Abstract

Soil is an important component in building construction because it supports the structure. Clay soils often pose problems due to their high potential for swelling and shrinkage, which can result in cracking and building settlement. Stabilization of clay soil is an important solution. This research aims to evaluate the effect of recycled aggregate concrete (RCA) from laboratory construction waste on the characteristics of clay soil. The research method involved laboratory experiments, with a mixture of clay and RCA at 5%, 10%, and 15% variations. Testing includes Atterberg Limit, Standard Proctor Test, and Unconfined Compressive Strength (UCS). The results showed that adding RCA increased clay soil's bearing capacity and shear modulus. The peak bearing capacity was achieved by adding 5% RCA, with a Qu value reaching 265.24 kN/m². The shear modulus also increased from 41.63 MPa to 62.442 MPa with the addition of 5% RCA. Thus, the addition of RCA from laboratory construction waste can increase the bearing capacity and shear modulus of clay soil to support construction safety and the principles of sustainable development.

Abstract

Concrete is the primary material in construction, so it needs further research to get good quality concrete. The quality and durability of concrete are influenced by the amount and shape of the air cavity inside the concrete. With vibrating, the air that is inside the concrete will be lost. The benefits of vibration will only be achieved if planned and implemented with a suitable method. With proper vibration, the air in the concrete will come out and make porous concrete. Reduction or removal of air cavities will make concrete mixes strong with low permeability, increasing the durability of concrete. This study aims to determine the optimum strong vibrating on the compressive strength of Fc' 21,7 Mpa concrete. Vibrating will be performed on cylinder concrete samples with a duration time of 3 minutes and with different variations in acceleration 160 m/s2, 170 m/s2, 180 m/s2, 190 m/s2, 200 m/s2, variation velocity 140 mm/s, 150 mm/s, 160 mm/s, 170 mm/s, 180 mm/s, displacement variation 600 mm, 800 mm, 1000 mm, 1200 mm, 1500 mm. Each variation consists of 7 concrete samples. These tests were performed with methods of external vibrating by using MBT Vibrating table CO-410 in fresh concrete. Compressive strength testing is carried out at 28 days. This study shows that the optimum strong vibrating with acceleration 180 m/s2, velocity 160 mm/s, and displacement 1000 mm with the resulting compressive strength is Fc' 23.06 MPa. So that knowing the optimum vibration strength can be the basis for the implementation of vibration to get the planned concrete quality.

Abstract

Using rice husk ash (RHA) in concrete technology represents a significant innovation in promoting sustainability. The pozzolanic properties of RHA enhance concrete quality through microstructural refinement while mitigating environmental impacts. However, replacing 10% of cement with RHA has inconsistent effects on compressive strength. Such variability may limit the broader application of RHA in structural concrete due to uncertainties in performance prediction, quality assurance, and design safety. While some studies report strength improvements, others note reductions often attributed to limited samples size, material inconsistencies, and variations in mixing or curing processes. This study aims to statistically validate the consistency of compressive strength in concrete with 10% RHA substitution by increasing the sample size and controlling key variables. Nine specimens per test condition were evaluated using a water-cement ratio of 0.53, submersion curing and ASTM C39 testing standards. Compressive strength assessment was conducted at 7 days. The result show a 7.54% increase in compressive strength, from 22.71 MPa to 24.42 MPa, with a coefficient of variation (CV) of 2.26%, well below the 10% threshold. In contrast, earlier studies with smaller sample sizes reported CVs as high as 42.65%, indicating greater statistical variability. This improvement is attributed to the increased sample size, material quality control, and uniform mixing, which ensured homogeneous RHA distribution and optimized pozzolanic reactions. By applying a controlled-variable approach and increasing the sample size, this study addresses prior inconsistencies and reinforces the validity of RHA as a viable cement substitute in concrete.

