Abstract

Today, CONCRETE is known as one of the most used building materials in the world. SILICA FUME and its products are now known as one of the best mineral additives in CONCRETE. SILICA FUME is mainly used to improve the properties of hardened CONCRETE so when using SILICA FUME CONCRETE properties after hardening usually more significant. But although various experiments have been conducted on the subject. But this thesis is considering other products of silica impact on the hardened CONCRETE properties have been investigated, including compressive strength, PERMEABILITY and Thawing -freezing of hardened CONCRETE. Three mixing ratio is tested in the laboratory: 1- without additives and 350 kg per cubic meter of cement, 2- with 10% SILICA FUME powder and one percentage lubricant, 3- with 10% of the micro gel. Based on lab work conducted in the research and the gathering of results can be explained by the properties of hardened CONCRETE, the use of powder and gel of SILICA FUME increased compressive strength of 37.5 and 56 percent respectively. Water penetration rate, in the second ratio increase 50 percent and in the third ratio decreased 25 percent, compared to the first ratio. The results indicate the desirability of SILICA FUME gel long-term impact on the quality of hardened CONCRETE including its durability. While the SILICA FUME powder, could adversely affect the PERMEABILITY and Freezing-Thawing of CONCRETE.
