Study on slag powder concrete preparation In Baotou Area

摘要

Using slag powder in concrete, not only can solve the piled slag powder problem in Baotou area, but also can save resources and energy and improve concrete performance, resulting in huge economic benefits. The results showed that slag powder can increase concrete mobility. With slag powder increasing, the C40 and C50 concrete 28d compressive strength increases and then decreases and each age shrinkage values are significantly reduced. When slag powder reach 50% of cement, concrete impermeability and anti-carbonation are excellent and 41.1 yuan are saved every cubic meter concrete which lead to great social and economic benefits.
