Effect of Bagasse Ash on the Properties of Cement Stabilized Black Cotton Soil

When proximate and locally available materials to be used for road pavement construction are deficient to meet the nominal requirements of the intended flexible pavement layer; then stabilization becomes necessary. Therefore, this paper presents the results of laboratory experiments undertaken to assess the effect of sugarcane Bagasse Ash (BA) as an admixture to cement stabilized Black Cotton Soil (BCS). The Bagasse was obtained from a dump-site at Kasuwan Shanu market Bauchi and was incinerated at a controlled temperature range between 600°C and 700°C to get the BA, while the BCS was obtained along Kanawa-Jauro-Gotel road, in Yemaltu-Deba, Gombe, Nigeria. The specimens were prepared by admixing the four blends of cement stabilized BCS (using 0, 4, 6, and 8% cement) with stepped percentage of BA (0, 1, 2, 3 4, 5, and 6%) by dry weight of the BCS. The experiments carried out on both the natural and treated BCS include; Atterberg’s limits, Sieve/hydrometer analysis, Free swell, Compaction, soaked California Bearing Ratio (CBR), and Unconfined Compressive Strength (UCS) at 7, 14, and 28 days curing periods. The BCS was classified as A – 7 – 6 (68), and CH (high plasticity clay) using the American Association of State Highway and Transportation Officials (AASHTO) and Unified Soil Classification System (USCS) respectively. In addition, the soil was also categorized as High swell potential BCS under Nigerian Building and Road Research Institute (NBRRI) classification. It was found that; addition of BA to cement stabilized BCS affected their compaction characteristics, and improved both the soaked CBR, and the UCS. On the other hand, the addition of BA alone does not improve the strength properties of the natural BCS. The optimum blend was achieved with 5% BA as admixture to BCS stabilized with 8% cement, this blend gave a 7-days soaked CBR of 73% and a UCS value of 851 kN/m2 after curing for 7 days therefore, satisfied the sub-base requirements of the Nigerian Federal Ministry of Works. This study finally recommends the use of 5% BA with 8% cement for BCS stabilization for use as sub-base in flexible pavement construction.

Effects of sugarcane bagasse ash on the properties of concrete

This paper presents a detailed investigation of the effects of refined sugarcane bagasse ash (SCBA) as partial replacement for cement on the properties of fresh and hardened concrete. The study verified that SCBA shows promising results of its use as a cement replacement material (CRM). The potential of SCBA as a CRM was found because of its chemical composition, fineness and well-controlled incineration process. The availability of bagasse is also a positive indicator for the sustainable supply of SCBA as CRM. In the world, approximately 1500 Mt of sugarcane is annually produced, which yields approximately 40–45% bagasse after juice extraction in sugar mills. In this study, SCBA content was varied from 5 to 50% as partial replacement of cement. The effects of SCBA on the workability, compressive strength, splitting tensile strength and bond strength of concrete were investigated. The results showed that the addition of SCBA (5–50% content) increased the slump value of fresh concrete. The mechanical properties (compressive strength, splitting tensile strength and bond strength) of concrete made of 5–30% SCBA showed a reasonable enhancement in the results in comparison with the 100% cement concrete.

Effect of Sugarcane Bagasse Ash as Filler in Hot Mix Asphalt

Hot Mix Asphalt (HMA) is a combination of asphalt and aggregates that will give durable road surface for pavement and is widely used in Malaysia. However, due to damages caused by excessive traffic loadings, the HMA pavement normally required frequently maintenance and rehabilitation works. Therefore in recent years, research on modification of HMA has tremendously increased in highway construction field using natural sources and recycling products such as rubber, plastic, anti-stripping agents, waste materials and etc. This study was conducted to evaluate the effect of sugarcane bagasse ash (SCBA) used as filler in HMA. Experimental laboratory were done to compare the properties of normal HMA sample with modified HMA sample using SCBA. Result obtained for both sample were compared to Malaysian Public Works Department (MPWD) specification. The laboratory result reveals that SCBA are effective in increasing the Marshall stability, flow and Resilient Modulus of normal HMA. The SCBA increases Marshall stability by 0.6%, flow 4.9% and Resilient Modulus 17.4% respectively of ordinary HMA and all test and analysis parameters for asphaltic concrete of SCBA sample comply with MPWD requirements. Therefore, SCBA has potential in modifying normal HMA.

