Optimization of sustainable concrete characteristics incorporating palm oil clinker and nano-palm oil fuel ash using response surface methodology

Powder Technology

The production of concrete by replacing cement and aggregates with biomass materials is a low-carbon footprint and low-cost approach. In this study, the influences of nano-palm oil fuel ash (NPOFA) and palm oil clinker (POC) partially replaced instead of cement (0, 15% and 30%) and coarse aggregate (0, 50%, 100%) into sustainable concrete on workability and compressive strength are investigated using response surface methodology (RSM) methods. The RSM forecasting has presented satisfactory outcomes in optimizing the quantity of POC and NPOFA in the production of concrete with acceptable strength. The peak compressive strength is achieved for the mixture containing 0% POC and 15% NPOFA, and the mixture containing 100% POC and 30% NPOFA has the lowest compressive strength. The optimum condition is successfully predicted using RSM. The use of NPOFA binder enhances the workability and compressive strength of concrete material, in addition to enhancing the sustainability of the concrete industry. Meanwhile, the results of economic and environmental assessments also show that the addition of NPOFA and POC significantly reduces the cost and carbon emissions of concrete, and the effect of NPOFA is even more pronounced. This method might result in the noteworthy consumption of POC and NPOFA in the production of concrete and assist in achieving environmental sustainability by reducing the agricultural and industrial waste by-products.

Hybrid Steel Fiber of Rigid Pavements: A 3D Finite Element and Parametric Analysis

Coatings (Issue: 10 , 1478) (Volume: 12)

Rigid pavements have high compressive strength and low flexural strength due to the brittleness of concrete. This leads to the formation of cracks easily under the applied loads of vehicles; therefore, the design of concrete pavements usually leads to an increase in the high thicknesses. Hybrid steel fibers are used in concrete to increase flexural strength and minimize crack formation. Using concrete with steel fibers in pavements reduces the required concrete thickness. In recent decades, the application of the finite element method to predict the behavior of rigid pavements has increased. This study investigates the influence of hybrid steel fiber on the behavior of rigid pavements; a finite element modeling approach is used to simulate the case study. Several parameters are entered and investigated in this study, including the proportion mix of hybrid fiber concrete (HFC), which contains 0.2% macro synthetic fibers and 0.68, 0.8, and 0.96% of steel fibers, compressive strengths of 25, 35, and 45 MPa, slab thicknesses of 150, 200, and 250 mm, and the load of the tandem axle at the edge of mid slab on the Winkler foundation. The ATENA software package is used to perform a nonlinear finite element analysis. Thirty-six rigid specimen pavements with dimensions of 3600 × 3600 mm were modeled in this investigation. The results showed that the addition ratio (0.68 + 0.2)% of hybrid fibers is more effective in improving the load bearing capacity with a slab thickness of 150 mm and 25 MPa compressive strength.

3D FE modeling and parametric analysis of steel fiber reinforced concrete haunched beams

Advances in Concrete Construction (Issue: 1) (Volume: 13)

This paper investigates the shear behavior of reinforced concrete haunched beams (RCHBs) without stirrups. The research objective is to study the effectiveness of the ideal steel fiber (SF) ratio, which is used to resist shear strength, besides the influence of main steel reinforcement, compressive strength, and inclination angles of the haunched beam. The modeling and analysis were carried out by Finite Element Method (FE) based on a software package, called Atena-GiD 3D. The program of this study comprises two-part. One of them consists of nine results of experimental SF RCHBs which are used to identify the accuracy of FE models. The other part comprises 81 FE models, which are divided into three groups. Each group differed from another group by the area of main steel reinforcement (As) which are 226, 339, and 509 mm2. The other parameters which are considered in each group in the same quantities to study the effectiveness of them, were steel fiber volumetric ratios (0.0, 0.5, and 1.0)%, compressive strength (20.0, 40.0, 60.0) MPa, and the inclination angle of haunched beam (0.0,10.0, and 15.0). Moreover, the parametric analysis was carried out on SF RCHBs to clarify the effectiveness of each parameter on the mechanical behavior of SF RCHBs. The results show that the correlation coefficient (R2) between shear load capacities of FE proposed models and shear load capacities of experimental SF RCHBs is 0.9793, while the effective inclination angle of the haunched beam is 10 which contributes to resisting shear strength, besides the ideal ratio of steel fibers is 1% when the compressive strength of SF RCHBs is more than 20 MPa.

