F4) BSS values 3860, 5640, 7620 9280 cm2/g, respectively. Substitution rates 5, 15, 25% applied. In addition, water/cement + filler ratios (W/(C + F)) or W/Ceq true new cement measured for each mix. Moreover, theoretical models (termed equivalence models), which enabled determination function used fillers substitution rate, developed. obtained results revealed that 5% by provided compressive similar control mix all filler. However, further increase reduced. both presented good agreement. It was concluded proper use partial replacement would have environmental benefits, simultaneously, feasibility stone industries.
