STUDI EXPERIMEN KUAT TEKAN BETON DENGAN MEMANFAATKAN LIMBAH KERAMIK DAN BATA MERAH

Normal concrete sample (1) has a compressive strength of 222.22 kg/cm, normal concrete (2) has a compressive strength of 242.933 kg/cm, concrete using a mixture of ceramic 21% and red brick 7% sample (1) has a compressive strength of 177.911 kg/cm, concrete using a mixture of 21% Ceramics and red brick 7% sample (2) has a compressive strength of 189.777 kg/cm, concrete using a mixture of 10% Ceramics and red brick 4% sample (1) has a compressive strength of 204.667 kg/cm, concrete which uses a mixture of 10% Ceramics and red brick 4% sample (2) has a compressive strength of 137,333 kg/cm. It shows that the compressive strength of concrete decreases from increasing the volume of ceramics because the ceramic surface cannot bind perfectly. The highest K-204,667 with a mixture of 10% ceramics and 4% red brick and 28-day-old concrete, while to reach the K-250, is very far away. Of the 6 samples, the average reached K-195,807.Sampel beton normal (1) memiliki kuat tekan 222,22 kg / cm, beton normal (2) memiliki kuat tekan 242.933 kg / cm, sampel beton menggunakan campuran keramik 21% dan bata merah sampel 7% (1) memiliki kuat tekan 177.911 kg / cm, sampel beton menggunakan campuran keramik 21% dan bata merah 7% (2) memiliki kuat tekan 189.777 kg / cm, sampel beton campuran 10% Keramik dan bata merah 4% (1) kuat tekan 204.667 kg / cm, sampel beton yang menggunakan campuran Keramik 10% dan sampel bata merah 4% (2) memiliki kuat tekan 137.333 kg / cm. Ini menunjukkan bahwa Kuat tekan beton semakin berkurang dari bertambahnya volume keramik, karena permukaan keramik tidak bisa mengikat dengan sempurna. K-204.667 tertinggi dengan campuran 10% keramik dan 4% bata merah serta beton berumur 28 hari, sedangkan untuk mencapai K-250 sangat jauh jauh. Dari 6 sampel tersebut rata-rata mencapai K-195.807.

This study presents an analysis of various size metal particle waste (MP) influences on Portland cement (PC) paste hydration course, concrete sample structure densification during hardening and physical-mechanical properties. Investigations have shown that MP filler accelerates maximum heat release rate in PC pastes. MP intensifies structure development in the early phase, but slows it down in later PC hydration period. After 28-days of hardening the compressive strength of the concrete samples without MP filler is about 20% higher than of samples with MP. When in concrete composition microsilica and MP fillers are used together, compressive strength of concrete sample composition is up to 50% higher than of samples with MP filler only.

Abstract. The use of coal waste (Fly Ash) is currently being developed in building materials technology, as a high-strength concrete mix material. This study aims to determine the strength of concrete by adding fly ash as a substitute for cement in high-strength concrete mixtures. This research was conducted with an experimental method to obtain results and data that would confirm the variables studied. The total number of specimens used in this study were 36 pieces with different sizes of cube tests which were 15 cm x 15 cm x 15 cm. A total of 36 concrete samples were used to test the compressive strength of concrete with a percentage of Fly Ash in 0% (normal concrete), 20%, 25% and 30% with a concrete treatment age of 7 days, 21 days and 28 days. A total of 12 more samples were used to test water absorption in concrete at 28 days of maintenance. Each percentage percentage of Fly Ash uses 3 concrete test samples. The increase in compressive strength occurs at 7, 21 and 28 days in concrete. However, the compressive strength of concrete produced by concrete using the percentage of Fly Ash is always lower than the value of normal concrete compressive strength. From testing the compressive strength of concrete at 28 days of treatment with content of 0%, 20%, 25% and 30% Fly Ash obtained results of 45.87 MPa, 42.67 MPa, 40.89 MPa, and 35.27 MPa respectively

The research aims to determine ( 1) the increase of compressive strength of concrete with addition of fly ash to be compared to normal concrete ( 2) the resistant of normal concrete and also concrete with fly ash mineral additive in 2%, 5% and 7% sulphuric acid solutions, and ( 3) the resitant of concrete with fly ash mineral additive with the increase of concentration of sulphuric acid solution in comparing normal concrete.The method employed in this research was experimental method, by preparing the test object constituting the concrete cylinder with Æ 150 mm and 300 mm height for the compressive strength test. With the percentage of fly ash addition are 0%, 20%, 30% and 40% from requirement cement and qualities of designed concrete is 22,5 MPa. Amount of object test to the each condition is 4. To know concrete resistant in sulphate aggression environment, hence conducted by immersied of concrete in sulphuric acid solutions with concentration 2%, 5% and 7% during 30 days.From the research, it can be found that: ( 1) the addition of fly ash into fresh concrete will improve compressive strength of concrete. At addition fly ash 20% from requirement cement, compressive strength of concrete increase 23,39%. For the addition of fly ash 30% and 40%, the increase of compressive strength concrete were 21,54 % and 0,31%. While in optimum percentage of fly ash addition is 23,46% (2) the immersied concrete in sulphuric acid solution result degradation compressive strength of concrete. At the same concentration of sulphuric acid solution, concrete with fly ash additive mineral have resistant which is better to be compared to normal concrete. This seen [at] percentage of compressive strength degradation of fly ash concrete which is smaller to be compared to normal concrete. Equally the percentage of compressive strength degradation inversely proportional with the percentage of fly ash addition ( 3) the increase of concentration of sulphuric acid solution will be result of aggression that happened at ever greater. If compared to normal concrete, concrete with fly ash in the reality more effective if used at high concentration of sulphuric acid solution. This matter can be seen from difference of percentage of compressive strength degradation ever greater at the height of concentration of sulphuric acid solution.
