Abstract

The use of reactive materials with finer grains, like mikrosilica (silica fume) and superplasticizer enables to produce a more dense concrete with lowwater-cement ratio. Extra dense concrete improves the concrete compressive strength. One way to increase the concrete compressive strength withextra dense concrete manufacture is applying micro-sized particle filler. In addition, aggregate gradation plays an important role in determining thequality of the high performance concrete is grade 80. If the aggregates are finer and their grain are vary, the pore volume of concrete will be less.This is due the tiny grains that fill the pores between the larger grains. Less pore in concrete that leads to form more compact concrete. This studyaims to acces the compressive strength and modulus of elasticity of high performance concrete by varying the size of the aggregates. The study used anexperimental method with a total of 18 samples, there were 3 variations of each sample. Specimens used by cylinder in diameter 7.62 cm and15.24 cm in height. The compressive strength and modulus of elasticity of concrete were tested at the 28 days of concrete age. Compressive strengthof concrete with a larger grain size has a value lower compressive strength than concrete with a small grain size. Concrete made of aggregate size 19mm has the lowest compressive strength recorded 42.66 MPa and its modulus of elasticity was 16366.887 MPa and concrete made of aggregatesize 0.85 mm has the higest compressive strength recorded 84.7 MPa and its modulus of elasticity was 24870.674 MPa. Good aggregategradation will be able to result in maximum density and minimum porosity. This generates higher compressive strength in concrete.

Abstract

The density of concrete is one of aspect which is calculated when planning a building framework because it influencing the weighting calculation. Forthat reason, there are many kinds of research on the lightweight concrete and one of them is making a lightweight concrete using foam technology.Foam lightweight concrete is made by adding foam agent which consist of spectafoam, harder mild, and polymer into a mortar mix. Nowadays, theusing of lightweight concrete still directed only to a non-structural concrete because generally a lightweight concrete has maximum compressivestrength at 15 MPa. The solution to improve this foam lightweight concrete's strength is by adding fiber to the mixing in form of polypropylene Themethod used was experimental observations and theoretical analysis then performed to support the conclusion eventually. The specimen is in form ofcylinder with diameter of 15 cm and height of 30 cm for testing the modulus of elacity, compressive strength, and the split tensile strength. Thisexperiment using CTM (Compression Testing Machine) tool. The result of the research is the increase of the value of foam lightweight concrete'scompressive strength, split tensile strength, and modulus of elasticity on the polypropylene fiber addition rate of 0.75% from the concrete's volumeweight. Fiber additional rate of 0.75% resulting the increase of compressive strength, split tensile strength, and the modulus of elasticityconsecutively 27.93%; 60.38%; and 44.31% compared to the foam lightweight concrete which has no fiber.