Comprehensive Shear and Flexural Study: Experimental and FE Modeling of RC Haunched Beams Rehabilitated by Basalt Fabric

Iranian Journal of Science and Technology, Transactions of Civil Engineering

This research explores the behavior of reinforced concrete haunched beams (RCHBs) rehabilitated by basalt fiber fabric (BFF). The investigation comprises two sections. The initial segment is related to an exploratory program including two gatherings of RCHBs. Both the primary gathering and subsequent gathering have six samples. However, the former is intended to fail in shear while the latter is intended to fail in a flexural mode. The subsequent section concerns the finite element (FE) modeling of rehabilitating the damaged haunched beams. The modeling and analyses are carried out via FE software, with a new methodology of analysis to determine all of the possible load capacity of RCHBs. Two cases are considered in FE analyses for the technique. In the primary case, the analyses of undamaged RCHBs, which were strengthened by BFF, are performed to represent the upper limit regarding the …

Experimental investigation of rehabilitated RC haunched beams via CFRP with 3D-FE modeling analysis

Engineering Structures (Volume: 196 (2019) 109301)

This paper investigates the behavior of damaged Reinforced Concrete Haunched Beams (RCHBs) rehabilitated by Carbon Fiber Reinforced Polymer (CFRP) strips. The study consists of two parts. In the first part, a comprehensive experimental study was carried out on ten RCHBs and two control beams (prismatic) which were designed to fail in shear. The second part concerns with the finite element (FE) modeling of rehabilitated RCHBs. A novel finite element based approach is proposed to form a limit zone that exhibits all possible load capacities of rehabilitated RCHBs. Lower and upper intervals of this zone are determined by the maximum and minimum limits of load capacities of rehabilitated RCHBs. FE modeling of undamaged and strengthened haunched beams by CFRP represents the maximum limit, while FE modeling of the damaged beams rehabilitated by CFRP only without crack repair by epoxy represents the minimum limit. Experimental results show that shear load capacity of RCHBs rehabilitated with CFRP strips increases as compared to the capacity of them before rehabilitation. The amount of increase varies with respect to the type of RCHBs and the rehabilitation strategy. The nonlinear FE models show a good agreement with test results (R2=0.8349) where load-deflection curves of all experimentally rehabilitated RCHBs lie between maximum and minimum limits of FE analysis. Furthermore, there is a very good correlation between load capacity of rehabilitated RCHBs and the capacity of undamaged and strengthened RCHBs which is obtained from maximum limit of FE analysis results (R2=0.859).

Rehabilitation of normal and self-compacted steel fiber reinforced concrete corbels via basalt fiber

Advances in Concrete Construction (Volume: Vol. 6, No. 5 (2018) 423-463)

This paper investigates the behavior of normal and self-compacted steel fiber reinforced concrete (SCC-SFRC) corbels rehabilitated by Basalt Fiber Mesh (BFM) and Basalt Fiber Fabric (BFF) for the first time in literature. The research objective is to study the effectiveness of BFM and BFF in the rehabilitation of damaged reinforced concrete corbels with and without epoxy injection. The experimental program includes two types of concrete: normal concrete, and self-compacted concrete. For normal concrete, 12 corbels were rehabilitated by BFM without injection epoxy in cracks, with two values of compressive strength, three ratios of steel fiber (SF), and two values of shear span. For self-compacted concrete, 48 corbels were rehabilitated with different parameters where 12 corbels were rehabilitated by BFM with and without epoxy injection, 18 heated corbels with three different high-temperature level were rehabilitated by repairing cracks only by epoxy injection, and 18 heated corbels with three different high-temperature level were rehabilitated by repairing cracks by epoxy and wrapping by BFF. All 48 corbels have two values of compressive strength, three values volumetric ratios of SF, and two values of the shear span. Test results indicate that RC corbels rehabilitated by BFM only without injection did not show any increase in the ultimate load capacity. Moreover, For RC corbels that were repaired by epoxy without basalt wrapping, the ultimate load capacities showed an increase depending on the mode of failure of corbels before the rehabilitation. However, the rehabilitation with only crack repairing by epoxy injection is more effective on medium strength corbels as compared to high strength ones. Finally, it can be concluded that use of BFF is an effective and powerful technique for the strengthening of damaged RC corbels.
