Abstract

In general, clayey soil has low bearing capacity; therefore, clayey soil needs to be improved in terms of its bearing capacity before constructing anything on it. This research aims to utilize fertilizer to enhance the CBR (California Bearing Ratio) and reduce the permeability of clayey soil. One way to improve clayey soil is by incorporating fertilizer as a soil stabilization material, by conducting CBR and Permeability Tests. Urea fertilizer readily dissolves in water and exhibits easy water absorption properties (hygroscopic). On the other hand, NPK fertilizer is a compound fertilizer containing nitrogen (N), phosphorus (P), and potassium (K) in varying compositions, with each element represented by the initial letter of its name (N, P, and K). In this study, 10% Urea is added to the soil, and there is variation in the amount of NPK, namely 0%, 5%, 10%, and 15%. The research results indicate that with the addition of NPK fertilizer, the CBR value continues to increase compared to the original soil and soil with only urea mixture. Meanwhile, in the Permeability Test, with each addition of NPK fertilizer, the coefficient of permeability value experiences a decrease.

Abstract

The high demand for concrete in construction has increased the need for concrete materials, driving the mining of rocks as a primary component of concrete. Using simple technology that utilizes local resources, including waste as building materials, is essential for concrete technology development. Candlenut shells are a new potential material due to their hard texture. This study uses a design strength of 25 MPa for normal concrete, aiming to observe the effect of using candlenut shells as a partial coarse aggregate replacement with added Silica Fume on concrete's compressive and flexural strength. The mixing method involves replacing coarse aggregate with candlenut shells in 5%, 10%, and 15% proportions. Silica Fume is added at 20% of the cement weight for concrete without candlenut shells and with shell variations at 5%, 10%, and 15%. Results show that adding candlenut shells reduces compressive and flexural strength, but adding Silica Fume enhances both strengths. Notably, the 5% candlenut shell variation with 20% Silica Fume shows higher strength than normal concrete.

Abstract

Indonesia is a developing country with rapid progress in infrastructure and technology. Cement production requires a significant amount of energy and generates considerable waste. Innovation is essential to create construction materials that are cost-effective, energy-efficient in production, and produce minimal carbon dioxide and other hazardous waste. The use of silica fume as a partial replacement for cement, combined with paper pulp and superplasticizer in concrete mixtures, is expected to enhance concrete strength. This approach may also help reduce environmental pollution from cement production. In this study, 10% of the cement in each sample was substituted with silica fume, with paper pulp added at 0%, 3%, and 6%, and superplasticizer at 2%. The target strength for normal concrete is 25 MPa. The results show that using silica fume as a partial cement replacement can increase compressive strength by 3.36% and flexural strength by 7.24%. However, when silica fume is used with paper pulp, compressive and flexural strengths decrease. Adding both paper pulp and superplasticizer alongside silica fume results in an increase in strength, though the improvement is not significant.

Abstract

With the advancement of technology and increasingly complex construction needs, the use of concrete has become essential in infrastructure development. One innovation to improve concrete quality is by adding supplementary or replacement materials. In Indonesia, iron powder is rarely utilized, leading to environmental pollution. This study uses iron powder to partially replace sand, aiming to address waste issues, and incorporates silica fume to partially replace cement. The mixing method replaces sand with 5%, 10%, 15%, 20%, and 25% iron powder and adds 10% silica fume relative to the cement amount in each iron powder variation. Results show that using iron powder and silica fume increases compressive and flexural strength at 5% and 10% iron powder with 10% silica fume. However, iron powder at 15%, 20%, and 25% with 10% silica fume led to reduced strength. Maximum compressive and flexural strength occurred at 10% iron powder with values of 27.55 MPa and 5.07 MPa, indicating that higher iron powder levels reduce compressive and flexural strength.
