Authors: Ridha Muhammad Hafizhir 
Published: December 2024

Soil is a material that has an important role in a construction or foundation, so that soil with good technical properties is needed. However, in reality, soil properties are often found to be unfavorable. The use of natural fibers, especially the fiber of oil palm empty fruit bunches (OPEFB) is used for soil stabilization, where there are two mechanisms to increase soil strength, namely tensile strength and soil fiber friction.This study aims to test the tensile strength of fibers that have been alkalized with NaOH compounds. Next, the OPEFB fiber is added to soft soil, compacted statically, and its compressive strength is tested. All test results were compared with the results of previous studies where the fibers used were not treated. The tensile strength of the fiber treated with curing in the soil from 1 day to 28 days old, both open and closed conditions was constant and increased up to 7.23%, this condition was better than untreated fiber where the tensile strength decreased with increasing fiber age. when soaked in the soil decreased by 60.11%. Meanwhile, the compressive strength increased with increasing age of the samples both in closed and open conditions, using a mixture of OPEFB fibers that had been treated and without treatment, the compressive strength samples aged 1 day to 7 days experienced an increase of 81.46%.

Authors: Riyandi Ridho 
Published: December 2024

The flowability of concrete is one of the problems that are often found in the construction world. Therefore, flow concrete can produce homogeneous mortar and can flow into dense repeating areas. The flow concrete in this study used fly ash derived from the acid-acid power plant. Fly ash is waste from coal that has pozzolan properties. Fly ash is more environmentally friendly than cement. To add flexibility to the concrete, a superplasticizer in the form of viscocrete 1050 HE was added. The requirement for the slump test on flow concrete is 19 cm.This study was conducted using a cylinder test object with a diameter of 11 cm and a height of 22 cm and a beam test object measuring 50x10x10 cm. The fly ash content used is 0%, 20%, 30%, 40% and 60% as a substitute for cement and also uses a viscocrete superplasticizer 1050 HE added material 1% by weight of cement. Fresh concrete testing includes slump test, slump flow test and T500. Hard concrete testing is a test of compressive strength, tensile strength, and bending strength of concrete. Compressive strength testing was carried out at the age of 14 days, 28 days, 56 days and 90 days.The results showed that the flow concrete requirements were met, except for concrete with the use of 60% fly ash which did not meet the requirements. The more the use of fly ash, the lower the values of compressive strength, tensile strength and bending strength. Optimum levels were obtained for the test requirements of fresh concrete and hard concrete at a variation of 30% fly ash and 1% viscocrete 1050 HE with a slump value of 19 cm, slump flow 530 cm, T500 5 seconds, compressive strength 20 MPa, tensile strength 2.12 MPa.

Published: December 2024

Geopolymer concrete is the concrete of the future because, in its manufacture, it does not cause environmental problems; instead, it can prevent air pollution and environmental pollution. Geopolymer concrete has several advantages: suitable mechanical properties, high early strength, stable heat, and fire resistance. In the mixture, fly ash, a silicate and aluminum source, is reacted with an alkaline solution as an activator to make a polymerization reaction. To carry out the polymerization reaction, it is necessary to use Sodium Hydroxide or NaOH, which has strong basic properties as an alkaline reactant, and sodium silicate or Na2SiO3 as a catalyst.This study aims to determine the effect of using admixture on the compressive strength of 50x50x50 mm geopolymer mortar cubes. This study's ratio of the alkaline solution was 1/1, while the balance between fly ash/solution was 60/40. Planning a mixture of mortar composition, namely fine aggregate/paste of 65/35. The admixture used is Sikament LN and Sika Viscocrete 1050 HE with a curing system that is humid temperature and at room temperature. Sikament LN content is 0,3%, 1%, 1,5%, and 2% by weight of fly ash, while the Sika Viscocrete 1050 HE content is 0,8%, 1%, 1,5% and 2% by weight of fly ash. Mortar compressive strength test was carried out at 7 days, 14 days, and 28 days.In this study, the optimum grade for each use of admixture in geopolymer mortar was Sikament LN 0,3% and Sika Viscocrete 1050 HE 0,8% at humid temperature curing, which produced the highest compressive strength of 37,65 MPa and 21,26 MPa at 28 days of age. Increasing the percentage level of the amount of admixture used decreases the results of the mortar compressive strength test. The curing system shows that the mortar with the humid temperature curing system produces a higher compressive strength compared to the room temperature curing system.
