..., V-funnel, L-box and sieve segregation tests. Based on fresh performance, 0.5% PET fibers were selected as the best content. Three mixtures (R, E 10% and 0.5% f) were exposed to temperatures of 25°C, 100°C, 200°C, 400°C and 600°C. Residual compressive and flexural strengths were determined...

... 0.25% to 1%. The mixes were tested for key properties including compressive strength, flexural strength, permeability, durability and microstructural characteristics. The performance of the GNP-enhanced mixes was then compared to that of conventional shotcrete. Findings The results showed...

... (compressive strength at 14 and 28 days) is highest when NCA content is maximal (100%), but an increasing proportion of RCA and SRCA leads to a progressive reduction in strength. Furthermore, flexural strength at 14 days increases with a higher proportion of NCA and RCA aggregates; but, at 28 days, deflection...

... of 0.45. The test was performed to find the compressive strength (CS), flexural strength (FS) and split tensile strength. Also, durability tests like rapid chloride penetration test (RCPT), acid attack, ultrasonic pulse velocity (UPV) and water permeability test were performed. Findings After 7 and 28...

... Split tensile strength Flexural strength Compressive strength SEM Concrete being most popularly used construction material in the building industry, largely impacts the environment and raises questions about its sustainability (Rajesh et al., 2016). The use of cement in concrete...

..., were prepared, whereas nano alumina content was altered by 0.3% and 0.4% by weight of cement. Fresh property of concrete was analyzed by using slump cone test, whereas hardened properties of concrete were analyzed through compression test and flexural strength test. The interaction of nano alumina...

..., four concrete mixes with 0.45, 0.48, 0.50 and 0.55 water–cement ratio having 0.5 and 1% multiwalled carbon nano tubes incorporated by weight of cement, respectively. For hardening property analysis, compressive strength was obtained by crushing cubes; flexural strength was obtained by three-point...

.... Findings At 0.48 water cement ratio and 0.5% CNT by weight of cement workability reduced by 37% and water absorption reduced by 0.04%. But compressive strength, split tensile strength and flexural strength increased by 15.38, 33.02 and 15.75%, respectively, after 30 freeze thaw cycles. Also, weight loss...

...% of steel fiber, 25% silica fume + 1.5% of steel fiber) one with SCC (35% silica fume), and other were SCC (35% Silica fume + 1% of steel fiber, 35% Silica fume + 1.5% of steel fiber). Compressive strength, flexural strength of the concrete was determined for hardened concrete for 7 and 28 days...
