Influence of Production Methodology on the Pozzolanic Activity of Sugarcane Bagasse Ash
MATEC Web of Conferences, 2019
Previous studies have shown the possibility of successful implementation of Sugarcane Bagasse Ash (SCBA) as a Supplementary Cementitious Material (SCM) in concrete production. However, its use has been constrained in the construction industry due to lack of a suitable largescale processing methodology of SCBA. In this study, the pozzolanic performance of SCBA produced using three different methodologies (i.e., uncontrolled burning, controlled burning, and post-processing of uncontrolled burning) was investigated. Experimental findings suggested that SCBA obtained from uncontrolled burning (raw SCBA) is not suitable for concrete application due to high carbon content. However, post-processing of raw SCBA yields a material with an adequate pozzolanic performance for concrete applications, which is comparable to SCBA produced under controlled burning conditions.
This paper presents the use of sugarcane bagasse ash (SCBA) as a pozzolanic material for producing high-strength concrete. The utilization of industrial and agricultural waste produced by industrial processes has been the focus on waste reduction. Ordinary Portland cement (OPC) is partially replaced with finely sugarcane bagasse ash. In this research physical characteristics, chemical combination (XRF test), TG-DTA were investigated and compared with cement.The concrete mixtures, in part, are replaced with 0%, 10%,15%, 20%,25% and 30% of BA respectively. In addition, the compressive strength, the flexural strength, the split tensile tests were determined. The bagasse ash was sieved through No. 600 sieve. The mix design used for making the concrete specimens was based on previous research work from literature. The water –cement ratios varied from 0.44 to 0.63. The tests were performed at 7, 28,56 and 90 days of age in order to evaluate the effects of the addition SCBA on the concrete. The test result indicate that the strength of concrete increase up to 15% SCBA replacement with cement.

Utilization of Sugarcane Bagasse Ash in Concrete
IJSRD, 2013
Utilization of industrial and agricultural waste products in the industry has been the focus of research for economic, environmental, and technical reasons. Sugar-cane bagasse is a fibrous waste-product of the sugar refining industry, along with ethanol vapour. This waste-product is already causing serious environmental pollution which calls for urgent ways of handling the waste. In this paper, Bagasse ash has been chemically and physically characterized, in order to evaluate the possibility of their use in the industry. X-ray diffractometry determination of composition and presence of crystalline material, scanning electron microscopy/EDAX examination of morphology of particles, as well as physical properties and refractoriness of bagasse ash has been studied.
Sugar cane bagasse ash as a pozzolanic material
This study aimed to verify the SCBA's potential use as a partial replacement of Portland cement. Therefore, the experiment was divided in two stages; in the first, mineralogical and chemical analyses were performed with two samples of ash, in-natura and calcined at a temperature of 600°C for 6h. After these analyzes, it was observed that the calcined ash presented a greater tendency of material in the amorphous state, which possibly made the material the most reactive. For this reason, only the calcined ash was ground for 1 and 2h. These samples were further studied in order to check the pozzolanic activity index and the compressive strength, evaluating the replacement of 10, 20 and 30% Portland cement by ground SCBA. The results showed an increase in the pozzolanic activity index only in samples of calcined and ground SCBA, showing that calcined ash must undergo a grinding process to present pozzolanic activity.
A review on strength characteristics of concrete incorporating sugarcane bagasse ash
Sustainability, Agri, Food and Environmental Research, 2021
Sugarcane bagasse ash is an offshoot of sugar factories found after burning of sugarcane bagasse which itself is found after the extraction of sugar from sugarcane. The disposal of this material causes environmental problems surrounding sugar factories. Sugarcane bagasse ash is rich in silica that can play the role of an effective pozzolana which leads to improve pozzolanic reactions resulting in better performing building materials. Light weight concrete can be prepared from low density bagasse ash. Surface reactions are improved due to its high specific surface area. Some percentage of cement is replaced with bagasse ash to determine the fresh and hardened properties of the concrete mix. Compressive strength of the concrete can be improved tremendously on later stages of addition of bagasse ash. Incorporating sugarcane bagasse ash in concrete can further alter the other various performance of concrete. Keywords—sugarcane bagasse ash, pozzolana, fresh and hardened properties.

The increase in demand and consumption of cement, scientists and researchers are searching to develop alternative binding materials that are not only ecofriendly, but equally contribute to manage the waste. The use of industrial byproduct and agricultural waste obtained through industrial procedures has focused on managing the waste and their reduction. Sugarcane bagasse ash (SCBA) being one of the agricultural waste is a fibrous waste product produced by sugar mills. During the process at Sugar mills, the Fluid from sugarcane is extracted and ash is produced by burning bagasse at high temperatures. In this research study, (SCBA) has been replaced partially in ratios of 0%, 5%, 10%, and 15% by weight of total cement in concrete mixture. Fresh and hardened concrete properties were obtained through tests which include workability test, compressive strength and tensile strength. The test result revealed that the compressive and tensile strengths of concrete increased till 5% SCBA replacement in concrete.

The sugarcane bagasse ash is used as fuel in the boilers of the Kinana sugar factory in Sudan. The field observation and qualitative study of the ash revealed that it consisted of major amounts of carbon and organic materials; this is due to the incomplete combustion of bagasse fibers in boilers. Therefore, it became necessary to recondition the samples for use as pozzolana by re-ashing it. The study of chemical composition of the ash revealed that such byproducts are likely to be pozzolanic. Comparison between chemical compositions of Kinana sugarcane bagasse ash and the pulverized coal fly ashes (ASTM C 618 1999) shows that the composition of bagasse resembles that of Class F Coal Fly Ash, as the total of alumina, silica, and ferric oxide content is about 72 %. It may, behave like Class F Fly Ash, in its engineering properties.
