Comparative Behavioural Investigation on Use of Fibers of Basalt and Bamboo in Cement Concrete Pavements
摘要
Current comparative study was undertaken for determining among the two fibers as additive at dosage levels of 0–2.0% by weight of cement for being suitable for utilization in cement concrete pavement construction and curing for specimens was carried out for duration of 7, 28, and 90 days. The results for compressive strength test in case of basalt fibers (BF) were maximum at dosage of 1.5% with increase of 10% at 28 days curing and incase of bamboo fibers (BM) it was maximum at dosage of 1.5% at curing age of 28 days with respect to control mix. While the flexural strength testing at curing age of 28 days resulted an increase of 7.25% with respect to in case of BF and for BM the increase at curing age of 28 days was 89.63% with respect to control mix. Meanwhile the results for split tensile strength were in symmetry with flexural strength test, the maximum increase at curing age of 28 days for BF was 12.91%, and for BM at 28 days of curing was 90.04% at dosage of 1.5% for BF and BM fibers. The tests for Ultrasonic Pulse Velocity tests demonstrated presence of more homogenous structure in BF specimen relative specimen containing BM. The abrasion resistance test was executed on samples with curing ages of 28 days and 90 days, the resulted produced almost same abrasion resistance values, with resistance of BF (3015.7 mm3, 28 days) being on the higher side by 1.7% relative to BM (2988.3 mm3, 28 days).
