Improving the workability and strength of silica fume concrete by using silane-treated silica fume
Mortar with high workability even without a water-reducing agent and with high tensile and compressive strengths (3.1 and 78 MPa, respectively) was obtained by using as an admixture silica fume that had been surface treated with a silane coupling agent. The treatment enhanced the wettability of silica fume by water, thereby increasing the workability of the mortar mix. It also enhanced the bond...
متن کاملInfluence of Nano-Silica and Silica Fume in the Steel Corrosion Embedded in Concrete
Corrosion of steel is one of the most important potential dangers and threats in concrete structures. Corrosion of steel embedded in reinforced concrete plays a key role in reducing the strength and durability of reinforced concrete. Several studies have proposed that alternative approaches to enhancing the performance of reinforced concrete and its resistance to corrosion. In this study, the r...
متن کاملComparative Study on Effects of Fly Ash, Nano Silica and Silica Fume on Properties of Glass Fiber Reinforced Self Compacting Concrete
Self Compacting concrete (SCC) is a flowing concrete that is able to consolidate under its own weight without any need for vibration. The high fluid nature of SCC makes it suitable for placing it in difficult conditions and in sections with congested reinforcement. Use of SCC overcomes the difficulties pertaining to casting conditions and reduces the man power required. Self compacting concrete...
متن کاملEffects of Silica Fume in Conventional Concrete
The production of tailor made high strength and high performance concrete are made by incorporating silica fume into the normal concrete and it is a routine one in the present days. The mix proportioning is intricate and the design parameters are increased due to the incorporation of silica fume in conventional concrete. The aim of this paper is to look into the different mechanical properties ...
متن کاملAn Experimental Research on Enhancing the Strength and Its Resisting Property of Nano Silica Fly Ash Concrete
This paper deals with the study of Nanotechnology experimentation in Civil Engineering which includes the development, advantages and limitations of Nano concreting technologies. For reducing carbon emission during cement manufacturing fly ash is used as a replacement in ordinary Portland cement which is termed as Portland pozzolana cement(PPC), this inclusion relatively increases the workabili...
