This research focused on determining the influence of barite (MB) and prickly pear mucilage (MT) on the compressive strength of concrete (f’c 280 kg/cm²) for urban buildings in Cajamarca, 2025. A quantitative approach, a quasi-experimental design, and an explanatory level of analysis were employed. Four mixtures were prepared, consisting of the standard mix and mixtures incorporating 3% MB + 0.3% MT, 6% MB + 0.3% MT, and 9% MB + 0.3% MT. The results indicated that the temperature ranged from 22.50 to 23.50 °C; the slump from 3.30 to 3.80 in; and the unit weight from 2220.00 to 2275.00 kg/m³. Based on the compression tests performed at 28 days, compressive strengths of 290.64, 303.86, 336.38, and 345.53 kg/cm² were obtained for each type of concrete. The optimal combination was identified as 9% MB + 0.3% MT, as it yielded the greatest strength increase of 18.89% compared to the control concrete [CP]. Finally, it was concluded that MB + MT has a positive influence on the compressive strength [RC] of concrete intended for urban buildings, as it increased its strength and allowed it to withstand greater compressive stresses.
