Abstract

Concrete non sand as self is concrete which using its the mixture material harsh aggregate, cemented, water and material added if it is required and eliminates sand in its the mixture. Concrete non sand can be applied at structure, drainage channel underside plate, building is not high rise, and others. But because eliminating sand in its the mixture concrete non sand has many cavities causing can lessen its the compressive strength, to overcome the thing hence applied material to add silica fume in improve, repairing concrete characteristic non sand. This research to know addition influence of silica fume to compressive strength and concrete porosity at the age of 28 days. Examination is done with making specimen 42 composing 7 various that is 0%, 5%, 10%, 15%, 20%, 25%, 30% silica fume from cement weight. Each behavior of consisted of 6 repetition of the size 15×30 cm. Result of research of shows that porosity value increasingly declines along with addition of silica fume while assessing compressive strength to increase with addition of silica fume but addition of optimum fume silica happened at addition of silica fume equal to 7% from cement weight is gotten by porosity equal to 11.5% and concrete compressive strength non sand 245.01 kg/cm2.
