Effects of Mineral Admixtures on Mechanical Properties of Eco-Concrete
摘要
Abstract
Mineral admixtures could be added to replace parts of the cement, many studies on the performance of concrete with mineral admixtures are reported and mineral admixtures has been widely used in the preparation of concrete.Mechanical properties of eco-concrete with mineral admixtures have been studied in this paper.The results show that single add the silica fume or slag has the same effect on the mechanical properties of the ecological concrete.Compared with the blank sample, the mechanical properties of the ecological concrete are significantly increased after the silica fume or slag is added, but has little effect with the increase of the content.With the increase of grade I fly ash, the mechanical properties of eco-concrete are also improved.The influence of the compressive strength on the concrete is the amount of silica fume> slag content> fly ash, and the optimal combination is 6% of silica fume, 30% of slag, 10% of fly ash;The blending of slag powder and fly ash is beneficial to improve the performance of eco-concrete.关键词
