DAMPAK PENGGUNAAN DAN ANALISA PENGARUH STYROFOAM SEBAGAI SUBSTITUSI PASIR DENGAN BAHAN TAMBAH PLASTIMENT-VZ TERHADAP NILAI KUAT TEKAN BETON

Edit
ABSTRACT: As significant there are many major structure is usually at Indonesia, have a lot of done by research to concrete,  and  done  by  admixtures's  increase  to  half  and  half  concrete.  On  this  research  is  made  a  mixed concrete planning styrofoam  without plus material and styrofoam's mixture concrete with added plastiment vz  from  PT.  Sika  Indonesia,  made  using  cement  portland,  base  SK  SNI  0328341993.  There  is  variation  evenmixture styrofoam  to half and half concrete is 0%, 25%, 50% and 75% for type second that concrete, with care condition up to 28 days are soaked. With object tests as cube fairish 15 cm x15 cm x15 cm. Of examination result,  the  greater  substitution  variation  styrofoam    causing  concrete  weight  becomes  lighter  until  variation 75%. Meanwhile for strength to press, the most result optimal is substitution concrete s tyrofoam  with plus material plastiment vz  to K350 25% firmly presses 252,8 Kg / cm². In common substitution concrete styrofoam with plus material for each one concrete quality most turns in at medium strength concrete, and clas's concrete II. (concrete to structural).
