Abstract

The utilization of nanosilica and cellulose nanocrystals (CNCs) in cement geopolymers remains challenged by intricacies and uncertainties regarding their concentration, posing difficulties in the formulation of systematic geopolymer mix designs. This study aims to formulate models based on Artificial Neural Networks (ANN) capable of forecasting the compressive strength of geopolymers through the utilization of experimentally acquired data. Nanosilica was applied at concentrations of 2%–4% and CNCs at 1%–3%. ANN was modeled using MATLAB to predict the compressive strength of the geopolymer. The results indicated an effect of nanosilica and CNCs on the compressive strength of geopolymer at 2%–4% concentration and 1%–3% CNCs. The best ANN was the GDX training function, purelin activation function, LGD and LGDM learning functions, Lr 0.1 and 0.01 at the number of epochs 3812 out of 25000 and 1774 out of 25000, resulting in the best correlation values of 0.994 and 0.959; the lowest RMSE values are 0.022 and 0.110. The results of the ANN model built based on actual data prove that the model is helpful for accurate simulation to predict the compressive strength of geopolymer cement. This study contributes novelty by optimizing the design model for Geopolymer Cements incorporating nanosilica and CNCs. Doi: 10.28991/CEJ-SP2024-010-03 Full Text: PDF

Abstract

This study investigates using Coconut Shell Charcoal (ABK) as a stabilizing agent for clayey soils, aiming to enhance their suitability for road subgrade applications. The primary objective is to evaluate the effect of varying ABK concentrations (0%, 5%, 10%, and 15%) on the geotechnical properties of clay soil, particularly its compaction and load-bearing capacity. Laboratory tests, including compaction and California Bearing Ratio (CBR), were conducted to assess the influence of ABK on soil strength and stability. The results reveal that adding ABK significantly improves the soil's compaction characteristics and CBR values. The highest improvement was observed at 15% ABK, where the CBR value reached 22.22%, well above the minimum threshold required for road subgrade materials. There is a good influence of coconut shell charcoal on increasing the CBR value of clay soil subgrade at each additional material. The R value of 0.963 obtained shows a very high correlation. The addition of coconut shell charcoal to the subgrade soil has a positive effect on the California Bearing Ratio value which increases in each variation. The study demonstrates that ABK, a sustainable agricultural waste product, provides an affordable and effective solution for enhancing the strength and stability of clay soils, making it a promising alternative to traditional stabilizers such as lime and cement. The findings have significant implications for road construction in regions with expansive and weak soils, offering a cost-effective and environmentally friendly method for soil stabilization. This research contributes to the growing body of knowledge on the use of agricultural waste in infrastructure development, emphasizing the potential of ABK in providing sustainable solutions for soil improvement in civil engineering applications.

Abstract

Steel fibers that function as small-sized reinforcements. The purpose of this study was to analyze the physical properties of sand in the form of specific gravity, bulk density, sieve analysis, fineness modulus. And analyze the mechanical properties in the form of compressive strength. Steel fibers used with variations of 0%, 1%, 2%, and 3% of the total weight of cement with a fiber length of ± 1cm. The test objects in this study were in the form of cubes with a diameter of 5cm x 5cm x 5cm and a volume of 125cm3 with a total of 36 test objects. The results of the specific gravity examination of fine aggregates using 3 samples, namely A, B, and C, obtained an average saturated surface dry density (SSD) of 2.67, an average oven dry density of 2.56 and an average water absorption of 3.96%. The results of the bulk density examination were 1.826 kg / l. The results of sieve analysis show that the aggregate used is included in the aggregate category as sand (zone II) with a fineness modulus value of 2.86, with a fineness requirement of 1.5 - 3.8. The results of mechanical properties in the form of a pressure test on mortar at the age of 7 days experienced a decrease in succession from M0 18.24 MPa by 17.5%, 11.3%, and 7.7%, with a value of M1 15.05MPa, M2 16.19 MPa, and M3 16.84 MPa. For mortar aged 14 days also experienced a decrease in succession from M0 18.25 MPa by 9.7%, 5.6%, and 1% with a value of M1 16.48 MPa, M2 17.24 MPa, and M3 18.08 MPa, due to the Bonding Stringht mechanism. Meanwhile, for 28 day old mortar, the M0 18.48 MPa increased successively by 1.1%, 3.4% and 11.5% with values of M1 18.48 MPa, M2 19.11 MPa and M3 20.61 MPa.

Abstract

Concrete is a construction material that is often used in various applications such as buildings, bridges and other infrastructure. Concrete compressive strength is one of the most important parameters for determining the structural strength of a building. And concrete compressive strength is a major concern in the construction industry. One of the common problems with concrete is the risk of cracking. Especially under dynamic loads or extreme temperature changes. Therefore, as time goes by, many innovations have been made in the development of concrete, one of which is by adding fiber to the concrete mixture. This research aims to find out what is the optimal percentage for adding hooked steel fibers to the concrete mixture.  The research method includes making and testing concrete samples with different steel fiber content variations, namely 0.5%, 1%, 1.5% and 1.8% using FAS 0.4. Compressive strength testing is carried out after the concrete reaches the age of 28 days. The research results show that the most optimal addition of steel fiber in concrete is a percentage of 0.5% with an average compressive strength of 348.20 Kg/cm². This increase is caused by the ability of steel fibers to resist crack propagation and micro tensile stress. However, if the fiber content is too high, there is a decrease in workability which causes the compressive strength of the concrete to decrease.
