Steel Slag (SS) is an industrial by product get from the steel manufacturing industries .It is produced in large quantities during the steel making operation which utilize electric arc furnaces .SS can also be produced by smelting iron ore in the basic oxygen furnace. SS can be used in construction industry as an aggregate in concrete by replacing natural aggregate. Natural aggregate are becoming increasingly scare and their production shipment is more difficult. SS is used for aggregate in hot as plat surface application. The majority of the aggregate is quantity of the concrete. Replacing all or a few of the natural aggregate with the SS will leads to some environmental benefits. For this present study M25 concrete is used. The one-sided substitute of the SS will be made for changing percentages, for example 0%,10%, 20%,30%,40%,50%. From this learn the compressive strength, flexural strength and split tensile strength will be made experimentally also to find the optimal level of SS at a particular replacement of SS as natural aggregate.

“…Structural construction with in lled frames has induces more trouble with the recommended resources of lateral load [5,6]. Normally, all type of framed structures consisted of structural and nonstructural elements [7,8]. In that, masonry in lled walls are recommended as a nonstructural member for separating the rooms and living can be pro ciently used in combination with a framing system [9,10].…”

Infilled wall is a primary structure which is used in a multistorey RC-framed structure. It is not designed like structural elements, but it is subjected to structural load and response as a heavily damaged element into the building. The main problem of an infilled wall is not actively utilizing in the framed structure and it is not interacted with frame elements. The objective of research is to utilize the infilled wall in the RC-framed structure by improving its performance of behavior. Here, two different types of brick masonry like Autoclaved concrete and clay brick masonry were used as the infilled wall in an RC-framed structure. A singly bay and single storey RC framed structure was cast and tested under a 1/10th scale model by diagonal compressive loading. The specimen was subjected to static loading by a universal testing machine. Infilled wall is weak in tension, so a reinforcing band was used to improve the performance like load carrying capacity, stiffness, ductility, and energy dissipation capacity. Based on the results of the experimental study, it is found that reinforcing band with the infilled wall gives better behavior of the RC-framed structure.

With a drive for sustainable construction, various products are being introduced to promote recycling, but often their properties relation to behaviour in fire are not known. In this paper, the fire performance of crumb rubber and a plastic eco‐aggregate, called RESIN8, were assessed. Various tests, including cone calorimeter, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC), were conducted. These are supplemented by numerical calculations and the Coats–Redfern kinetic model to quantify the thermal and fire properties of these materials. Cone calorimeter tests were conducted at 35 and 50 kW m−2, while the critical heat flux (CHF) values were determined using a range of irradiance levels. Time to ignition (TTI), heat release rate (HRR), peak heat release rate (pHRR), and thermal fire hazard parameters were quantified. Both materials were classified under the high thermal fire hazard class. The peak thermal decomposition rates occurred at 365°C (single peak) for CR and at 435°C and 550°C (two peaks) for RESIN8. The calculated activation energy values were 66.7 kJ mol−1 for crumb rubber and 55.1 and 43.9 kJ mol−1 for RESIN8 in the first and second stages, respectively. These eco‐aggregates could pose a significant thermal fire hazard, in the recycling facility during and after the recycling process, as well as when stored in bulk and when incorporated in large quantities in construction systems. Further investigation is crucial for understanding the effect of incorporating these eco‐aggregates within masonry and concrete systems from a fire safety perspective.
