“…Hal ini dikarenakan material cangkang memiliki properti mekanik yang cukup unik. Material ini dapat digunakan untuk meningkatkan kuat tekan beton [1]. Secara umum, bahan cangkang memiliki kekerasan yang cukup tinggi, baik dari segi kekuatan terhadap tekan, tarik, dan gesernya, dibandingkan dengan material kayu sebagai material bangunan.…”

The background of this research is that there is still a lot of oyster shell material that has not been utilized, meanwhile the shell has good mechanical properties as well as concrete. Up to this moment, the shell is not used properly so it needs to studied the use as concrete mixture. By the utilization of this waste is expected to reduce the environmental impact. This study was aims to obtain a regression equation of the compressive strength of concrete using shells, the shells used in this study were oyster shells (ostreidae), tested at 28 days of age with 3 variations in the percentage of the use of shell ash material and with 1 variation of normal concrete. The percentage variations used are 0% variation, 5% variation, 10% variation, and 15% variation. In addition, based on the regression equation, the strong relationship between variables will be obtained which is indicated by the value of r square. The implementation of this research was carried out by carrying out a compressive test of concrete cylinder samples with 3 variations of the water cement rasio (W/C), is W/C 0.4, W/C 0.5, and W/C 0.6. The activity was continued by recording and analyzing data by conducting a regression analysis between the relationship between the percentage of shell use and the compressive strength of concrete. The regression equation used is the exponential regression equation, linear regression, polynomial regression order 2. From the test data, it is found that the regression equation is the best for W/C variation 0.4, obtained polynomial regression equation order 2, y = -0.0351x2 + 0, 3279x + 25.075 with r² = 0.9999, for the W/C variation of 0.5, the second order polynomial regression equation is obtained, y = -0.0702x2 + 0.8062x + 23.406 with r² = 0.8983, and for the W/C variation of 0.6 , the second order polynomial regression equation is obtained, y = -0.0404x2 + 0.4008x + 19.074 with a value of r² = 0.9167..

“…The percentage of ceramic waste mixture that has the highest compressive strength is 9%, and if it the >9% then the compressive strength of concrete will decrease. Ceramic waste can be used as an alternative to fine aggregates of a maximum of 9% (Karimah, Rusdianto, & Susanti, 2020).…”

<p>Every building renovation or building reconstruction often occurs demolition of the wall. The demolition of this wall becomes construction waste therefore it is necessary to experiment with using wall waste to become a productive material. This research is an experiment in making concrete using wall waste. The wall waste used is in the form of rubble from the ruins of a red brick wall. The compression test method refers to the 1974:2011 SNI regulations on concrete. In this test, the focus is on the maximum compressive strength of concrete that can be produced in the sample. Each sample of the test object is divided into three groups, each group has three test objects. The first group is a sample of pure concrete, fine aggregate 100% concrete sand. The second group is a fine aggregate experimental concrete sample containing 25% wall waste, and the third group contains 50% wall waste. The test object is in the form of a concrete cylinder with a diameter of 150 mm and a height of 300 mm. Concrete testing is carried out at the age of 7 days, 14 days, and 28 days. The results of this study provide information that red brick wall waste can be recycled into concrete material so that it does not become construction waste. It is known that the compressive strength of concrete using additional wall waste as fine aggregate meets the requirements of structural concrete quality and can improve the quality of concrete. Furthermore, it is hoped that the wall waste can be reused as an added material to the concrete mixture in building construction activities or other construction using concrete.</p>

“…Besarnya peningkatan kebutuhan material pembuatan beton menyebabkan banyak penambangan agregat baik kasar dan halus sebagai salah satu material campuran beton secara besar yang menyebabkan berkurangnya jumlah sumber alami yang tersedia untuk pembuatan beton Sekarang sumber pengahasil pasir alami kini persedianya semakin menipis [1], [2]. Perkembangan ilmu teknik sipil di bidang kontruksi gencar di lakukan dalam beberapa dekade terakhir dengan tujuan untuk menginovasikan bahanbahan pencampuran beton yang ramah lingkungan dan juga memilki kuat tekan [1]- [3]. Nilai kekuatan beton dipengaruhi oleh material pencampurannya, muncul gagasan untuk memanfaatkan limbah sebagai bahan sustitusi maupun bahan tambah.…”

The development of concrete technology in trials of adding mixed ingredients continues to be carried out to obtain the desired strength and quality of concrete. The clam shells contain pozzolanic chemical compounds, namely lime which is expected to be used as a substitute for fine aggregate in a mixture of concrete constituents. This research was conducted to determine the compressive strength of concrete by utilizing shell waste as a substitute for fine aggregate of 0%, 15% and 25% with aging observed at 7, 14 and 28 days. This research carried out several material tests such as sieving, aggregate specific gravity, moisture content, silt content, wear and tear, organic matter, slump test and concrete compressive strength test. Based on the results of the study, it was found that the optimum strength in mixed variations with shell waste as a substitute for 15% fine aggregate obtained a compressive strength value of 14.09 MPa at 14 days. From the results of the research conducted, it can be concluded that the use of shell waste as a substitute for fine aggregate is not recommended for the manufacture of concrete in the world of construction, because the strength value of the concrete obtained does not meet the requirements of Standard SNI 7656: 2012
