SKRIPSI TINJAUAN PENGARUH AGREGAT DAUR ULANG BETON TERHADAP KUAT LENTUR
The purpose of this observation is to know the influence of 25% recycle aggregate from concrete fraction aggregate of rough on bending strength of concrete in form of wide log of the size 150 mm, high 150 mm and long 750 mm and also fc-42 MPa. As test object made a same log of the size as much 9 fruit grouped in three group old age the examination. Concrete cylinder used is from the environment of Civil Technique Construction Material Diploma's Laboratory Technique Faculty of Yogyakarta's Gadjah Mada University which later intake sample at random done by inspection of threedbare aggregate as aggregate of concrete mixture.
At this observation, done a bending test on log concrete by enhancing 25% aggregate recycle at harsh aggregate into concrete mixture. Method of concrete scheme weared is "Road Note No.4" method and the test done is bending strenth test pursuant to formula from strength depress and modulus elasticity of concrete at age 3rd, 7th and 28th day later.
From the laboratory test result and calculation of flexibility value and elasticity modulus of pursuant to this methodologies for the concrete recycled aggregate concrete having flexibility value and elasticity modulus obtained at object test the age 28th day is 3,380 MPa and 10441,790 MPa, that can be utilized as material of concrete compiler.
Keyword: flexibility concrete, recycled aggregate, concretelasticity modulus.