Study on the Pozzolanic Effect of Sugarcane Bagasse Ash from Taretan, Michoacán, Mexico, on a Portland Cement Mortar

Since the construction industry is responsible for 30% of the CO2 emissions, one way to reduce the impact of the construction activity is to substitute ordinary Portland cement by pozzolanic materials. The application of using agricultural waste in the production of pozzolanic material is technically feasible, due to the calcination of organic materials and leaving ashes with a fine particle size and high SiO2 content. In the present, it is discussed the pozzolanic effect of sugarcane bagasse ash (SCBA) from Taretan, Michoacán, Mexico, on the physical and mechanical properties of a portland cement mortar. Test specimens were prepared based on replacing sugarcane bagasse ash percentages of 5, 10, 15, 20 and 30 %, relative to the weight of cement. To validate the mechanical properties of the specimens, tensile, flexural and compressive strength was determine. The porosity of the mortar was determined by means of non-destructive ultrasonic testing of pulse rate and electrical resistivity. The contribution of this paper was determine the bond strength of an overlay mortar with SCBA bonded to the concrete substrate by pull-out tests. The results showed that the addition of the sugarcane bagasse ash improved the mechanical strength, adherence of the mortar to concrete, and decreases the porosity on large curing times. Hence, it is suggested the use of Portland pozzolan cement containing sugarcane bagasse ash pozzolan, with the added benefit on the use of agricultural waste.

Spectroscopic investigation on the production of clay bricks with SCBA waste

In this paper, the effect of sugarcane bagasse ash (SCBA) addition to the brick making clay has been analyzed using spectroscopic techniques. For that, mixtures of brick making clay (BMC) with sugarcane bagasse ash (SCBA) in proportions of 0–20wt.% were hydraulic uniaxially pressed and sintered at temperatures of 800–1100°C. The partial replacement of the brick making clay with SCBA was studied with chemical and mineralogical analyzes (XRF and X-ray diffraction). The quantitative estimation of minerals was made by FTIR analysis. The results of FT-IR reveal that kaolinite, quartz, and lignin are predominant, whereas, cellulose and calcite are in moderate levels. In addition, magnetite and hematite are found in trace level. The overall results reveal that the brick making clay substituted with 15wt.% of SCBA can open up a new path for the fabrication of quality bricks at low cost.

Effects of sugarcane bagasse ash (SCBA) on the strength and compressibility of cement stabilized peat

This research objective is to evaluate effectiveness of sugarcane bagasse ash (SCBA) inclusion in peat stabilization. To develop the optimal mix design, stabilized peat specimens were tested in unconfined compression. Energy Dispersive Xray (EDX) and Scanning Electron Microscope (SEM) apparatus was used to examine elemental composition and microstructure. Consolidation tests were carried out in a standard Oedometer apparatus on the obtained optimum peat-cement-bagasse (PCB) mixture. It was found that stabilized peat comprising 20% partial replacement of OPC with SCBA has the maximum UCS and discovered to be about 1.2 times greater than UCS of peatcement (PC) specimen. The UCS of optimum PCB mixture specimens increased with curing duration in water. Compared to untreated soil, SEM results for stabilized peat gave the significant pore improvement. EDX results prove that lower carbon (C) and higher calcium (Ca) fractions shows the better results of strength. There was a significant reduction of void ratio (e) for optimum PCB mixtures as compared to untreated peat. It was observed that preconsolidation pressure, σ’c were increase with curing period. Results finding shows that the stabilized peat Cα/Cc ratios were decline dramatically from untreated peat which is indicating the stabilized mixture can effectively reduce the secondary compression.
