Abstract Concrete is made with various industrial byproducts, and to check the effectiveness of concrete constituents waste marble powder, Artificial neural network, Random Forest, Support vector machines, Adaptive neuro-fuzzy inference systems models were created. Six parameters used predict compressive strength: cement, fine coarse aggregate, water-to-cement ratio, curing days. The outcomes d...

Abstract Marble dust powder is a by product of the marble industry, which produces it. Environmental contamination occurs when thrown away. Concrete using MDP was tested for strength after it mixed in as cement substitute to see how well held up. It possible replace up 10% concrete with and still have same degree strength. Higher amounts replacement (20%, 30%, 40%, 50%) result lower compressive...

Priorities for the exploration of Mars involve identification and observation biosignatures that indicate existence life on planet. The atmosphere composition sediments suggest suitability anaerobic chemolithotrophic metabolism. Carbonates are often considered as morphological biosignatures, such stromatolites, but have not been potential electron acceptors. Within present study, hydrogenotroph...

The main aim of this work is to manufacture a composite material based on natural (marble) with acceptable mechanical properties and fire resistance, for being used in habitat industry as floor or wall buildings. Marble raw the waste powder quarry plate manufacturing. To achieve objective, polyester matrix composites 50 wt.% marble 3 glass fiber (short mesh) were prepared. novelty study high pe...
