“…Testing indicates that the calcium properties significantly dominate CaO compound at 93.3% where calcium oxide is a key component in the making of cement. Calcium is one of the Portland cementforming chemicals usually obtained from lime and chalk alone to fill 85% of the cement mass (Citrasari, 2019;Do et al, 2019;Kareem, 2023;Ren et al, 2020;Zhang et al, 2019). CaO oxide is the major oxide which contributed to its formation clinker and the quality of cement produced (Damdelen, 2019;Jiang et al, 2021;Ma et al, 2018;Yang et al, 2022;Yusuf et al, 2021).…”

Candlenut is a superior commodity with great opportunities. Processing of candlenut seeds produces candlenut shells which are hard with a calorific value of 4164 cal/g so can be used as fuel. Processing candlenut shells as fuel produces waste of ash and not been utilized optimally. In this research, candlenut shell ash was used as a new alternative in making paving blocks, namely to substitute sand by 13%, 18% and 25% by weight of sand. The method used to analyze the chemical content of candlenut shell ash through XRF testing and compressive strength testing with a Compression Testing Machine after 28 days of curing time. Based on the results of the XRF test, hazelnut shell ash has a CaO content of 93.3%, where CaO is the main ingredient for making cement. In addition, the results of the average compressive strength of paving blocks at 13% substitution of candlenut shell ash produced a compressive strength of 5.89 Mpa, 18% substitution of candlenut shell ash of 8.72 Mpa, and 25% substitution of candlenut shell ash of 11.07 Mpa. The results of the compressive strength of paving blocks with the substitution of hazelnut shell ash produced standard standard paving block strength of D quality.

Concrete Paving Blocks (CPBs) are generally used in pavement structures. Quite often there are differences in the test result characteristics of cube and block-shaped samples. This research aims to analyze the characteristics of differences in height by considering 60 samples from five different factories. The sample dimensions are 200 mm length and 100 mm width with varying heights of 60 mm, 80 mm, and 100 mm. The tests include water absorption, compressive strength, flexural strength, tensile splitting strength, skid resistance, and abrasion resistance. The results of the mortar content show no significant difference between the five sources. According to the findings, the weight loss value depends on strength, and tensile splitting strength is influenced by density, with higher density producing higher tensile splitting strength. It was also found that the compressive strength test method is more realistic when using cube-shaped samples, while beam-shaped samples are more suitable for identifying bending characteristics. Finally, it was shown that the flexural strength value is influenced by density.
