Use of Bagasse Ash as a Concrete Additive for Road Pavement Application
LSU Digital Commons, 2019Co-Authors: Arce Gabriel, Hassan Marwa, Gutierrez Maria, Barbato MicheleAbstract:The objective of this study was to evaluate the use of sugarcane bagasse ash (SCBA) as a partial replacement of cement in concrete for Road Pavement Application. The study explored the pozzolanic activity of SCBA produced from three different processing methodologies (i.e., raw SCBA, controlled SCBA and post-processed SCBA). The experimental results revealed that SCBA produced by the controlled burning of sugarcane bagasse fiber (SBF) at 650°C and grinding (C-650), presented the maximum pozzolanic activity. However, this SCBA production process was deemed challenging for large-scale industrial Application due to low SCBA yield (i.e., 3 to 6%). On the other hand, post-processing of raw SCBA, by burning at 450°C and grinding (P-450), produced a similar pozzolanic activity to that of SCBA C-650. Moreover, since post-processing of raw SCBA produced a significantly higher SCBA yield (i.e., 85 to 90%) than that of controlled burning of SBF, SCBA P-450 was selected for further investigation in concrete mixtures. The effect of different dosages of P-450 (i.e., 20, 30, and 40% cement replacement by weight) on concrete properties was evaluated. It was determined that concrete mixtures utilizing substitutions of 10% and 20% of cement with SCBA exhibited a similar compressive strength to that of control after 90 days of curing for Class-A and Class-B concretes, respectively. At higher levels of cement replacement, the compressive strength of concrete mixtures decreased proportionally at both, 28 and 90 days of curing; yet, the relative strength gain from 28 to 90 days increased. Furthermore, at 90 days of curing, surface resistivity of SCBA admixed concrete mixtures was superior to that of control for all cases. Finally, a cost analysis showed that a 10% cement replacement with SCBA in concrete could yield a reduction of per lane-mile cost of 0.75%

Banana Fibre-Reinforcement of a Soil Stabilized with Sodium Silicate
Silicon, 2019Co-Authors: Ravindran Gobinath, Olaniyi Diran Afolayan, Saravana Karthikeyan, Murugasamu Manojkumar, Isaac I. Akinwumi, Sivaraj Gowtham, Ayyasamy ManikandanAbstract:Many unsuitable soils for construction purposes can be made suitable by using unconventional soil stabilizers. This study investigates the effects of banana fibre-reinforcement of a soil stabilized with sodium silicate on the geotechnical properties of the composite. It involved the Application of 1% sodium silicate with varying proportion (0.1, 0.2, 0.3, 0.4 and 0.5%) of banana fibre to a gravelly sand. Index properties, unconfined compression, direct shear, split-tensile and California bearing ratio (CBR) tests were determined for the stabilized soil and the reinforced soil samples. The results show that the plasticity index, unconfined compressive strength (UCS), shear strength, split-tensile strength and CBR of the specimens stabilized with sodium silicate increased with increasing percentage of banana fibre content. The Application of 0.5% banana fibre strengthened the soil - the UCS increased by 445%, shear strength by 80%, split tensile strength by 194% and the soaked CBR increased by 1083%. The banana fibre-reinforcement of the sodium silicate stabilized sandy soils made the stabilized soil become suitable for Road Pavement Application as sub-base material.

crude oil fly ash waste for Road Pavement Application
IOP Conference Series: Earth and Environmental Science, 2021Co-Authors: Mohammed DahimAbstract:This paper investigates the use of crude oil waste fly ash generated from electrical and desalination power plants in Saudi Arabia to improve the performance of asphalt flexible Pavement. Several asphalt Pavement materials were prepared to contain fly ash by-product waste of desalination and electrical power plants in Saudi Arabia. In addition, the paper proposed a new simple surface capacitance sensor for the assessment of asphalt Pavement material. The proposed device is a low cost, simple fast and portable which makes it easy to adapt for field investigation. The results obtained from testing several asphalt Pavement materials indicate the usefulness of this sensor in evaluating several critical parameters to control Pavement quality conditions. These parameters include asphalt moisture condition, the effect of waste fly ash filler additives, Pavement thickness, and detection of Pavement cracks. The electromagnetic properties of asphalt Pavement were measured using the proposed sensor in the frequency range between 100 kHz to 1000 kHz at various moisture conditions. The results show the applicability of the sensor to determine moisture and waste content in the Pavement material. In addition, the sensor could be a useful tool to detect cracks of Pavement and the thickness and crack orientation in asphalt Pavement. The results also indicate that the waste fly ash could improve Pavement properties and contribute to solve a major environmental problem in Saudi Arabia.
