Effect of Limestone Powder on Compressive Strength of Concrete Containing Silica Fume and Optimization of Mix Design Using Response Surface Method
Silica fume has been largely used in concrete in recent decades due to its effect on improvement of strength and durability of concrete. On the other hand, attention has been recently paid to the use of limestone powder as a substitute for part of cement in concrete, basically because of its low price and its positive effect on the durability of concrete. The aim of the current study is the i...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

متن کاملImproving 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 کاملFlexural Fatigue Strength of Steel Fibre Reinforced Concrete Containing Blends of Limestone Powder and Silica Fume
Based upon the statistical distribution of flexural fatigue life data and flexural fatigue strength of the steel fibre reinforced concrete (SFRC) containing blends of limestone powder (LP) and silica fume (SF), the influence of these inserts on the flexural fatigue performance of concretes is probed. Concrete mixes were proportioned to replace 30% cement with these mineral inserts in different ...
