An Experimental Study on Flexural Strength of Corroded-Reinforced Concrete Beam with Fly Ash

Rice husk consists of a huge amount of silica when it is burned properly, and cement can be partially replaced by rice husk ash (RHA) to make concrete. In the present experimental research, flexural strength (FS), workability, compressive strength (CS), and indirect split tensile strength (STS) of M30 grade concrete are investigated by partially replacing cement with RHA with an increment of 5%. The influence of the various percentages of RHA as a cement substitution material on the workability, CS, STS, and FS is compared with that of normal M30 grade concrete. The water-cement ratio is 0.55, which is maintained constant. The test results also concluded that the CS, STS, and FS of concrete decreased with an increase in RHA above 15%. The findings of the experimental research show that the optimum percentage of RHA was 15%, at which point the CS, STS, and FS were at their maximum, and any additional RHA addition beyond 15% causes a significant decrease in the CS, STS, and FS, and that it is recommended to replace cement with RHA in the range of 5–15% to achieve an effective and high strength of concrete.1 © 2022

An experimental study on rice husk ash concrete

Construction of steel buildings is increasing very rapidly due to its strength, flexibility, recyclable nature, longer span, no limitation in size of components and more seismic resistance capacity as compared to concrete buildings. A Pre-Engineered Building (PEB) refers to a building which is engineered at a factory as per the specifications, codes and the loads that will be acting on the structure before production of the building components and then finally assembled at site thereby reducing the completion time. The concept of PEB involves predesigning and prefabrication process. The material usage in PEB is optimized by matching the frame geometry with the bending moment diagram's shape, which reduces the overall weight of the structure. In the present study, a review on the analysis and design of PEB structure is presented. The study discusses the various components of the PEB system and provides a detailed step to model PEB structures. From the past studies, it has been found that PEB structures are up to 50% lighter due to the usage of tapered I-sections and cold formed “Z” &amp; “C” sections, approximately 35% cheaper as compared to the conventional steel structures and show reduced lateral and vertical displacements when subjected to the seismic loading and can be constructed in half the time taken for conventional steel buildings (CSB). PEB gives a better output from the architectural point of view with large clear spans &amp; flexibility in future expansion. It has also been found that construction of PEB is more sustainable, environment friendly and economical than CSB.1 © 2022

A state of art review on analysis and design of pre-engineered buildings

Industrial Flyash (IFA) is a fine powder made from non-combustible materials and a residue of carbon from incomplete combustion. Phosphogypsum (PG) is also a solid by product of phosphoric acid processing, which is employed in a variety of fertilisers and chemicals. Traditional construction material manufacturing processes destroy the earth's vital natural resources. Furthermore, IFA and PG is a solid waste, which is frequently dumped in open spaces. IFA and PG contains natural mineral which can be used as admixture in concrete. It can be used as partial replacement to the cement in the concrete up to certain limit. The experimental findings include compressive strength (CS), flexural strength (FS) and split tensile strength (STS) by partially cement replacement with Industrial IFA and PG employing 0 %, 5 %, 7.5 %, 10 %, 12.5 %, 15 %, and 20 % on M40 grade concrete and water-binder ratios of 0.45. The CS is determined by testing cube specimens for 7 and 28 days, as well as FS and STS is found by testing the beams and cylinders specimens for 7 and 28 days respectively. The optimal proportion shows maximum strength at 15 % IFA and 7.5 % PG respectively. Further increase in percentage, strength of concrete decline marginally. 10 % substitution of cement with IFA + PG (combined 50 % each) used shows the optimal proportion to achieve maximum strength, and further increase in IFA and PG causes a decrease in strength. The addition of IFA and PG increases the amount of water required due to increase in fine particles or a bigger surface area. When compared to the control mix, the workability of concrete with IFA and PG reduces slump value by up to 15 %.4 © 2022

Experimental Investigation of Scouring Around Circular Piers with Different Opening Ratios

The nano materials improve the mechanical properties of a cement concrete is a remarkable achievement in the field of nano composites. Matrix cement has a relatively loosely bonded structure which can be filled with Nano alumina which significantly improves the mechanical properties of cement. The present study discusses the development, manufacture and properties of the concrete made by nano materials. In the present study, the sulphate resistance of concrete is improved by the addition of Nano Alumina by partial replacement of cement. The study is carried out by partial replacement of cement by colloidal nano alumina- Al2O3 (CNA) particles with varying percentage (0%, 1%, 2%, 3%, 4%, and 5%) in the M55 grade of concrete. The study also evaluates an optimum dose of nano alumina at which maximum compressive strength of concrete is achieved with minimal sulphate attack observed in form of mass reduction in the concrete. It is observed that by an addition of 2.3% of CNA, the maximum sulphate resistance of concrete is achieved after 28 days. It was also observed that by an addition of 2% to 2.5% of Nano Alumina the compressive strength of concrete increases with a decrease in trend observed at 3% addition of Nano Alumina. © 2022

An Experimentation on Properties of Geo-polymer Concrete with fibres

Pune metro network is one of the major national projects in India. It aimed at developing an elevated andunderground transportation system to solve the severe traffic problems in Pune. The underground line includes 5 undergroundstations which are Shivajinagar, Civil court, Budhwar Peth, Mandai, Swargate and tunnels. The tunnel for Pune Metro Line 2 has acircular cross section of 5.8m internal diameter that consists of a precast segmental lining thickness of 0.275m. This reportpresents a parametric study on the effects of seismic waves on the tunnel structure through numerical modelling employing thefinite – element analysis. Full dynamic analyses were performed employing earthquake motion of maximum magnitude earthquakein Maharashtra which is Koyna earthquake in 1967 of 6.5 magnitude. The analysis of soil-structure interaction was done using thecommercial software Rocscience-RS2. The results proved that the 275 mm thick circular cross section can safely sustain theexpected static, dynamic and seismic stresses. This research work focuses on the behavior of Segmental lining used for the Punemetro tunnel under seismic loading. Detailed behavior of Pune metro tunnel, designing of Metro tunnel along with seismic loadingand its behavior have been studied. Finite element modelling by using software RS2 has been done for 6 cases.
