“…It has been reported that introduction of ceramic waste aggregate refines concrete pore structure and strengthen aggregate/cement paste bonding (Medina et al, 2012) and this is obviously the explanation for improved strength of RCT concrete. Moreover, there is a relationship between concrete strength and aggregate's shape, size and surface (Mkpaidem et. al, 2022).…”

At present, the large quantity of wastes generated by the ceramic industry is not reused in any significant quantity. Research has shown the feasibility of incorporating these wastes into concrete production. This will benefit both the ceramic and concrete industries. However, not much research data is available on the use of ceramic wastes as fine aggregate material compared to their use as coarse aggregate material. Moreover, there are presently no models for predicting the properties of ceramic waste aggregate concretes. In this study, a modified regression theory based on Taylor’s series was adopted to formulate mathematical model for predicting compressive strength of concrete into which Recycled Ceramic Tile (RCT) is incorporated as fine aggregate. Preliminary tests on RCT indicate that it is a suitable fine aggregate material for concrete production. It has also been established that addition of RCT improves compressive strength of concrete and reduces concrete’s workability. The formulated model is a function of the mix proportions of its constituents and its predicted responses are in good agreement with experimentally observed data. The model has been tested using student’s t-test and analysis of variance and has been confirmed to be adequate and hence is validated.

“…There was a significant influence from the coarse aggregate source on the compressive strength of various nominal mixed concrete plans (Prajapati, 2019). The compressive strength increases with increasing coarse aggregate size (Mkpaidem, 2022;Ogundipe, 2018).…”

In current construction, there are still areas that utilize natural materials such as aggregates from rivers as construction materials, one of which is in the Dumoga, Bolaang Mongondow, North Sulawesi. The communities in this area still use natural aggregates from the river in the concrete mixture in the development process. The purpose of this study was to provide information to the public about the material characteristics and quality of concrete using coarse and fine aggregates from the Ongkak River, Dumoga. Therefore, this research aims to compare the results of concrete compressive strength of several mixtures in the field (1: 1.5: 2.5) (1: 2 : 3) (1 : 2.5: 3.5) (1 : 3 : 3) and (1 : 3: 4). Based on the results of the compressive strength, the optimal compressive strength value on average at 28 days is in the specimens with mixed variations (1: 1.5: 2.5) is 24.178 MPa, followed by mix (1: 2.5: 3,5) of 17.094 MPa, mixture (1: 2 : 3) of 15.459 MPa, mix (1 : 3: 4) of 13.737 MPa, and mix (1 : 3 : 3) of 12.250 MPa respectively.

“…The quality of RCC is significantly influenced by the mechanical and physiochemical properties of cement, aggregate, water, and reinforcement, which significantly impact the quality of fresh and hardened concrete [5]. The grading of coarse aggregate strongly impacts concrete strength [6] and workability [7]; well-graded aggregate preserves workability better, while poorly-graded aggregate causes bond loss and segregation. The particle shape of the aggregate promotes stronger interlocking, which strengthens and prolongs the life of the concrete.…”

Reinforced cement concrete (RCC) is the most extensively used construction material in construction industries. The concrete consumption rate every year is about 3 tons per person [1]. By 2050, concrete production is expected to rise by 2.5% annually to 4.4 billion tonnes [2]. The quality of RCC construction is influenced by factors like ingredient quality, production techniques, strength, durability, workability, and homogeneity. *Author for correspondence This requires comprehensive and inclusive perception as per Indian standards (IS 456:2000). The quality of finished RCC construction is assessed through various non-destructive testing (NDT).In contrast, the quality of constituent materials [3] is evaluated through associated destructive testing or laboratory-based investigations. A comprehensive quality assessment of RCC construction is crucial for sustainability and assessing the effect of deviations in concrete ingredients and overall quality and the associated impact on service life and sustainability [4]. Quality consideration of RCC construction can
