Throughout the trials, the water-to-powder ratio (w/p) remained constant at 0.45. RHA was initially added to OPC in different ratios, from 2% to 10% by weight of cement. Finding the ideal percentage of RHA substitution that could be attained while preserving the desirable qualities was the goal. After that, a replacement range of 5% to 15% of SCBA was investigated by combining SCBA with the determined optimal RHA percentage.The Evaluation of the self-compacting concrete specimens modified with RHA and SCBA's fresh properties as well as their compressive strength characteristics were included in the inquiry. An Artificial Neural Network (ANN) model was used for deep learning in order to predict the compressive strength as the dependent variable. Decision trees and Random Forest Regressor were used for machine learning in order to compare and evaluate the accuracy of various modelling algorithms. Essentially, the goal of the study was to ascertain the ideal ratios of RHA and SCBA to OPC in order to preserve the intended characteristics of the concrete. In order to obtain precise forecasts and insights, this involved investigating new characteristics and compressive strength values. To do this, ANN, Random Forest Regressor, and Decision Tree algorithms were combined.

performance of a steel frame under cyclic loads with a
fixed base and a STRP base. Because of its effectiveness in
resisting seismic shocks, seismic base isolation technology
is thriving in industrialised countries. Scrap Tyre Rubber
Pad (STRP) bearings will be a low-cost alternative to
traditional seismic base isolation procedures for
underdeveloped countries. The qualities of STRPs are
nearly identical to those of traditional rubber bearings.
Researchers conducted numerical analytical research on
STRP bearing for buildings and proposed that it be
employed for low-rise regular buildings, yielding superior
results. In an effort to better understand how the STRPs
operate in a scaled-down steel frame structure, an
investigation has been made based on the findings of
analytical investigations. The purpose of the experiment
was to compare the steel frame's performance with and
without STRP bearings. Examining the sliding ability of
the STRPs positioned in the frame is the primary goal of
this work. The deflections of the frame at the top, middle,
and bottom stories have been evaluated for this aspect, for
the lateral seismic force applied. From the investigation, it
is observed that maximum deflections are observed at the
roof storey than other stories tested for the investigation.
Significantly, it is observed that an ultimate degradation of
stiffness of the frame of about 23% to 40% is attained and
subsequently, a superior increase in energy dissipation
capacity of about 40% is attained which is a prominent
factor required for a base isolation material.

The impact of fibre content on the structural characteristics of hybrid fibre reinforced specimens having different fibre-volume fractions will be investigated. The parameters of investigation include compressive strength, split tensile strength and flexural strength. The specimens are incorporated with 0.0 to 1% volume fraction of Steel and Polyester (Recron 3S) fibres in different proportions. The optimum percentage of hybrid fibre content is obtained. The structural behaviour of hybrid fibre reinforced concrete specimens at optimum fibre content will be compared with that of conventional concrete specimens.

In this paper an experimental program is undertaken in which three different mixes (i) Replacing 10mm, (ii) 20mm and (iii) 20mm, 10mm Recycled Coarse Aggregates (RCA) to the normal aggregates in the mix with a proportion of 20%, 25%, 30%, 35%, 40%. For each mix admixture, Glenium ACE 30 – 0.55% of cementitious material is added for attaining early strength and three cubes are casted, then compressive strength of concrete at age of 12 hours, 3 days, 7 days and 28 days are determined and the results are compared with compressive strength of conventional concrete. From the Compressive strength test results, it is observed that 40% replacement of 10 mm aggregates and also 40% replacement of 20 mm aggregates in RCA mixing attains more strength when compared to conventional mix at 28 days curing. It is also observed that, on 20% Replacement of 10 mm, 20 mm and combination of 10 mm and 20 mm in RCA mix cubes, compressive strength results are closer to the compressive strength results of conventional concrete at 12 hours, 3 days, 7 days, 28 days curing. However, Compressive strength is decreased, while replacing recycled coarse aggregates of 30% in mix at 28 days. But the earlier strength is same as conventional concrete mix.
