Analisis Degradasi Sifat Mekanik Beton yang Ditambah Superplasticizetdan Dibakar Di Atas Suhu 300 Derajat Celcius

Abstract

The aim ofthis research is to observe the transformation ofK225 concrete cube strength
after combusted on temperatures of300, 600 and 900 degree ofCelcius. The test was conducted
on the concrete age of35 days and the mix design was added by superplasticizer to slow down
the concrete formation. The additional superplasticizer will slow down the transformation of
Calciumhydroxide (Ca(OH)) into Calciumoxyde (CaD), so it will lessen the reduction ofconcrete
cube strength due to combustion.
