Influence of recycled fines on the flexural creep of self-compacting concrete beams under four-point bending load

Ultrasonic Evaluation of Cement-Based Building Materials Modified Using Marble Powder Sourced from Industrial Wastes

“…By checking the available literature related to the utilization of MP as a cement replacement in cementitious materials using the destructive tests, most of the studies concluded that the MP has the desired effect on the improvement of the selected fresh and hardened properties, and the durability of the cementitious materials [7][8][9][10]. For instance, the addition of MP in mortar matrix up to 10% of replacement ratio contributed to an improvement in the fresh properties such as the workability [8,11] and the mechanical properties such as the compressive strength of composite mortar [12,13], whereas Mohamadien [14] and Aliabdo et al [2] found this improvement to be continued up to 15% of MP replacement ratio.…”

“…This is due to the MP that features by a micro-filler effect that helps in forming a dense mix by filling the voids [13]. While the utilization of MP in self-compacting concrete as cement replacement led to decrease the UPV values [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], it was concluded that this decrease is due to the reduction of C 3 S and C 2 S in cement paste [15] which reduces the volume of hydrated products. Other studies [2,18] have shown that the utilization of MP as cement or sand replacement has an insignificant effect on the UPV values of concrete.…”
