Abstract

In the current technological era, concrete is one of the most widely used building materials in the world, including in Indonesia, therefore good quality concrete will greatly support structural safety. Indonesia is also a developing country that has quite advanced industrial prospects. Glass waste and ceramic waste are increasing in volume every day because many human activities produce glass and ceramics. Most of the glass and ceramic waste is directly disposed of in open areas. This of course will pollute the environment, considering that glass and ceramics are non-recyclable materials. naturally repeated by nature. This study aims to reduce the impact caused by waste glass and ceramic shards that are disposed of directly into nature. By using word powder as a partial replacement for fine aggregate (sand) at a constant 10%, and using ceramic shards as a partial replacement for coarse aggregate at 30%, 40%, and 50%, the compressive strength results are 21.02 MPa, 21.31 MPa, and 26.21 MPa. And the resulting flexural strength is 3.87 MPa, 3.87 MPa, and 3.60 MPa.

Abstract

Produksi semen semakin meningkat seiring dengan peningkatan pemakaian beton. Hal ini menimbulkan masalah karena untuk setiap ton semen yang diproduksi, akan menimbulkan lebih dari tigaperempat ton CO2 yang dapat meningkatkan pemanasan global. Oleh sebab itu reduksi penggunaan semen harus dilakukan, salah satunya dengan membuat beton tanpa semen. Tahun 1978, Joseph Davidovits menemukan bahwa cairan alkalin bisa mereaksikan silikon (Si) dan alumunium (Al) dalam abu terbang menghasilkan binder untuk merekatkan agregat membentuk beton Geopolymer. Penelitian ini menggunakan beton konvensional dengan menggunakan semen sebagai beton control. Kemudian dibuat beton geopolymer dengan penggunaan  agregat yang sama, dengan  activator (NaOH: Na2SiO3 dengan perbandingan 2:5), membuat campuran dengan menggunakan prekursor -Abu terbang dan Abu sekam padi dengan perbandingan 100%:0%(BG0), 90%:10%(BG1), 80%:20%(BG2) dan 70%:30%(BG3). Selanjutnya dibuat perbandingan Aktivator dan Prekursor 4 : 3. Hasil pengujian kuat tekan pada umur 7 dan 28 hari  menunjukkan bahwa kuat tekan beton normal lebih rendah dibanding BG0 dan tidak berbeda signifikan dengan BG1. Sedangkan ratio hasil tekan 7 dan 28 hari bersesuaian dengan ratio kuat tekan 7 dan 28 hari PBI”71 yakni 0.6. Selanjutnya setiap  penambahan Abu Sekam Padi 10 % untuk menggantikan abu terbang akan menurunkan kuat tekan sebesar 2 - 3 MPa. Cement production is increasing along with the increase in concrete use. This creates a problem because every ton of cement produced will emit more than three-quarters of a ton of CO2 which can increase global warming. Therefore, cement use must be reduced, one of which is by making cement-free concrete. In 1978, Joseph Davidovits discovered that alkaline liquid could react with silicon (Si) and aluminum (Al) in fly ash to produce a binder to bond aggregates to form Geopolymer concrete. This research uses conventional concrete using cement as control concrete. Then geopolymer concrete is made using the same aggregate, with an activator (NaOH: Na2SiO3 with a ratio of 2:5), making a mixture using precursors -fly ash and rice husk ash with a ratio of 100%:0%(BG0), 90%:10 %(BG1), 80%:20%(BG2) and 70%:30%(BG3). Next, a 4:3 comparison of Activator and Precursor was made. The results of compressive strength testing at 7 and 28 days showed that the compressive strength of normal concrete was lower than BG0 and not significantly different from BG1. Meanwhile, the compressive yield ratio of 7 and 28 days corresponds to the compressive strength ratio of 7 and 28 days PBI"71, namely 0.6. Furthermore, each addition of 10% Rice Husk Ash to replace fly ash will reduce the pressure by 2 – 3  MPa..

Abstract

When constructing buildings in coastal areas, contact between the materials used and sea air is sometimes unavoidable. Before the concrete reaches its maximum strength at the age of 28 days, it can be exposed to contamination from sea air. Consequently, chemical reactions involving cement, air, and sea air become inevitable. The research aims to ascertain the microstructure, porosity, and mechanical properties (compressive strength and tensile strength) of high-performance concrete utilizing the Self Compacting Concrete method. Two variations of concrete samples are considered, involving differences in the curing water used and the age of the concrete. There are two curing variations: concrete cured with fresh water and concrete cured with seawater. The concrete's age is monitored at 1, 3, 7, 28, and 90 days. In the microstructure analysis of seawater-cured concrete, chloride compounds, ettringite, and Friedel's salt were identified. Both compressive strength and splitting tensile strength show an increase with the concrete curing age, and they are inversely proportional to the concrete's porosity. The mechanical properties of freshwater-cured concrete are slightly lower than those of seawater-cured concrete. However, the difference is negligible, meaning they are nearly identical at both 28 days and 90 days.

Abstract

Research on increasing the compressive strength of concrete by using various types of additives has been widely carried out, so this research also uses additives, namely the use of banana stem ash and palm shell ash, which aims to determine the comparison of the two additives, as well as the effect of adding concrete. Contains Sikacim Concrete Additive. Variations in banana stem ash and palm shell ash (4%, 5% and 6%) of the cement weight as well as the addition of Sikacim Concrete Additive as much as 0.6% of the cement weight. The average compressive strength of the concrete samples was measured and compared. The research results showed that the higher the percentage of banana stem ash and palm shell ash used, the higher the compressive strength of the concrete produced. The compressive strength of variations in banana stem ash is greater than variations in palm shell ash with percentages of 14.13%, 11.17% and 7.08. The effect of adding sikacim concrete on banana stem ash was 3.17%, 1.39%, 6.73 and on palm shell ash was 2.88%, 4.32%, 3.99% compared to before adding sikacim. Banana stem ash at a percentage of 6% with the addition of sikacim had the highest increase with a compressive strength of 29.91 Mpa.

Abstract

Clay soils in general can be said to have a low carrying capacity. Therefore, it needs to be treated if it will be used as a construction base. This study aims to determine the effect of adding Na2CO3 (sodium carbonate) on the consistency and shear strength in clay soils. This study was conducted by preparing a mixture of various concentrations of Na2CO3, namely 0.4%, 0.6%, 0.8% and 1.0%, which were added to clay soil samples, which is added to clay soil samples. Consistency testing using the Atterberg limit test (Casagrande Stone). The results showed that the addition of Na2CO3 had an influence on the consistency of clay soil. In the shear strength test, there are values of cohesion, shear angle and shear strength, where the percentage of mixture increases. So that in this test the optimum shear strength value can be obtained on a mixture of 1% Na2CO3 soil.
