Abstract

Peat water containing a low pH is not recommended as concrete mixing water. Water has a pH below 7 is acidic water. The acidity of peat water can damage the quality and service life of concrete in the long term. The addicid of the added material such as oil ash or Palm Oil Fuel Ash (POFA) may increase the formation of calcium silicate hydrate as a gel adhesive concrete. This study aims to measure the mechanical properties such as compressive strength, tensile strength and modulus elasticity of concrete with a compressive strength of 35 MPa. Concrete compressive strength OPC and OPC + 10% POFA using peat water as mixing water has decreased by 8.33% and 6.33% of the compressive strength of normal concrete. The results of tensile strength and modulus of elasticity sides show strong results in line with the press. The use of oil ash or Palm Oil Fuel Ash (POFA) showed a decrease in mechanical properties is smaller than OPC concrete with peat water as mixing water. The compressive strength of concrete using peat water as mixing water has a value of compressive strength greater than 90% of the compressive strength of normal concrete, so the peat water is still fit for use as concrete mixing water with treatment (curing) of plain water.Keywords: OPC, mechanical properties, palm oil fuel ash, peat water.

Abstract

Artificial geopolymer aggregates is one of many methods on making aggregates in case for substitution of natural aggregates. The main ingredients of thisgeopolymer is a material that contains silica and aluminium in a great numbers. In the province of Riau fly ash (FA) and palm oil fuel ash (POFA) are waste materials that until this time did not get utilized optimally whereas this materials are verypotentially for geopolymerization. NaOH and Na2SiO3 are used as alkaline activators, NaOH molarity (0, 8, 10 and 12M ) used as variation on sample composition. The highest compressive strength based on variation is using as the next sample artificial aggregates composition with 1-2cm size of diameters. Researchshowed that 12M variation results the highest compressive strength, that is 2,8 MPa for FA and 9,9 MPa for POFA. Based on that composition artificial geopolymer aggregates were made and then tested by its specific gravity, gradations andabrations.Keywords: artificial, aggregates, geopolymer, fly ash, palm oil fuel ash

Abstract

The use of Palm Oil Fuel Ash (POFA) as a pozzolanic component in concrete continues in the future due to increase amount of POFA as by-product from industries annually. POFA is used as partial cement replacement in concrete and has significant impact on concrete’s performance. In this research, high volume POFA concrete with POFA replacement of 45%, 55% and 65% by cement mass were studied. POFA was obtained from local quarry in Riau Province. OPC concrete was used as control mix. Some properties namely workability, setting time, compressive strength, shrinkage and porosity were investigated. Results show that workability and compressive strength decreases as the POFA replacement increases in concrete. Porosity, shrinkage and setting time increases with an increase of POFA in concrete. It can be concluded high volume POFA using local material cannot improve the concrete performance significantly. Keywords: compressive strength, performance of concrete, POFA, porosity, pozzolans, shrinkage, setting times, workability
