“…TCFST columns can obtain a first-level fire-resistance rating by using an appropriate thickness of the fire protection layer [4], [5]. Experimental verifications that test the specimens into extremely nonlinear areas show that element model analysis may properly forecast the buckling consequences [6], [7]. As the number of steel strips grows, so does the restraining effect of steel strips, the energy dissipation capacity, and the plastic deformation performance of specimens [8], [9].…”

Persistence of research was towards the behaviour of folded plate. In this project, we used GGBS blended ferrocement concrete to cover a folded plate 600 mm x 1800 mm x 150 mm. Ferro cement is a building material that is emerging as an alternative for traditional RCC. According to prior research, folded plates are the most cost-effective and visually acceptable option for longer span roofs. First, we built the folded plate model in ANSYS and investigated its behaviour in terms of load versus deflection. Later, for experimental purposes, we cast a folded plate coated with GGBS mixed ferrocement concrete. The results of the experimental inquiry demonstrate that there was an improvement in flexural behaviour when compared to the traditional model. The same was verified using ANSYS findings. ANSYS analysis aids in comparing and summarising experimental data. Both the analytical and experimental inquiry results show that ferro cement structures are a good alternative to RCC since they are less costly and lighter. Because folded plates retain their effectiveness for a longer length of time when Ferro cement is utilised. Ferro cement has made the components smaller to support the load because ferro cement parts are high in stress when reinforcement is spread.

“…Iron ore tailings is one of the mine wastes which is available in India. To minimize the negative impact of IOT on environment and low-cost construction, this can be utilized in concrete production as substitute of fine aggregate [1][2][3][4][5]. The viability of the tailings of iron ore as a substitute material on behalf of FA in the concrete for construction of concrete pavements.…”

The aim of this research is to test the characteristics of concrete by substitute fine aggregate with iron ore tailings and partial glass powder as in the place of cement. Concrete with waste products such as glass powder and iron ore tailings offer technical, economic and environmental advantages. In this experimental investigation, glass powder is replaced with cement by 10%, 20% and 30% and iron ore tailings with fine aggregates by 30% which is the optimum percentage. To study the role of glass powder and iron ore tailings combination in concrete. The properties such compressive strength, flexural strength, tensile strength and also durability parameters likely water absorption investigation for M40 concrete is carried out with different percentages of glass powder by keeping the iron ore tailings percentage constant. At 30% glass powder substitution as cement and sand with IOT increases concrete effectiveness. The concrete with 10% glass powder & 30% iron ore tailings showed a higher strength compared to the conventional mix for 28 days. Concrete mix containing 10% GP and 30% IOT showed higher flexural strength of 5.05 MPa for 28 days. Splitting tensile strength value is also increasing i. e for 10% glass powder and 30% IOT, obtained splitting tensile strength was 4.48 MPa and modulus of elasticity value was has also increased. Water absorption experiment consequences results that water absorption decreases with an increase in GP percentage. The concrete workability tends to decrease when with glass powder content increase. Concrete containing 10% glass powder and 30% IOT showed maximum strength and it is considered as the optimum dosage.
