Abstract

The rise of the traffic volume which causes road damage due to heavy load and humidity, there must be an improvement to the quality of the road. This research uses Mount Merapi Volcanic Ash waste as a filler in The WearLayerMixture. The aim of this research is to examine if there is a difference between asphalt concrete that uses Mount Merapi Volcanic Ash as its filler and asphalt concrete that uses cement as its filler in terms of Marshall parameter. This research uses experimental method that examines Marshall parameter on five variations of asphalt level, which are 4%, 5%, 6%, 7% and 8% with 6 (six) samples of specimen on each variation. Marshall method resulting the maximum asphalt level at 6% percentage with it’s stability value which is 964,091 kilograms, flow value 3,1milimeters,Marshall Quotient (MQ) value 312,331 km/mm, Void in Mineral Aggregates (VMA) value 17,976%, Void Filled with Bitumen (VFB) value 69,939%,and Void In the Mix (VIM) value 4,947%. Based on the result of this research, it can be concluded that the Mount Merapi Volcanic Ash can be used as a filler in The Wear Layer Mixture for heavy traffic class with 6% of asphalt level.

Abstract

The purpose of this research is to know the ratio of bearing pile capacity with some static and dynamic calculation method to Pile Driving Analyze (PDA) dynamic test result. The analysis uses static calculations using several methods namely, Meyerhoff, Vesic, α Thomlinson, and α Terzaghi, Peck and Mesri methods.Consultant calculation using Reese & Wright method. Dynamic bearing capacity uses jacking pile record from Hydrolic System Pile Driving (HSPD) and Pile Driving Analyze test results. The results showed that Reese & Wright method with SPT is the most closely approximated PDA test result with percentage 74,72%; 76.79% and 82.83% for number of pile 310, 368 and 763. While the result of comparison of jacking pile record that most approached PDA is on pile number 638 with a percentage of 82.83%. The largest settlement results are at pile number 310 and 763 with a decrease of 26.3 mm and 25.9 mm with α Vesic+Terzaghi, Peck and Mesri method

Ash duck egg shell used is burnt waste with temperatures reaching 800 ° C for ± 6 hours using ceramic burning oven. This study uses cylindrical test object with diameter 10 cm and height 20 cm with the quality of plan is fc '20 MPa. Testing of compressive strength of geopolymer concrete using Crushing Test Machine tool. In this purpose, the compressive strength of the geopolymer concrete produced by the concrete test object on variations 0%; 80%; 90%; and 100% ie 0 MPa; 6,32 MPa; 8,57 MPa; and 14,01MPa, while the concrete test object No concrete compressive strength was applied on variations of 0%; 80%; 90%; and 100% ie 7,64 MPa; 4,84MPa; 5,77MPa; and 6.19MPa. It can be seen that the maximum average compressive strength value is present in the 100% variation with the tested object being tested at 83°C first.

Abstract

Beton geopolimer adalah beton yang material utamanya mengandung bahan yang bersifat pozzolan. Pozzolan adalah bahan yang mengandung senyawa Silika dan Alumina. Dengan bentuknya yang halus, pozzolan dapat direaksikan dengan alkali aktivator. Prekursor atau material alternatif pengganti semen sebagai bahan pengikat dalam beton geopolimer biasanya menggunakan abu terbang (fly ash), abu sekam padi (RHA), ampas tebu, cangkang telur dan lain “ lain, yang banyak mengandung silikon dan aluminium. Sebagai aktivator pada umumnya digunakan natrium hidroksida (NaOH) dan sodium silikat (Na2SO3). Material alternatif pengganti semen yang digunakan dalam penelitian ini adalah abu sekam padi. Abu sekam padi dapat digunakan sebagai alternatif pengganti semen dikarenakan abu sekam padi bersifat pozzolan dan mengandung Silika sekitar 87-97%. Zat kimia tersebut adalah zat yang terdapat pada semen. Abu sekam padi pada penelitian ini akan dibakar hingga suhu ±800oC. Alkali aktivator yang digunakan adalah natrium hidroksida (NaOH) dan sodium silikat (Na2SO3) dengan perbandingan 65% : 35%; 70% : 30%; dan 75% : 25% dari berat prekursor.

Pozzolan is an ingredient that contains silica and alumina compounds. With its smooth shape, pozzolan can be reacted with an alkaline activator.Precursors or alternative materials to replace cement as a binder for geopolymer concrete typically use fly ash, rice husk ash, sugarcane bagasse, egg shells, and other materials that contains a lot of silicon and alumunium. Materials such as sodrium hydroxide (NaOH), and sodium silicate (Na2SO3) are generally used as activators. The alternative ingredient used as replacement for cement used in this study is rice husk ash. Rice husk ash can be used as an alternative replacement for cement because rice husk ash is pozzolanic and contains about 87-97% of silica. These chemical substannces are generally found in cement. In this study, the rice husk ash is burned with temperatures up to ±800oC. Alkaline activators used in this study are sodrium hydroxide (NaOH), and sodium silicate (Na2SO3) with a ratio of 65% : 35%; 70% : 30%;and 75% : 25% by the precursors weight.This study aims to calculate the mix design using SNI 03-2834-2000 about the procedures for making a normal concreat mix designKeywords: Geopolimer, Na2SiO3, NaOH, Prekursor, RHA
