Infrastructure development is one of the important aspects of the progress of a country where most of the constituents of infrastructure are concrete. The most important constituent of concrete is cement because its function is to bind other concrete materials so that it can form a hard mass. The large number of developments using cement as a building material will leave quite a lot of cement bags.In this study, the authors conducted research on the effect of adding cement waste to the compressive strength of concrete. This study used an experimental method with a total of 24 test objects. The test object is in the form of a concrete cylinder with a diameter of 15 cm and a height of 30 cm and uses variations in the composition of the addition of cement waste cement as a substitute for fine aggregate, namely 0%, 2%, 4% and 6%. K200). The compressive strength test was carried out at the age of 7 days and 28 days.The test results show that the use of waste as a partial substitute for fine aggregate results in a decrease in the compressive strength of each mixture. at the age of 7 days the variation of 2% is 16.84 MPa, 4% is 11.32 MPa and for a mixture of 6% is 6.68 MPa. Meanwhile, the compressive strength test value of 28 days old concrete in each mixture decreased by ± 6 MPa. So the conclusion is cement cement waste cannot be used as a substitute for fine aggregate in fc 16.6 (K200) quality concrete because the value is lower than the specified minimum of 16.6 MPa.

Main Material

Concrete is one of the most vital building blocks, from columns, bricks, paving to roads made of concrete, so the use of concrete tends to be high. Concrete is often used as the main buffer in a building, so good quality is needed, but this is not accompanied by a declining quality of the material, so it requires innovation in the addition of new materials that can at least reduce the needs of the main material for making concrete, one of which is the utilization of Gypsum Board waste and red brick waste. The results of testing the concrete compressive strength test with the addition of Gypsum Board waste and red brick waste to cement obtained pretty good results. Concrete, which has the highest average compressive strength than normal concrete, has concrete with a mixture of red brick and gypsum waste of 10% each with a compressive strength of 250.56 kg / cm², and which has the lowest compressive strength have concrete with a mixture of red bricks and gypsum waste 15% each with a compressive strength of 195.56 kg / cm².Beton merupakan salah satu unsur penyusun bangunan paling vital mulai dari kolom,bata, paving hingga jalan terbuat dari beton sehingga penggunaan beton cenderung tinggi. Beton sering digunakan sebagai bahan penyangga utama pada suatu bangunan maka diperlukan kualitas yang baik, namun hal tersebut tidak di sertai dengan kualitas bahan yang kian menurun,makadiperlukan inovasi penambahan bahan baru yang setidaknya dapat mengurangi kebutuhan bahan utama pembuat beton, salah satunya pemanfaatan limbah Gypsum Board dan limbah batu bata merah Hasil dari pengetesan uji kuat tekan beton dengan penambahan limbah Gypsum Board dan limbah batu bata merah terhadap semen didapatkanhasil yang cukup bagus Beton yang memiliki nilai kuat tekan rata-rata paling tinggi selain beton normal di miliki beton dengan campuran batu bata merah dan limbah gypsum masing-masing 10% dengan nilai kuat tekan sebesar 250,56 Kg/cm²,dan yang memiliki nilai kuat tekan paling rendah di miliki beton dengan campuran batu bata merah dan limbah gypsum masing-masing 15% dengan nilai kuat tekan 195,56 Kg/cm².

One of the infrastructure developments by the Indonesian government is in Merauke Regency. However, the availability of high-quality materials must be imported from outside, which results in high prices and long delivery times. Alternative construction materials continue to be sought and developed, such as the use of local materials. The aim of this research is to determine which sand is the best as mortar mixture. This mortar study used 3 (three) sands from quarries in Merauke, namely Onggari-1, Bupul-5, and Senayu. The ratio of mortar constituent between cement and sand is 1:2 with FAS 0.4, with 5x5x5 cm test object. The properties of each sand tested in original condition while the mortar compressive strength test was carried out at the age of 8 days, 14 days and 28 days. The mortar also will be tested for volume weight, specific gravity, and water absorption. The analysis results showed Onggari-1 met most of all the properties specifications for concrete with clay particles less than 5%, low organic impurities, and well-graded. The compressive strength achieved by Onggari-1 was the highest at 38,45 MPa, followed by Senayu at 26,01 MPa and Bupul-5 at 19,44 MPa at the age of 28 days. The highest increase in quality of each sand occurred at the age of 14 days. Sand from Senayu and Bupul-5 need maintenance in the form of washing the sand and repairing the gradation. Overall, all sands can be used as masonry work that bear large loads such as exterior and interior walls.
