PENGARUH SULFAT TERHADAP KUAT TEKAN BETON DENGAN VARIASI BUBUK KACA SUBSTITUSI SEBAGIAN SEMEN DENGAN w/c 0,60 DAN 0,65
Abstract: Increase of cement
price,causingthe costof concreteproductionmore expensive. To overcome this
problem is to utilize industrial wastes.
The most potential
is waste glass,thatwhen theform
ofvery fine powdershowedpozzolanpropertiesbecause
it containsSiO2. And to improve the durability
ofconcrete, sulfate-resistant concrete studied.Cementin concreteis
replacedbyglasspowderwiththe
proportion of0%, 5%,
10% 15% and20%. Cylindrical specimens
were made with two
different mix designs (w/c
0,6 and 0,65) is
calculated based on ACI method. Specimens soaked in two types of
water, plain water and magnesium sulfate solution for 7, 21, and 28 days. Komala
Sari (2011) examined a concretewithglasspowderas acementreplacementpercentageup
to20% glasspowder, obtained the 5% glass cement replacement concrete achieve
maximum compressive strength. From the research, obtained found
that only the 5% glass
cement replacement concrete
that reached the
design strength. The compressive strength of the 5% glass
cement replacement concrete was the maximum compressive strength. While the
concrete with 15% and 20% glass replacement has a smaller compressive strength
than normal concrete.
