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.

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.

Concrete construction technology is directed to be sustainable and ecofriendly. The waste of the candlenut shell as a substitute for the coarse aggregate of concrete mixture is known that the candlenut shell has a hard texture so it may be used as a substitute for coarse aggregates in concrete. The purpose of the research was to determine the effect of Candlenut shell as a substitute of coarse aggregate on physical properties (slump test, bleeding, segregation, volume weight) and mechanical properties (compressive strength and tensile strength) of concrete using Candlenut shell as replacement material of the coarse aggregate. The variation of the research was percentage of the Candlenut shell in the concrete mixture, that was 0%, 25%, 50%, 75% and 100% to the coarse aggregate volume in the concrete mixture. Number of specimens in reseach was each 5 pieces each variation. Testing of mechanical properties of concrete (compressive strength and tensile strength) was performed at 28 days. Testing of the concrete for compressive strength test and tensile strength on age 28 days. Concrete using candlenut shell as a substitute of coarse aggregates has decreased compressive strength respectively 11.72 MPa (37.71%) for 25% candlenut shell; 15.54 MPa (50.00%) for 50% candlenut shell; 18.35 MPa (59.02%) for 75% candlenut shell; And 18,85 MPa (60,66%) for 100% candlenut shell from of the 0% candlenut shell with compressive strength of 31.08 Mpa. Concrete using for 25% candlenut shell as a substitute for coarse aggregates decreased tensile strength respectively of 0.95 MPa (28.70%) for 25% candlenut shell; 1.21 MPa (36.56%) for 50% candlenut shell; 1.27 MPa (38.37%) for 75% candlenut shell; And 1.40 MPa (42.30%) for 100% candlenut shell from of the 0% candlenut shell with the tensile strength of BN of 3.31 MPa. The decrease in the value of compressive strength and tensile strength is strongly influenced by the increasing percentage of Candlenut shells on concrete

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.

On-site fabricated CHB with several percent of carbonized biomass (CB) as substitutes for sand (0%, 20%, and 50% CB), including commercial CHB, are subjected to volume, weight, density determination, and ultimate compressive strength test. The gathered data undergo analysis through one-way ANOVA to determine the difference among the gathered compressive strength of CHB produced with different percentages of carbonized biomass. Cost analysis was also done to determine the costs and profitability of the CHB. As a result, the CHB with carbonized biomass as bonding agent produced CHB with low density, ultimate compressive strength better than commercially available CHB (with proper curing applied), and can be more profitable with increasing the carbonized biomass content.

The investigation of sawdust ash (SDA) as a partial replacement for cement in concrete was studied owing to the high cost and increasing demand for cement in a harsh economy and considering the presence of limited construction materials and waste to wealth policy. Ordinary Portland Cement (OPC) was replaced by 0%, 5%, 10%, 15%, 20%, 25% and 30% of SDA. Slump test and consistency test (flow table apparatus test) were conducted on the freshly mixed concrete sample, and compressive strength test was conducted on the hardened concrete cubes of 150mm2, which was cured between 7, 14, 21 and 28 days. The results revealed that the slump decreases as the SDA content increases in percentage, while the consistency of the freshly mixed concrete remarkably moves from high, medium to low as the SDA content increases. The compressive strength of the hardened concrete undergone a decrease in strength, as the partial replacement of OPC with SDA increases. By the results interpretation, it is observed that 5% to 10% SDA when replaced with OPC can still result in the desired strength of concrete.

<p class="abstract">At this time the manufacture of products using waste has been developed. One of them is a cone block. In this study, the addition of green glass powder material will be carried out in order to determine the effect on the quality of the cone block. The addition of green glass powder aims to determine the difference in compressive strength against the conventional model cone block. The silica content contained in green glass powder is in the form of pozzolanic substances, a substance in the form of a cement-like content and can replace cement. This study modified the cone block with a mixture of green glass powder from a percentage of 8%, 10% and 15%.</p>Penbased on previous research which states that the addition of more than 10% silica will affect the cone block structure. Tests carried out on cone blocks, namely the compressive strength test. The results of the cone block research on the compressive strength test, in general, the mixed cone block of 8%, 10% and 15% compressive strength decreased due to the slowing of the binding process due to the reduction of the cement element except for the cone block aged 14 days with a mixture percentage of 8% which had an increase.
