		abstract={Concrete usage in a particular location was also susceptible to Chemical attack and the
environment. This can occur because the most important part of the cement in concrete is a material
that is made up of Chemicals which allow it to react with the Chemical substances in the vicinity.
Attack all compounds, sulfuric acid and this impacted badly on the concrete, the content of sulfate in
the soil, ground water, sea water, industrial waste can result in damage to surrounding structures.
Glass powders are the additives contain substances that can bind to accelerate the reaction
with water and hardening of concrete. In this research will discuss influence the addition of the glass
as a substitute for some sand and fly ash as a substitute for some cement in a concrete with ratio water
cement 0.6 and the percentage of replacement sand by glass powder 0%, 5%, 10% and 15% as well as
a percentage of the replacement of cement by fly ash 0%, 5% and 10% against a strong concrete and
resilience against press sulfate that is printed in the shape of a cylinder with a diameter of 15 cm and a
height o f 30 cm, then soaked with plain water and water containing sulfate, by age 7 the marinade, 21,
and 28 days.
Research, concrete water soaked ordinary and water containing sulphate having strong press
highest on concrete substitutions 5 % powdered glass and 5 % fly ash with nilai 25,97 mpa marinade
regular water and 24,81 mpa marinade water containing sulphate at age 28 days. Effect sulphate
against concrete resulting in a decline strong press concrete, the smallest happens to concrete rate 15
% powder glass and 0 fly ash at age 28 days of -3,92 %. Inconclusive, though increase large
percentage powdered glass in a concrete can be lowered strong press concrete, but influence sulphate
not very significant to a decrease in strong press concrete.}
