“…Though an equal volume of M-sand is replaced for R-sand as a fine aggregate, because of the higher density of M-sand compared to R-sand, the density of the concrete mixes produced with M-sand is higher. Similar trends are found in the literature [58][59][60][61][62][63][64]. If CCM fresh concrete mix density is compared with CC fresh mix concrete density, then the CCM mix density is 4.23% higher than the CC mix density.…”

“…Therefore, there is no need to hesitate to use M-sand as a 100% replacement alternative for R-sand in the production of concrete on an equal volume basis for the selected mix proportion from a strength point of view. The same trends of enhancement of strength of concrete mixes when using M-sand in place of R-sand were found in the reports published on the use of this kind of M-sand and quarry dust by other researchers [58][59][60][61][62][63][64].…”

Natural resources are being continuously extracted for the production of concrete which leads to degradation of the ecosystem. This is also a challenge for sustainability to save Nature. This study seeks to identify a suitable replacement material for river sand and stone aggregate for the sustainable utilization of renewable sources. Manufactured sand (M-sand) from industrial by-products and coconut shell (CS), an agricultural waste, are the resources selected as replacement materials for sustainability. This study uses M-sand as fine aggregate and CS coarse aggregate in place of river sand (R-sand) and crushed stone aggregate (CSA) for concrete production, respectively. To prove that M-sand and CS are sustainable alternate materials, this study focused on the microstructural characteristics on concrete constituents and CS aggregate and also conducted on concrete produced using R-sand, M-sand and CS. Also, this study focused on the microstructural characteristics and properties of conventional concrete (CC) and coconut shell concrete (CSC) produced using both R-sand and M-sand. Since this study aims to find sustainable alternative materials for R-sand and CSA by M-sand and CS, its properties are studied and compared since microstructural characterization is very significant for concrete compatibility. Microstructural studies revealed that the use of M-sand does not affect the microstructural properties of concrete compared to R-sand concrete and rather it improves the strength of concrete. A similar same trend was observed when CS was used with M-sand compared to CS used with R-sand. Hence, this study strongly suggests that the use of M-sand in its place of R-sand and CS in its place of CSA are sustainable alternatives for the production of concrete so that natural resources can be saved and hence sustainability could be sustained.

Concrete in technological development has progressed very rapidly, so that it is able to open ideas in the use of organic materials as an alternative material for concrete. Genitri seeds are an organic material that can be used as an alternative to the building blocks of concrete. Genitri seeds have very good hardness and have a light volume weight so that they can reduce the large structure weight due to the weight of the concrete itself. The research method used in this study is an experimental method with genitri seeds as a mixture of coarse aggregate in concrete. This study aims to determine how much influence the compressive strength, slump value, volume weight, absorption, using a mixture of genitri seeds with a percentage of 5%, 10%, 15% of the weight of coarse aggregate. The results showed that the highest compressive strength was obtained by the addition of 5% genitri seeds, namely 20.75Mpa with an average slump value of 5.2. In the absorption test, the value of ¼ hour 0.040 1 hour 0.022 4 hours 0.006 24 hours 0.002 was obtained.Beton dalam perkembangan teknologi mengalami kemajuan yang sagat pesat, sehingga mampu membuka pemikiran dalam pemanfaatan material organik sebagai bahan alternatif penyusun beton. Biji genitri merupakan salah satu bahan organik yang dapat digunakan sebagai alternatif material penyusun beton. Biji genitri memiliki kekerasan yang sangat baik dan memiliki berat volume yang ringan sehingga dapat mengurangi berat struktur yang besar akibat beban dari berat beton itu sendiri. Metode penelitian yang digunakan pada penelitian ini adalah metode eksperimental dengan biji genitri sebagai bahan campuran agregat kasar pada beton. Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh terhadap kuat tekan, nilai slump, berat volume, absorpsi, dengan menggunakan bahan campuran biji genitri dengan persentase 5%,10%,15% dari berat agregat kasar. Dari hasil penelitian menunjukkan bahwa kuat tekan tertinggi diperoleh dengan penambahan biji genitri sebesar 5% yaitu 20,75Mpa dengan nilai slump rata-rata 5,2. Pada pengujian absorpsi diperoleh nilai ¼ jam 0,040 1 jam 0,022 4 jam 0,006 24 jam 0,002.
