PENGARUH SUBSTITUSI PARSIAL SEMEN DENGAN ABU TERBANG TERHADAP KARAKTERISTIK TEKNIS BETON
Abstract: Partly or totally
substitution of cement with another environmentally products in making concrete
become the alternative. In this research the composition of the fly ash used as
a partial replacement of cement in concrete as much as 40% out of total mass of
cement (High Volume Fly Ash Concrete) and then will be compared with normal
concrete about the technical characteristics of the two types of concrete. The
purpose of this research was to determine the effect of partial replacement of
cement with fly ash in concrete on technical characteristics of concrete which
are specific gravity of concrete, compressive strength of concrete and concrete
abrasion. The results obtained by the technical characteristics of concrete at
the concrete age of 56 days for normal concrete has an average of specific
gravity is 2434.39 kg/m³ with an average of compressive strength is 22.72 MPa
and concrete abrasion percentage is 19.74%, for HVFA concrete has an average of
specific gravity is 2407.22 kg/m³ with an average of compressive strength of
22.51 MPa and concrete abrasion percentage is 20.12%. The result of this
research shows that the effect of the partial replacement of cement with fly
ash in concrete produce the technical characteristics of concrete which are
specific gravity of concrete, compressive strength of concrete and concrete
abrasion are similliar with the technical characteristics of normal concrete.
