... aggregates. Fresh and hardened properties were evaluated through slump, compressive strength at 28 and 90 days, ultrasonic pulse velocity, surface resistivity, abrasion resistance, and sulfate attack tests. Results show systematic improvements in workability, mechanical properties, and durability indicators...

... – linear regression, random forest, support vector machine ( SVM ), k-nearest neighbours ( KNN ), and decision tree – on the compressive strength of concrete. With R² values between 0.2767 and 0.7440, root mean squared error values ranging from 8.4935 to 17.0477, and mean absolute error...

... performance of concrete; however, progressive abrasion significantly mitigated these effects. At 60% CTRA, compressive strength improved to 40.9 MPa, accompanied by reduced water absorption and enhanced surface resistivity. Quadratic RSM models demonstrated strong predictive capability...

... in a rise in sorptivity from 2% to 3.5%. Experimental analysis indicates that a 20% replacement of TRA and a revolution time of 20 min are optimal, resulting in a compressive strength of 50–55 MPa. Response surface analysis indicates significant effects of TRA replacement and revolution time (p...

... (Fediuk, 2016 ; Nielsen, 2002). The compressive strength, flexural strength, and tensile capacity of FRC containing fibres of 0%, 1%, 2%, and 3% volume fraction of hooks were studied, and the results revealed that FRC improves concrete load-carrying capacity, toughness, ductility, and flexural capacity...

... of 100 mm diameter and varying slenderness (H/D) ratios were drawn from cast segments at the sites after 28 days of curing, and the results in terms of compressive strength and durability characteristics were evaluated against the results of laboratory investigation. Statistical...

... is strengthened. This would indirectly reduce the carbon dioxide footprint. An attempt was made to study the effect of various concentrations of urea on the mechanical properties of concrete. Significant increases were observed in compressive strength and split tensile strength and a reduction in the water...
