“…The results implied that the compressive strength increased with increasing curing times of 7 and 28 days for all samples. A similar trend was also found in the use of ceramic waste (RBA belongs to the ceramic subgroup) as aggregate in concrete mixtures (25). Furthermore, the trend of declining values in compressive strength occurred with the addition of RBA in the concrete mixture as an OCS partial substitution.…”

This study aims to investigate the use of refractory brick (RBA) by-products as a substitute for coarse aggregate in sustainable concrete production. Concrete mixes with water-to-binder (w/c) ratios of 0.52 and 0.49 and containing 0%, 15%, 30%, and 50% RBA as a partial replacement for ordinary crushed stone (OCS) were produced. The following properties were examined in this study: workability, compressive strength, stress-time relationship, toughness index, performance criteria, and cost analysis. The test results showed that an increase in the RBA percentage in the concrete mixtures positively contributed to concrete workability. Moreover, the compressive strength and all phases in the compressive stress and time relationship decreased as the percentage of RBA in the concrete mixture increased. However, at 15%RBA, the toughness index value was comparable to that of the reference concrete, whereas based on the performance criteria, the replacement of OCS with 15%RBA for both water-cement ratios met the minimum requirements. Meanwhile, cost comparison analysis discloses that material and production costs can be reduced by approximately 51.84% and 1.5-6.5%, respectively. Based on the analysis of all the test results, 15%RBA exhibited insignificant differences in value compared with the reference concrete. Thus, the use of 15%RBA as an OCS replacement is an acceptable and viable option for producing sustainable concrete.

“…Due to rapid urbanization, the appropriate utilization of C&D waste has become very important. The demand of coarse and fine aggregate has been in an ever increasing rate, but as they are natural resources, their supply is limited [4]. On one side, there is exploitation of the *Corresponding Author Email: akshay4592@gmail.com (A. J.

There is a growing demand of suitable substitute materials of concrete ingredients especially fine and coarse aggregates in order to achieve sustainable development in the era of rapid urbanisation. Therefore, the concrete making process by utilisation of aggregates that recycled from construction and demolition (C&D) debris has emerged as a primary objective for many government agencies. Consequently, the utilisation of recycled aggregate concrete (RAC) in structural applications become essential aspect. However, RAC can be employed in structural applications only if effective stress-strain relationship is available. The stress-strain models developed for natural aggregate concrete (NAC) are not fully suitable for RAC. Hence, the selection of good model which has precise prediction capacity plays a crucial role. Moreover, the stress-strain models provide the basis for the analysis and modern design procedures especially in FEA packages. In the present study, the stress-strain models for RAC have been selected from the literature and critically reviewed in order to evaluate their predictive efficacy. The test samples in the form of measured stress-strain relations-hips derived from literature have been compared with the predictions of each selected model. Besides the comparison of measured and predicted stress-strain profiles, the output of selected models in terms of normalized toughness and ductility index was assessed. The consistency of output of models are further evaluated by employing statistical tools such as coefficient of variance and root mean square error. The outcomes of the model in the form of polynomial expression was relatively more accurate to that of other counterparts.

“…The use of HPC shall result in reduction of structure size, increases available space and also reduce the overall dead loads on the foundation of the structure. HPC can specially be used effectively for structures exposed to severe environments, because of low permeability and high resistance to various environmental factors [3,4].…”