Abstract

Expansive clay soils undergo volumetric changes due to fluctuations in moisture content, which can cause structural damage to foundations, pavements, and embankments. Traditional stabilization methods, such as cement and lime, are effective but have a significant environmental impact, highlighting the need for more environmentally friendly alternatives. Lignosulfonate (LS), an organic stabilizer derived from industrial by-products, offers a more sustainable approach to improving soil strength and stability. This study evaluates the effect of 2% lignosulfonate on the unconfined compressive strength (UCS) of expansive clays. The research method involved mixing LS at 2% of the dry weight of the soil into the expansive clay (CL-ML) and conducting UCS tests on three untreated (control) samples and six treated samples. Statistical analysis was used to assess the significance of the differences between the two groups. Results show that the UCS increased from 236.29 kPa in the control group to 291.49 kPa in the treated group, reflecting a 23.37% improvement. Poisson's ratio decreased from 0.300 to 0.200, indicating reduced lateral deformation and enhanced soil stiffness, which improves the bearing capacity and stability of structures built on it. The UCS values ​​were observed to be consistent supported by low standard deviation. The study highlights the critical role of adequate sample replication and control over operational variables such as moisture content, compaction, and LS dispersion to ensure reliable and reproducible stabilization outcomes. This study strengthens the empirical basis for the application of LS as a sustainable and environmentally friendly stabilizer for expansive clays.

Abstract

Soil is a crucial element in construction, serving as the foundation for structural support. Soil compaction is one of the primary methods to enhance soil stability, especially for clay soil, which expands and shrinks due to changes in moisture content. This study aims to analyze the effect of water content variation on the maximum dry unit weight in clay soil compaction. The experimental testing was conducted in the Civil Engineering Laboratory of Kadiri University using the TS-365 Automatic Standard Proctor machine. The water content variations used were 15%, 18%, 20%, 23%, and 26%. The results showed that the optimum moisture content for achieving the maximum dry unit weight was 23%, with a maximum dry unit weight of 1,743 g/cm³. Increasing water content up to the optimum point increases soil density, but excess water reduces the dry unit weight due to particle separation. This research contributes to optimizes clay soil compaction for more stable and sustainable construction. By determining the optimum moisture content, the compaction process can be conducted more efficiently, minimizing the risk of soil volume changes and improving soil-bearing capacity for long-term infrastructure development.

Abstract

Sandy soils are commonly employed as the foundation for shallow footings. However, their relatively low bearing capacity often leads to excessive settlement and deformation. This study examines the potential application of the Enzyme-Induced Carbonate Precipitation (EICP) technique based on soybeans. Utilizing urease derived from soybeans to catalyze the crystallization of calcium carbonate (CaCO₃). This research investigates the impact of EICP-induced carbonate precipitation on the bearing capacity of sandy soil in square footings. 4 x 4 cm footing model was tested using the AIC-Innovation Loading Test apparatus. Direct shear additional tests were performed to assess differences in increase cohesion and shear angle. The results show 174.90% increase in bearing capacity, 73.47% reduction in settlement, 300.64% increase in cohesion from the shear test, and  202.46% increase from the loading test. The shear angle increased by 56.34%, and the dry unit weight increased by 36.5%. ANOVA analysis with a p-value of 2.03 × 10⁻¹⁵ < 0.05 confirmed that the increase in bearing capacity was not due to random variation but to the EICP treatment. These findings demonstrate that EICP proves to be a viable technique to enhance sandy soil and contributes to advancing of bio-cementation based on organic materials as a sustainable solution.

Abstract

Rendahnya kualitas pemadatan tanah menjadi salah satu penyebab utama kerusakan dini infrastruktur jalan, terutama karena tidak tercapainya densitas kering lapangan sesuai spesifikasi. Penelitian ini bertujuan untuk mengevaluasi pengaruh jumlah lintasan pemadatan terhadap nilai rasio Maximum Dry Density (MDD) sebagai indikator keberhasilan pemadatan tanah. Pengujian dilakukan pada proyek Jalan Tol Probolinggo-Banyuwangi Paket 3 di STA 31+166, membandingkan kedua perlakuan tersebut yaitu lintasan 8 dan 10 lintasan dengan menggunakan alat berat Vibro Roller. Data ANOVA satu arah pada tingkat signifikansi < 0,05 menunjukkan bahwa jumlah lintasan pemadatan berpengaruh signifikan terhadap rasio MDD (p = 0,038). Peningkatan lintasan menghasilkan distribusi energi yang lebih merata dan mampu meningkatkan berat isi kering lapangan. Temuan ini dapat digunakan sebagai acuan evaluasi dalam pengendalian mutu berdasarkan jumlah lintasan pemadatan yang tersedia dalam laporan proyek harian, serta memperkuat pemahaman teknis tentang hubungan distribusi energi pemadatan dengan kepadatan lapangan yang optimal.
